I. EXECUTIVE SUMMARY

Calderwood & Harkness LLP ("Calderwood & Harkness" or the "Firm") has been engaged by Optiwave Semiconductor Corp. ("OWS" or the "Petitioner") effective May 20, 2025, to assume management of the company's employment-based immigration program, including all pending visa petitions and related matters previously handled by Whitfield & Parekh LLP ("Whitfield & Parekh" or "Prior Counsel"), whose engagement with OWS concluded on April 30, 2025. The transition of counsel was driven by firm capacity constraints at Whitfield & Parekh and the broader consolidation of outside legal services across the portfolio companies of Crestline Ventures Fund IV, LP, OWS's majority shareholder.

This memorandum addresses the most time-sensitive of the matters currently in transition: a pending Request for Evidence ("RFE") issued by U.S. Citizenship and Immigration Services ("USCIS") in connection with the H-1B extension petition filed on behalf of Takeshi Nakamura ("Nakamura" or the "Beneficiary"), a Signal Integrity Engineer employed at OWS's San Jose headquarters. The underlying extension petition, Form I-129 with H-1B classification supplement, was filed on March 15, 2025 by Kavita Parekh of Whitfield & Parekh LLP. USCIS subsequently issued an RFE challenging whether the Signal Integrity Engineer position qualifies as a "specialty occupation" within the meaning of section 214(i)(1) of the Immigration and Nationality Act ("INA") and 8 C.F.R. § 214.2(h)(4)(ii).

The RFE focuses on the position's classification under Standard Occupational Classification ("SOC") Code 17-2072 (Electronics Engineers, Except Computer). Specifically, USCIS has questioned whether the position requires a minimum of a bachelor's degree or higher in a specific specialty directly related to the position as a normal minimum requirement for entry, whether such a degree requirement is common across the industry for parallel positions, and whether the duties are sufficiently specialized to require the theoretical and practical application of a body of highly specialized knowledge. These inquiries are consistent with the types of scrutiny that USCIS has applied to engineering positions with increasing frequency since the issuance of revised adjudication guidance beginning in 2017.

From a timing perspective, Nakamura's I-94 Arrival/Departure Record expired on May 31, 2025. However, because the extension petition was timely filed on March 15, 2025 — more than two months prior to the I-94 expiration — Nakamura is authorized to continue employment with OWS in the same position and under the same terms for up to 240 days beyond the I-94 expiration date, pursuant to 8 C.F.R. § 214.2(h)(2)(i)(H). This means Nakamura's employment authorization under the 240-day rule extends through approximately January 25, 2026, provided the extension petition remains pending and is not denied during that period.

Urgency: The exact date of the RFE issuance and the corresponding response deadline have not yet been confirmed by Calderwood & Harkness, as the complete case file is still in transit from Whitfield & Parekh. The target completion date for the file transfer is June 15, 2025. Standard RFE response windows are either 60 or 87 calendar days from the date of issuance. The precise deadline is critical, and confirming it is the Firm's most immediate priority. Failure to respond within the prescribed period would result in adjudication of the petition based on the existing record, which, given the specialty occupation challenge, would likely result in denial.

The recommended response strategy is organized around four pillars:

(1) Regulatory analysis of the specialty occupation criteria and position-specific argumentation demonstrating that the Signal Integrity Engineer position satisfies each of the four alternative regulatory criteria set forth in 8 C.F.R. § 214.2(h)(4)(ii);

(2) Industry expert declarations from semiconductor and photonics professionals — including academic experts and senior practitioners — attesting to the universal degree requirement for signal integrity engineering positions in the semiconductor industry;

(3) Analysis of the Department of Labor ("DOL") Occupational Outlook Handbook ("OOH") and the O*NET OnLine database for SOC 17-2072, confirming the bachelor's degree requirement for the occupation; and

(4) Comparable position data from peer semiconductor employers, including a compilation of current and recent job postings and an analysis of OWS's own internal hiring history, demonstrating the industry-wide and employer-specific consistency of the degree requirement.

Additionally, Nakamura has a pending EB-1B outstanding researcher petition with a priority date of September 10, 2022. While the H-1B specialty occupation analysis is position-focused rather than beneficiary-focused, Nakamura's extraordinary qualifications — which formed the basis of the EB-1B filing — underscore the highly specialized nature of the work he performs at OWS and the level of expertise that OWS requires for this position. This fact can and should be leveraged in the RFE response.

Calderwood & Harkness believes that a comprehensive, evidence-rich response addressing each of USCIS's specific concerns should result in approval of the extension petition. The balance of this memorandum sets forth the factual background, legal framework, detailed response strategy, recommended evidentiary package, risk assessment, action items, timeline, and budget estimate for the RFE response.

II. BACKGROUND

A. Beneficiary Profile — Takeshi Nakamura

Takeshi Nakamura is a Japanese national currently employed by OWS as a Signal Integrity Engineer at the company's headquarters in San Jose, California. The following summarizes the key facts and immigration history relevant to the pending RFE:

Nakamura's educational credentials and publication record are central to the EB-1B outstanding researcher petition and will be confirmed upon receipt of the complete file from Whitfield & Parekh. Based on the information available to Calderwood & Harkness from OWS's internal records and preliminary discussions with Rajesh Anand, Nakamura holds at minimum a bachelor's degree in electrical engineering or a closely related discipline and has published extensively in peer-reviewed journals in the signal integrity and photonics fields. His EB-1B filing indicates recognition as an outstanding researcher with international standing in his area of expertise. These credentials substantially exceed the minimum requirements for the Signal Integrity Engineer position and serve as additional evidence that the position demands a high level of specialized knowledge.

Nakamura has been employed by OWS since June 1, 2022, when his current H-1B validity period commenced. Prior to his employment with OWS, it is understood that Nakamura held H-1B status with a prior employer, although the details of his earlier immigration history will be confirmed from the transferred file. His continuous maintenance of H-1B status and timely filing of the extension petition are essential predicates for the 240-day employment authorization rule that currently governs his work authorization.

B. Petitioner Profile — Optiwave Semiconductor Corp.

Optiwave Semiconductor Corp. is a Delaware corporation qualified to do business in California, Texas, and Oregon. OWS was founded on March 14, 2017 and is headquartered at 4820 Veltrano Parkway, Suite 300, San Jose, California 95134. The company's Federal Employer Identification Number ("FEIN") is 82-4931076, and it operates under NAICS Code 334413 (Semiconductor and Related Device Manufacturing).

OWS specializes in the design and fabrication of photonic integrated circuits ("PICs") for data center interconnect applications. The company develops advanced silicon photonic and indium phosphide-based transceivers and related optical components that enable high-speed data transmission within and between cloud computing data centers. OWS's products operate at the frontier of optical communications technology, requiring its engineering workforce to possess deep expertise in semiconductor physics, electromagnetic theory, photonics, analog and mixed-signal circuit design, and related disciplines.

As of the date of this memorandum, OWS employs approximately 340 individuals across three offices and a remote workforce:

• San Jose, California (headquarters): approximately 210 employees

• Austin, Texas: approximately 65 employees

• Portland, Oregon: approximately 40 employees

• Remote personnel: approximately 25 employees

The company reported annual revenue of $187.4 million for fiscal year 2024, as reflected in its audited financial statements prepared by Pendleton Accounting Group LLP. OWS's majority shareholder is Crestline Ventures Fund IV, LP, which acquired a 62.4% equity stake in the company on September 15, 2022. The Crestline transaction brought OWS into a portfolio of growth-stage semiconductor and advanced technology companies, and it was Crestline's portfolio-wide consolidation of outside counsel that ultimately precipitated the transition from Whitfield & Parekh to Calderwood & Harkness.

OWS is enrolled in the E-Verify program (Company ID: 1487623) and is classified as an H-1B non-dependent employer. The company currently sponsors 14 H-1B workers out of its total workforce of approximately 340, representing 4.12% of its employee base. This figure is well below the 15% threshold that would trigger H-1B dependency requirements under INA § 212(n)(3) and the associated attestation obligations. OWS's non-dependent status simplifies certain aspects of the H-1B petition process and reduces the applicable compliance burdens.

The hiring manager and technical attestor for the Nakamura petition is Dr. Yun-Sheng Chen, Vice President of Engineering at OWS. Dr. Chen oversees the company's signal integrity, analog IC design, and photonics engineering teams, and he is directly responsible for defining the educational and technical qualifications required for engineering positions within his division. Dr. Chen's support letter will be a cornerstone of the RFE response, and his participation in identifying potential expert declarants will be essential.

Additional OWS personnel who will be involved in the RFE response effort include:

• Patricia Langford, General Counsel, who serves as the primary legal contact for the OWS engagement and who has authority to approve external legal expenditures and strategic decisions related to the company's immigration program.

• Rajesh Anand, Immigration Program Manager, who manages day-to-day immigration matters, coordinates with outside counsel, and interfaces with OWS's human resources department on immigration-related employment documentation.

• Samantha Kowalski, Director of Human Resources, who maintains employee records, including educational credentials and hiring data, and who will be responsible for providing the internal hiring history data needed for the RFE response.

C. Prior Counsel Transition

Whitfield & Parekh LLP, under the direction of Kavita Parekh, Partner, served as OWS's primary immigration counsel from June 1, 2019 through April 30, 2025. During this six-year engagement, Whitfield & Parekh handled OWS's full range of employment-based immigration matters, including H-1B petitions, PERM labor certifications, I-140 immigrant petitions, and related filings.

The transition from Whitfield & Parekh to Calderwood & Harkness was prompted by two concurrent factors. First, Whitfield & Parekh experienced significant capacity constraints beginning in late 2024, which resulted in delays in filing timelines and limited availability of senior attorneys for strategic consultations. Second, Crestline Ventures Fund IV, LP — OWS's majority shareholder — initiated a portfolio-wide consolidation of outside legal services in the first quarter of 2025, directing its portfolio companies to engage a smaller number of pre-approved law firms for specialized legal work, including immigration. Calderwood & Harkness was selected as one of three approved immigration counsel for Crestline portfolio companies, and OWS's engagement with the Firm commenced on May 20, 2025.

A formal file transfer request was submitted to Whitfield & Parekh on May 22, 2025. The target completion date for the transfer is June 15, 2025. The Nakamura RFE file is among three pending RFE matters being transferred to Calderwood & Harkness. The two other pending RFEs involve separate OWS employees and different adjudicatory issues, and they will be addressed in separate memoranda following file receipt and review.

It is imperative that Calderwood & Harkness obtain the exact RFE issuance date and response deadline for the Nakamura matter immediately upon receipt of the file — or, if possible, in advance of the full file transfer. Megan Chu and Tanya Benavides have been directed to contact Whitfield & Parekh to request, at minimum, a copy of the RFE notice itself, even before the remainder of the file is transferred, so that the response deadline can be confirmed and the response timeline can be finalized. Rajesh Anand has been separately asked to check whether OWS received a copy of the RFE notice directly from USCIS or from Whitfield & Parekh.

The original petition and all supporting materials filed by Whitfield & Parekh are under review and will be thoroughly analyzed by Calderwood & Harkness upon receipt. Where deficiencies in the original filing may have contributed to the issuance of the RFE, Calderwood & Harkness will supplement the record with additional evidence and argumentation. It is not unusual for an RFE to be issued where the initial filing, while competent, did not include sufficient granular evidence of the degree requirement's universality in the industry or detailed duty-to-coursework mapping — both of which will be central to our response strategy.

D. The RFE — Nature of the Challenge

USCIS issued a Request for Evidence challenging the specialty occupation classification of the Signal Integrity Engineer position at OWS. While the precise text of the RFE has not yet been reviewed by Calderwood & Harkness (pending file transfer), the nature of the challenge has been communicated by Rajesh Anand based on his discussions with Whitfield & Parekh and his review of a summary provided by Kavita Parekh prior to the engagement's conclusion. Based on this information and our extensive experience with specialty occupation RFEs in the engineering context, we anticipate that the RFE raises the following specific concerns:

(1) Whether the Signal Integrity Engineer position requires a minimum of a bachelor's degree or higher in a specific specialty directly related to the position as a normal minimum requirement for entry into the occupation;

(2) Whether the degree requirement is common across the industry for parallel positions among similar organizations, or, alternatively, whether the position is so complex or unique that it can be performed only by an individual with a degree;

(3) Whether the job duties described in the petition are sufficiently specialized to require the theoretical and practical application of a body of highly specialized knowledge; and

(4) Whether OWS can establish that it normally requires a bachelor's degree or its equivalent in a specific specialty for the Signal Integrity Engineer position.

These four areas of inquiry map directly to the four alternative regulatory criteria for specialty occupation classification under 8 C.F.R. § 214.2(h)(4)(ii), and the RFE response must systematically address each one. This type of RFE is consistent with the heightened scrutiny that USCIS has applied to engineering positions since the issuance of revised policy guidance in 2017 and in light of the adjudicatory framework established in Matter of Simeio Solutions, LLC, 26 I&N Dec. 542 (AAO 2015), which, while primarily addressing Labor Condition Application ("LCA") amendments for worksite changes, reflects USCIS's broader emphasis on strict compliance with the conditions of H-1B employment.

It is worth noting that specialty occupation RFEs for electronics engineering positions classified under SOC 17-2072 are less common than those issued for computer-related occupations (SOC 15-series codes), precisely because the DOL's own Occupational Outlook Handbook unambiguously states that a bachelor's degree in electrical engineering or a related engineering discipline is required for entry into the occupation. This fact provides a strong foundation for the RFE response, and the issuance of the RFE may reflect deficiencies in the evidentiary support provided with the original petition rather than any genuine ambiguity about the occupation's specialty nature.

III. LEGAL FRAMEWORK — SPECIALTY OCCUPATION CLASSIFICATION

A. Statutory Standard — INA § 214(i)(1)

Section 214(i)(1) of the Immigration and Nationality Act defines a "specialty occupation" as an occupation that requires:

(A) theoretical and practical application of a body of highly specialized knowledge, and

(B) attainment of a bachelor's or higher degree in the specific specialty (or its equivalent) as a minimum for entry into the occupation in the United States.

This statutory definition establishes a two-part test. First, the position must involve the theoretical and practical application of a body of "highly specialized knowledge" — that is, the work cannot consist merely of routine tasks or the mechanical application of established procedures, but must demand the application of specialized theoretical principles and advanced practical expertise. Second, the position must require, as a minimum for entry, the attainment of a bachelor's degree or higher in a "specific specialty" directly related to the position. The specificity requirement is critical: a general bachelor's degree in any field does not satisfy the statute. Rather, the degree must be in a specific academic discipline — such as electrical engineering, electronics engineering, or physics — that is directly related to the duties of the position.

For the Signal Integrity Engineer position at OWS, both prongs of this statutory test are readily satisfied. The position involves the application of advanced principles of electromagnetic theory, semiconductor physics, transmission line theory, and signal processing — all of which constitute a body of highly specialized knowledge that is the subject of specific academic programs in electrical and electronics engineering. Moreover, as demonstrated by the DOL's Occupational Outlook Handbook and the consistent hiring practices of OWS and its industry peers, a bachelor's degree in electrical engineering, electronics engineering, physics, or a closely related discipline is the universally recognized minimum qualification for entry into signal integrity engineering positions.

B. Regulatory Criteria — 8 C.F.R. § 214.2(h)(4)(ii)

The implementing regulations at 8 C.F.R. § 214.2(h)(4)(ii) provide that a petitioner may establish specialty occupation status by demonstrating that the position meets at least one of four alternative criteria. While a petitioner need only satisfy one criterion for approval, a robust RFE response should address all four to maximize the probability of approval. The four criteria are as follows:

Criterion 1: A baccalaureate or higher degree or its equivalent is normally the minimum requirement for entry into the particular position.

This criterion focuses on the occupation as a whole. The petitioner must demonstrate that the normal minimum educational requirement for the position — not merely the employer's preferred or ideal qualification, but the standard minimum requirement recognized across the field — is a bachelor's degree or higher in a specific specialty. The word "normally" has been the subject of extensive litigation and adjudicatory guidance. USCIS Policy Memorandum PM-602-0142.1 (discussed below) clarified that "normally" does not require that a degree is always required, but rather that it is the typical or standard minimum requirement for entry. This criterion is most effectively addressed through reference to the DOL Occupational Outlook Handbook, O*NET data, and industry-wide hiring practices.

Criterion 2: The degree requirement is common to the industry in parallel positions among similar organizations, or, in the alternative, the particular position is so complex or unique that it can be performed only by an individual with a degree.

This criterion contains two alternative sub-tests. Under the first sub-test, the petitioner must show that the degree requirement is common across the industry for parallel positions at similar organizations — a showing that is effectively made through a compilation of comparable job postings from peer employers. Under the second sub-test, the petitioner may alternatively show that the position itself is so complex or unique that only a degreed individual could perform the duties. For a signal integrity engineering position in the semiconductor industry, both sub-tests are satisfied, but the first sub-test is more straightforward to document.

Criterion 3: The employer normally requires a degree or its equivalent for the position.

This criterion is employer-specific rather than industry-wide. The petitioner must demonstrate its own established practice of requiring a bachelor's degree in a specific specialty for the position in question. This showing is made through the employer's internal hiring records, human resources policies, and attestations from management personnel. If OWS has consistently required a bachelor's degree in electrical engineering, electronics engineering, or physics for all signal integrity engineering hires, this criterion is directly satisfied.

Criterion 4: The nature of the specific duties is so specialized and complex that knowledge required to perform them is usually associated with the attainment of a baccalaureate or higher degree.

This criterion focuses on the duties themselves rather than the occupation in the abstract or the employer's historical practices. The petitioner must demonstrate that the specific duties assigned to the beneficiary are sufficiently specialized and complex that the knowledge necessary to perform them is typically acquired through a bachelor's or higher degree program in a specific discipline. This criterion requires a granular analysis of job duties and a mapping of those duties to the curriculum of relevant degree programs.

Our response strategy addresses all four criteria, with the strongest emphasis on Criteria 1, 2, and 4, as these are the criteria most likely to be questioned by the adjudicating officer and the criteria for which the available evidence is most robust.

C. Relevant Precedent and Guidance

Several key sources of administrative precedent and policy guidance inform the RFE response strategy:

Matter of Simeio Solutions, LLC, 26 I&N Dec. 542 (AAO 2015). Although this precedent decision primarily addresses the requirement for an amended LCA when there is a material change in the terms and conditions of H-1B employment — particularly changes in worksite — it has broader implications for H-1B adjudication. Simeio Solutions reflects USCIS's heightened emphasis on ensuring that the terms of H-1B employment are precisely documented and consistently maintained. In the context of the Nakamura RFE response, Simeio Solutions underscores the importance of demonstrating that the current LCA on file is fully compliant and that the position as described is consistent with the certified LCA terms, including the SOC classification, prevailing wage level, and worksite location.

USCIS Policy Memorandum PM-602-0142.1 (Rescission of Prior Restrictive Guidance). This policy memorandum, issued in 2020, rescinded earlier memoranda that had imposed restrictive interpretive standards on specialty occupation adjudications. The rescinded guidance had been criticized by immigration practitioners, industry groups, and federal courts for, among other things, requiring petitioners to demonstrate that a degree is always required for the occupation — a standard that exceeded the regulatory text of "normally." PM-602-0142.1 restored the pre-2017 adjudicatory framework and confirmed that the "normally" standard under Criterion 1 does not demand absolute universality of the degree requirement; rather, it requires that a bachelor's degree in a specific specialty is the standard or typical minimum requirement for entry into the occupation. This rescission is directly supportive of the Nakamura RFE response, particularly given that the OOH for SOC 17-2072 expressly states a degree requirement.

Administrative Appeals Office Decisions — Engineering Positions. The AAO has sustained numerous appeals and affirmed specialty occupation classification for engineering positions in the semiconductor, electronics, and related industries. While AAO non-precedent decisions are not binding, they reflect the agency's consistent recognition that electrical and electronics engineering positions — particularly those involving advanced signal integrity, electromagnetic simulation, and semiconductor device design — inherently require a bachelor's degree in a specific engineering discipline. We will identify and cite relevant AAO decisions in the cover letter accompanying the RFE response.

Federal Court Decisions. Federal district courts have repeatedly reinforced the principle that USCIS must give appropriate deference to the employer's reasonable business judgment regarding degree requirements where that judgment is supported by evidence. Courts have vacated USCIS denials of H-1B petitions where the agency substituted its own assessment of position requirements for the employer's documented, evidence-backed determination. These decisions are particularly relevant where, as here, the employer (OWS) has a consistent track record of requiring a specific degree for the position, the DOL's own publications confirm the degree requirement, and the position involves highly specialized technical duties that manifestly require degree-level training.

IV. RESPONSE STRATEGY — FOUR PILLARS

The RFE response will be organized around four complementary evidentiary pillars, each designed to address one or more of the four regulatory criteria and to respond to the specific concerns raised in the RFE. Together, these pillars will present a comprehensive, multi-layered case for specialty occupation classification that addresses the issue from regulatory, academic, industry, and employer-specific perspectives.

A. Pillar 1: Regulatory Analysis and Position-Specific Argumentation

The first pillar focuses on the legal and factual analysis of the Signal Integrity Engineer position itself, demonstrating through detailed examination of the job duties, the minimum degree requirement, and the nexus between the two that the position satisfies the statutory and regulatory definition of a specialty occupation.

1. Detailed Job Duties Analysis

The Signal Integrity Engineer position at OWS is a highly specialized technical role situated within the company's photonic integrated circuit ("PIC") engineering division. Nakamura's duties encompass the full lifecycle of signal integrity engineering for advanced optical transceiver platforms, from initial design and simulation through characterization and validation. The principal duties of the position include the following:

• Analysis of high-speed signal propagation in photonic integrated circuits. Nakamura is responsible for analyzing the behavior of electrical and optical signals as they propagate through PIC structures, including modeling signal attenuation, dispersion, and reflection at material interfaces and interconnect junctions. This work requires the application of Maxwell's equations and electromagnetic wave theory to complex, multi-layered semiconductor structures operating at data rates of 100 Gbps and above.

• Electromagnetic simulation and modeling of interconnect structures. Nakamura uses commercial electromagnetic simulation tools — including Crowne Albany Data Systems, Tarrant Services Inc., and Beaumont Systems — to model the electromagnetic behavior of chip-to-package and package-to-board interconnect structures. This simulation work requires a deep understanding of computational electromagnetics, finite element analysis, and the physical properties of semiconductor materials, dielectrics, and metallization layers.

• Design of signal conditioning circuits for data center optical transceivers. Nakamura participates in the design of equalization, pre-emphasis, and de-emphasis circuits that optimize signal quality for data center interconnect applications. This work requires knowledge of high-frequency analog circuit design, linear systems theory, and digital signal processing techniques applied to serial data communication channels.

• Characterization of crosstalk, jitter, and insertion loss in PIC platforms. Nakamura conducts laboratory measurements and data analysis to characterize key signal integrity metrics, including far-end and near-end crosstalk, deterministic and random jitter components, and frequency-dependent insertion loss across the operating bandwidth of OWS's transceiver products. This work requires proficiency in vector network analyzer measurements, time-domain reflectometry, eye diagram analysis, and S-parameter extraction and interpretation.

• Collaboration with analog IC design and packaging engineering teams. Nakamura works closely with OWS's analog integrated circuit designers and packaging engineers to ensure that signal integrity requirements are met throughout the design process, from initial circuit specification through final package design and board-level integration. This collaboration requires the ability to translate signal integrity analysis results into actionable design constraints and to evaluate design trade-offs across multiple engineering disciplines.

A detailed percentage breakdown of Nakamura's time allocation across these and related duties will be prepared as an exhibit to the RFE response (Exhibit B), following the standard format for duty description exhibits used in H-1B specialty occupation filings. The percentage breakdown will be reviewed and attested to by Dr. Yun-Sheng Chen, VP of Engineering, who has direct supervisory responsibility for Nakamura's work.

The critical point to be emphasized in the RFE response is that each of these duties requires the application of advanced theoretical knowledge drawn from specific academic disciplines — electromagnetic theory, semiconductor physics, analog circuit design, and digital signal processing — that are taught at the bachelor's and graduate levels in accredited programs in electrical engineering, electronics engineering, and physics. These are not duties that can be performed by individuals with general education or through on-the-job training alone. The theoretical foundations are prerequisites, not supplements, to the practical skills applied in the role.

2. Minimum Degree Requirement Attestation

OWS requires a minimum of a Bachelor of Science degree in Electrical Engineering, Electronics Engineering, Physics, or a closely related field for the Signal Integrity Engineer position. This requirement is not merely a preference or aspiration; it is an absolute minimum qualification that OWS has consistently applied in its hiring for this position and for all comparable engineering positions within its photonics and signal integrity engineering teams.

The RFE response will include a detailed support letter from Dr. Yun-Sheng Chen, Vice President of Engineering, on OWS letterhead (Exhibit A). Dr. Chen's letter will attest to the following:

• OWS has established, and consistently enforces, a minimum educational requirement of a B.S. degree in Electrical Engineering, Electronics Engineering, Physics, or a closely related field for all Signal Integrity Engineer positions;

• This degree requirement reflects OWS's assessment that the duties of the Signal Integrity Engineer position cannot be competently performed without the foundational theoretical knowledge acquired through a structured degree program in the specified disciplines;

• OWS has never hired a Signal Integrity Engineer — or, to the extent applicable, any engineer in a comparable role within the signal integrity or photonics engineering teams — without at minimum a bachelor's degree in one of the specified disciplines;

• The degree requirement is consistent with the requirements applied by OWS's competitors and peers in the semiconductor and photonics industries; and

• Nakamura himself meets and substantially exceeds the minimum degree requirement, as evidenced by his academic credentials and his recognition as an outstanding researcher in the field (as reflected in his pending EB-1B petition).

Dr. Chen's letter will be drafted by Calderwood & Harkness (Derek Okonkwo, working associate) in close consultation with Dr. Chen and Rajesh Anand, to ensure technical accuracy and consistency with all other documentation in the record. The letter will be provided to Dr. Chen for review, revision as necessary, and execution on OWS letterhead.

3. Nexus Between Degree and Duties

A central component of the Pillar 1 analysis is a detailed mapping of specific job duties to specific university coursework, demonstrating that the knowledge required to perform the Signal Integrity Engineer duties is acquired through the structured curriculum of a bachelor's degree program in the relevant engineering or physical science disciplines. This duty-to-coursework mapping serves to rebut any argument that the position's knowledge requirements could be met through general education, unrelated degree programs, or informal on-the-job training.

The mapping will correlate each principal duty with specific courses that are standard components of accredited B.S. programs in Electrical Engineering, including but not limited to:

This table will be expanded and refined in the RFE response cover letter and in the supporting exhibits. Copies of relevant course syllabi from accredited B.S. programs in Electrical Engineering will be submitted as Exhibit L to further substantiate the nexus between the degree requirement and the position duties.

The argumentation will emphasize that the knowledge required for the Signal Integrity Engineer position is not merely "useful" or "helpful" but is essential — and that this essential knowledge is acquired through the specific, multi-year curriculum of a bachelor's degree program in the relevant engineering disciplines. An individual without this educational foundation would lack the theoretical framework necessary to perform even the most basic duties of the position, such as interpreting S-parameter data, setting up electromagnetic simulations, or designing equalization circuits for high-speed serial links.

B. Pillar 2: Industry Expert Declarations

The second pillar involves the procurement and submission of expert declarations from qualified individuals in the semiconductor and signal integrity engineering fields. Expert declarations serve as independent, third-party validation that the degree requirement is inherent to the occupation and is not merely an idiosyncratic preference of the petitioning employer.

1. Identification of Expert Declarants

Calderwood & Harkness recommends obtaining two to three expert declarations from individuals representing a cross-section of the signal integrity and semiconductor engineering community. The ideal declarant panel would include:

(a) Academic expert(s) in electrical engineering / signal integrity. Professors at research universities with established semiconductor engineering programs are particularly well-positioned to attest to the educational requirements of signal integrity engineering positions. Such declarants can speak authoritatively to the curriculum content of B.S. programs in electrical engineering, the theoretical knowledge that students acquire through these programs, and the direct applicability of that knowledge to signal integrity work in the semiconductor industry. Potential institutions include Stanford University, UC Berkeley, Georgia Institute of Technology, Purdue University, and the University of Michigan — all of which have leading programs in semiconductor device physics, electromagnetic theory, and signal integrity.

(b) Senior industry practitioners at peer semiconductor companies. Declarations from senior engineers or engineering managers at companies comparable to OWS — including other photonics, semiconductor, and data center interconnect firms — would demonstrate that the degree requirement is common across the industry for parallel positions. These declarants can attest from their own hiring experience and professional knowledge that signal integrity engineering positions in the semiconductor industry universally require a B.S. degree in electrical engineering, electronics engineering, or physics. Names of potential declarants will be identified with the assistance of Dr. Yun-Sheng Chen, who maintains professional relationships with counterparts at peer companies through industry conferences, IEEE activities, and professional networks.

(c) Professional association representatives. A declaration from a representative of a relevant professional organization — such as the Institute of Electrical and Electronics Engineers ("IEEE"), the Signal Integrity Society, the Optical Society of America, or the Semiconductor Industry Association — would provide additional institutional validation of the degree requirement. Alternatively, a third industry expert or academic declarant may be substituted if a professional association declaration proves difficult to obtain within the available timeframe.

2. Content of Expert Declarations

Each expert declaration will be drafted by Calderwood & Harkness (Megan Chu, associate) and will be submitted to the declarant for review, revision, and execution under penalty of perjury. The declarations will be tailored to each declarant's specific expertise and professional background, but all declarations should attest to the following core points:

(a) Signal Integrity Engineer positions in the semiconductor industry universally require, as a minimum educational qualification, a Bachelor of Science degree in Electrical Engineering, Electronics Engineering, or Physics (or a closely related discipline such as Applied Physics or Computer Engineering with an emphasis in electromagnetics);

(b) The work performed by a Signal Integrity Engineer — including electromagnetic simulation, high-speed signal analysis, crosstalk and jitter characterization, and signal conditioning circuit design — cannot be competently performed by individuals who do not possess such a degree;

(c) The specific duties described in the OWS Signal Integrity Engineer position are consistent with the duties performed by degree-holding signal integrity engineers throughout the semiconductor and photonics industries;

(d) The position involves the theoretical and practical application of a highly specialized body of knowledge, including electromagnetic theory, transmission line theory, semiconductor device physics, and high-frequency circuit design; and

(e) The educational qualifications required for the position are acquired through the structured curriculum of an accredited bachelor's degree program in the relevant disciplines and cannot be acquired through general education, unrelated degree programs, or on-the-job training alone.

In addition to these core attestations, each declaration should reference specific technical competencies that are hallmarks of the signal integrity engineering profession and that require degree-level training:

• S-parameter analysis and extraction

• Eye diagram interpretation and compliance testing

• Channel modeling and simulation using industry-standard tools (Crowne Albany Data Systems, Tarrant Services Inc., Beaumont Systems, Marlowe Services Inc.)

• Electromagnetic interference ("EMI") and electromagnetic compatibility ("EMC") mitigation

• Time-domain reflectometry ("TDR") measurements

• Power integrity analysis and simultaneous switching noise ("SSN") evaluation

• Impedance matching and controlled impedance design for multi-gigabit serial links

The inclusion of these specific technical competencies serves to demonstrate the depth and specificity of the knowledge required for the position, reinforcing the argument that a general bachelor's degree — or a degree in an unrelated field — would be wholly insufficient to prepare an individual for signal integrity work.

3. Timeline for Securing Declarations

Securing expert declarations is typically the most time-intensive element of an RFE response, as it requires identifying willing declarants, coordinating with their schedules, drafting declarations tailored to their expertise, and allowing sufficient time for review and execution. The following timeline is recommended:

• Identification and outreach: Potential declarants should be identified and approached within five (5) business days of the completion of the file transfer from Whitfield & Parekh. Dr. Lena Marchetti will take the lead on academic expert outreach, leveraging her professional network in the engineering education community. Dr. Yun-Sheng Chen will be asked to identify appropriate industry contacts for practitioner declarations.

• Drafting: Allow ten (10) to fifteen (15) business days for declaration drafting, review by the declarant, revisions, and final execution. Megan Chu will be responsible for preparing initial drafts of all declarations.

• Coordination: Dr. Yun-Sheng Chen and Rajesh Anand will facilitate introductions between Calderwood & Harkness and potential industry declarants. All communications with declarants will be managed by Calderwood & Harkness to ensure consistency and quality of the declarations.

Given the importance of the declarations to the overall RFE response and the lead time required, the declarant identification and outreach process should commence as soon as practicable, even before the complete file transfer is finalized, if the RFE response deadline permits.

C. Pillar 3: DOL Occupational Outlook Handbook and O*NET Analysis

The third pillar relies on the U.S. Department of Labor's own publications — the Occupational Outlook Handbook and the O*NET OnLine database — to establish that the Signal Integrity Engineer position, classified under SOC Code 17-2072 (Electronics Engineers, Except Computer), is recognized by the federal government as requiring a bachelor's degree in a specific engineering discipline.

1. OOH Entry for Electronics Engineers, Except Computer (SOC 17-2072)

The DOL Occupational Outlook Handbook is the primary reference source used by USCIS adjudicators in evaluating specialty occupation claims, and it is often the single most persuasive piece of evidence in an RFE response. The OOH entry for Electronics Engineers, Except Computer expressly states that electronics engineers "need a bachelor's degree in electrical engineering, electronics engineering, or a related engineering field." This language is direct and unambiguous: the OOH identifies a bachelor's degree in a specific engineering discipline as the standard educational requirement for entry into the occupation.

The RFE response will present relevant excerpts from the OOH entry for SOC 17-2072, including:

• Education requirements section: The OOH's statement that a bachelor's degree in electrical engineering, electronics engineering, or a related engineering field is required for entry-level positions. This directly supports Criterion 1 of the regulatory test, which asks whether a baccalaureate degree is "normally the minimum requirement for entry into the particular position."

• Job duties description: The OOH describes the work of electronics engineers as involving the design, development, and testing of electronic components and systems, including communications systems, sensors, and electronic circuits. The description maps directly to Nakamura's signal integrity duties at OWS, which center on the design, simulation, and characterization of electronic and photonic components for data center communication systems.

• Work environment section: The OOH describes the work environments typical for electronics engineers, including laboratories, offices, and manufacturing facilities — all consistent with Nakamura's work environment at OWS.

The RFE response will emphasize that USCIS's own adjudication guidance identifies the OOH as a relevant source for determining whether an occupation normally requires a bachelor's degree in a specific specialty. Where the OOH expressly states a degree requirement, as it does for SOC 17-2072, USCIS should give that determination substantial weight in its adjudication.

2. O*NET Profile for SOC 17-2072

The ONET OnLine database, also maintained by the DOL, provides detailed occupational information that supplements the OOH. The ONET profile for SOC 17-2072 will be used to reinforce the OOH's degree requirement and to provide additional granular data on the knowledge, skills, and abilities required for the occupation.

Key O*NET data points to be cited in the RFE response include:

• Job Zone classification: SOC 17-2072 is classified as Job Zone 4 ("Considerable Preparation Needed") or Job Zone 5 ("Extensive Preparation Needed"), depending on the specific edition and subcategory. Both classifications indicate that the occupation requires significant formal educational preparation, typically including a bachelor's degree or higher.

• Specific Vocational Preparation ("SVP") range: The SVP range for the occupation indicates the amount of time required to learn the techniques, acquire the information, and develop the facility needed for average performance. For electronics engineers, the SVP range is consistent with the attainment of a bachelor's degree.

• Knowledge, skills, and abilities ("KSA") profile: The O*NET KSA profile for SOC 17-2072 identifies critical knowledge domains (e.g., engineering and technology, physics, mathematics, computers and electronics, design), essential skills (e.g., complex problem solving, critical thinking, systems analysis, programming), and required abilities (e.g., deductive reasoning, mathematical reasoning, information ordering). The RFE response will cross-reference this KSA profile with the specific duties and qualifications of the Signal Integrity Engineer position at OWS to demonstrate alignment.

• Education data: O*NET collects and reports data on the educational attainment of workers in each occupation. For SOC 17-2072, the data consistently shows that an overwhelming percentage of workers hold a bachelor's degree or higher — typically exceeding 85-90%. This empirical data further supports the conclusion that a bachelor's degree is the normal minimum requirement for entry into the occupation.

3. Bureau of Labor Statistics Wage Data

The Bureau of Labor Statistics ("BLS") prevailing wage data for SOC 17-2072 in the relevant Metropolitan Statistical Area provides additional context for the specialty occupation analysis. While wage data is not, by itself, dispositive of specialty occupation status, it provides corroborating evidence of the position's level of specialization and the qualifications required.

For the San Jose-Sunnyvale-Santa Clara, CA MSA, the prevailing wage levels for SOC 17-2072 (Electronics Engineers, Except Computer) are approximately:

• Level I (entry-level): approximately $120,806/year

• Level II: approximately $139,318/year

• Level III: approximately $157,830/year

• Level IV (fully competent): approximately $194,854/year

The Nakamura petition was filed with an LCA certifying a prevailing wage at Level III ($157,830/year). Nakamura's actual compensation — which is expected to be confirmed from the transferred file as consistent with a senior-level signal integrity engineer's total compensation, likely in the range of $210,000 base salary plus approximately $55,000 in restricted stock units ("RSUs") for a total compensation of approximately $265,000 — substantially exceeds the Level IV prevailing wage. This premium compensation reflects the advanced nature of the position and the exceptional qualifications required of the individual performing the role.

The RFE response will reference the wage data to argue that Nakamura's compensation, which places the position well above the Level IV threshold, is indicative of a role that demands a high degree of specialization — a point that further supports the specialty occupation classification. An employer does not compensate an employee at more than double the Level I prevailing wage for a position that could be filled by an individual without a bachelor's degree in a specific engineering discipline.

D. Pillar 4: Comparable Position Data from Peer Semiconductor Companies

The fourth pillar addresses Criterion 2 of the regulatory test by demonstrating that the degree requirement for signal integrity engineering positions is common across the semiconductor and photonics industries.

1. Job Posting Evidence

Calderwood & Harkness will compile a collection of current and recent job postings for "Signal Integrity Engineer" and closely related positions (e.g., "SI/PI Engineer," "High-Speed Signal Integrity Engineer," "Signal and Power Integrity Engineer") from peer semiconductor and photonics companies. The postings will be drawn from the following sources:

• Major job boards (Indeed, Penmark Technologies, Westmark Health IT Jobs)

• Company career pages of major semiconductor, photonics, and data center interconnect companies

• Industry-specific job boards and professional association career centers (e.g., IEEE Job Site)

All comparable postings should demonstrate a minimum requirement of a Bachelor of Science degree in Electrical Engineering, Electronics Engineering, Physics, or a closely related field. Postings will be selected from companies of similar size, industry segment (semiconductor device manufacturing, photonics, data center interconnects, optical communications), and geographic market to ensure comparability with OWS.

The target is to compile eight (8) to twelve (12) comparable postings. Based on our prior experience with similar RFE responses, this number is sufficient to establish a clear industry pattern while remaining manageable for the adjudicating officer's review. Each posting will be printed in its entirety, with the relevant degree requirement highlighted or annotated for ease of reference.

2. Analysis Framework

In addition to the raw job postings, the RFE response will include a comparative analysis chart summarizing the key data from each posting. The chart will include the following columns:

This chart will provide a clear, at-a-glance demonstration that the degree requirement is universal and specific across the industry — not merely a general bachelor's degree, but a degree in a specific engineering or physical science discipline. The chart will be accompanied by a narrative analysis highlighting the consistency of the degree requirement across all postings and noting any additional observations (e.g., many postings prefer or require a master's degree or Ph.D., further underscoring the advanced nature of the occupation).

Where company names are publicly available through the job postings (which is the case for the vast majority of postings on major job boards and company career pages), company names will be included in the analysis. Anonymization is not expected to be necessary, as the data is drawn from public sources.

3. OWS Internal Hiring History

To address Criterion 3 — which asks whether the employer normally requires a degree for the position — Calderwood & Harkness will request from Samantha Kowalski, Director of Human Resources, and Rajesh Anand, Immigration Program Manager, the educational credentials of all current and former Signal Integrity Engineers at OWS.

This data will be used to demonstrate that OWS has consistently required and hired individuals with relevant bachelor's or advanced degrees for the Signal Integrity Engineer position. The analysis will show the degree field, degree level, and conferring institution for each hire, establishing a clear pattern of degree-based hiring.

If Nakamura is or has been the only Signal Integrity Engineer at OWS — which is possible given the company's size and the specialized nature of the role — the analysis will be expanded to include related positions within OWS's engineering organization, such as RF Design Engineers, Analog IC Designers, Photonics Engineers, and Packaging Engineers. By showing that OWS requires a relevant bachelor's degree or higher for all comparable engineering positions within its photonics and semiconductor engineering teams, the company can demonstrate that its degree requirement for the Signal Integrity Engineer position is part of a consistent, enterprise-wide practice — not an ad hoc requirement created for purposes of the H-1B petition.

Rajesh Anand and Samantha Kowalski will be asked to compile and provide this data within five (5) business days of the file transfer completion. Calderwood & Harkness will prepare the analysis in a format suitable for inclusion as an exhibit to the RFE response (Exhibit I).

V. EVIDENTIARY PACKAGE — RECOMMENDED EXHIBITS

I. EXECUTIVE SUMMARY
Calderwood & Harkness LLP ("Calderwood & Harkness" or the "Firm") has been engaged by Optiwave Semiconductor Corp. ("OWS" or the "Petitioner") effective May 20, 2025, to assume management of the company's employment-based immigration program, including all pending visa petitions and related matters previously handled by Whitfield & Parekh LLP ("Whitfield & Parekh" or "Prior Counsel"), whose engagement with OWS concluded on April 30, 2025. The transition of counsel was driven by firm capacity constraints at Whitfield & Parekh and the broader consolidation of outside legal services across the portfolio companies of Crestline Ventures Fund IV, LP, OWS's majority shareholder.
This memorandum addresses the most time-sensitive of the matters currently in transition: a pending Request for Evidence ("RFE") issued by U.S. Citizenship and Immigration Services ("USCIS") in connection with the H-1B extension petition filed on behalf of Takeshi Nakamura ("Nakamura" or the "Beneficiary"), a Signal Integrity Engineer employed at OWS's San Jose headquarters. The underlying extension petition, Form I-129 with H-1B classification supplement, was filed on March 15, 2025 by Kavita Parekh of Whitfield & Parekh LLP. USCIS subsequently issued an RFE challenging whether the Signal Integrity Engineer position qualifies as a "specialty occupation" within the meaning of section 214(i)(1) of the Immigration and Nationality Act ("INA") and 8 C.F.R. § 214.2(h)(4)(ii).
The RFE focuses on the position's classification under Standard Occupational Classification ("SOC") Code 17-2072 (Electronics Engineers, Except Computer). Specifically, USCIS has questioned whether the position requires a minimum of a bachelor's degree or higher in a specific specialty directly related to the position as a normal minimum requirement for entry, whether such a degree requirement is common across the industry for parallel positions, and whether the duties are sufficiently specialized to require the theoretical and practical application of a body of highly specialized knowledge. These inquiries are consistent with the types of scrutiny that USCIS has applied to engineering positions with increasing frequency since the issuance of revised adjudication guidance beginning in 2017.
From a timing perspective, Nakamura's I-94 Arrival/Departure Record expired on May 31, 2025. However, because the extension petition was timely filed on March 15, 2025 — more than two months prior to the I-94 expiration — Nakamura is authorized to continue employment with OWS in the same position and under the same terms for up to 240 days beyond the I-94 expiration date, pursuant to 8 C.F.R. § 214.2(h)(2)(i)(H). This means Nakamura's employment authorization under the 240-day rule extends through approximately January 25, 2026, provided the extension petition remains pending and is not denied during that period.
Urgency: The exact date of the RFE issuance and the corresponding response deadline have not yet been confirmed by Calderwood & Harkness, as the complete case file is still in transit from Whitfield & Parekh. The target completion date for the file transfer is June 15, 2025. Standard RFE response windows are either 60 or 87 calendar days from the date of issuance. The precise deadline is critical, and confirming it is the Firm's most immediate priority. Failure to respond within the prescribed period would result in adjudication of the petition based on the existing record, which, given the specialty occupation challenge, would likely result in denial.
The recommended response strategy is organized around four pillars:
(1) Regulatory analysis of the specialty occupation criteria and position-specific argumentation demonstrating that the Signal Integrity Engineer position satisfies each of the four alternative regulatory criteria set forth in 8 C.F.R. § 214.2(h)(4)(ii);
(2) Industry expert declarations from semiconductor and photonics professionals — including academic experts and senior practitioners — attesting to the universal degree requirement for signal integrity engineering positions in the semiconductor industry;
(3) Analysis of the Department of Labor ("DOL") Occupational Outlook Handbook ("OOH") and the O*NET OnLine database for SOC 17-2072, confirming the bachelor's degree requirement for the occupation; and
(4) Comparable position data from peer semiconductor employers, including a compilation of current and recent job postings and an analysis of OWS's own internal hiring history, demonstrating the industry-wide and employer-specific consistency of the degree requirement.
Additionally, Nakamura has a pending EB-1B outstanding researcher petition with a priority date of September 10, 2022. While the H-1B specialty occupation analysis is position-focused rather than beneficiary-focused, Nakamura's extraordinary qualifications — which formed the basis of the EB-1B filing — underscore the highly specialized nature of the work he performs at OWS and the level of expertise that OWS requires for this position. This fact can and should be leveraged in the RFE response.
Calderwood & Harkness believes that a comprehensive, evidence-rich response addressing each of USCIS's specific concerns should result in approval of the extension petition. The balance of this memorandum sets forth the factual background, legal framework, detailed response strategy, recommended evidentiary package, risk assessment, action items, timeline, and budget estimate for the RFE response.
II. BACKGROUND
A. Beneficiary Profile — Takeshi Nakamura
Takeshi Nakamura is a Japanese national currently employed by OWS as a Signal Integrity Engineer at the company's headquarters in San Jose, California. The following summarizes the key facts and immigration history relevant to the pending RFE:
Nakamura's educational credentials and publication record are central to the EB-1B outstanding researcher petition and will be confirmed upon receipt of the complete file from Whitfield & Parekh. Based on the information available to Calderwood & Harkness from OWS's internal records and preliminary discussions with Rajesh Anand, Nakamura holds at minimum a bachelor's degree in electrical engineering or a closely related discipline and has published extensively in peer-reviewed journals in the signal integrity and photonics fields. His EB-1B filing indicates recognition as an outstanding researcher with international standing in his area of expertise. These credentials substantially exceed the minimum requirements for the Signal Integrity Engineer position and serve as additional evidence that the position demands a high level of specialized knowledge.
Nakamura has been employed by OWS since June 1, 2022, when his current H-1B validity period commenced. Prior to his employment with OWS, it is understood that Nakamura held H-1B status with a prior employer, although the details of his earlier immigration history will be confirmed from the transferred file. His continuous maintenance of H-1B status and timely filing of the extension petition are essential predicates for the 240-day employment authorization rule that currently governs his work authorization.
B. Petitioner Profile — Optiwave Semiconductor Corp.
Optiwave Semiconductor Corp. is a Delaware corporation qualified to do business in California, Texas, and Oregon. OWS was founded on March 14, 2017 and is headquartered at 4820 Veltrano Parkway, Suite 300, San Jose, California 95134. The company's Federal Employer Identification Number ("FEIN") is 82-4931076, and it operates under NAICS Code 334413 (Semiconductor and Related Device Manufacturing).
OWS specializes in the design and fabrication of photonic integrated circuits ("PICs") for data center interconnect applications. The company develops advanced silicon photonic and indium phosphide-based transceivers and related optical components that enable high-speed data transmission within and between cloud computing data centers. OWS's products operate at the frontier of optical communications technology, requiring its engineering workforce to possess deep expertise in semiconductor physics, electromagnetic theory, photonics, analog and mixed-signal circuit design, and related disciplines.
As of the date of this memorandum, OWS employs approximately 340 individuals across three offices and a remote workforce:
• San Jose, California (headquarters): approximately 210 employees
• Austin, Texas: approximately 65 employees
• Portland, Oregon: approximately 40 employees
• Remote personnel: approximately 25 employees
The company reported annual revenue of $187.4 million for fiscal year 2024, as reflected in its audited financial statements prepared by Pendleton Accounting Group LLP. OWS's majority shareholder is Crestline Ventures Fund IV, LP, which acquired a 62.4% equity stake in the company on September 15, 2022. The Crestline transaction brought OWS into a portfolio of growth-stage semiconductor and advanced technology companies, and it was Crestline's portfolio-wide consolidation of outside counsel that ultimately precipitated the transition from Whitfield & Parekh to Calderwood & Harkness.
OWS is enrolled in the E-Verify program (Company ID: 1487623) and is classified as an H-1B non-dependent employer. The company currently sponsors 14 H-1B workers out of its total workforce of approximately 340, representing 4.12% of its employee base. This figure is well below the 15% threshold that would trigger H-1B dependency requirements under INA § 212(n)(3) and the associated attestation obligations. OWS's non-dependent status simplifies certain aspects of the H-1B petition process and reduces the applicable compliance burdens.
The hiring manager and technical attestor for the Nakamura petition is Dr. Yun-Sheng Chen, Vice President of Engineering at OWS. Dr. Chen oversees the company's signal integrity, analog IC design, and photonics engineering teams, and he is directly responsible for defining the educational and technical qualifications required for engineering positions within his division. Dr. Chen's support letter will be a cornerstone of the RFE response, and his participation in identifying potential expert declarants will be essential.
Additional OWS personnel who will be involved in the RFE response effort include:
• Patricia Langford, General Counsel, who serves as the primary legal contact for the OWS engagement and who has authority to approve external legal expenditures and strategic decisions related to the company's immigration program.
• Rajesh Anand, Immigration Program Manager, who manages day-to-day immigration matters, coordinates with outside counsel, and interfaces with OWS's human resources department on immigration-related employment documentation.
• Samantha Kowalski, Director of Human Resources, who maintains employee records, including educational credentials and hiring data, and who will be responsible for providing the internal hiring history data needed for the RFE response.
C. Prior Counsel Transition
Whitfield & Parekh LLP, under the direction of Kavita Parekh, Partner, served as OWS's primary immigration counsel from June 1, 2019 through April 30, 2025. During this six-year engagement, Whitfield & Parekh handled OWS's full range of employment-based immigration matters, including H-1B petitions, PERM labor certifications, I-140 immigrant petitions, and related filings.
The transition from Whitfield & Parekh to Calderwood & Harkness was prompted by two concurrent factors. First, Whitfield & Parekh experienced significant capacity constraints beginning in late 2024, which resulted in delays in filing timelines and limited availability of senior attorneys for strategic consultations. Second, Crestline Ventures Fund IV, LP — OWS's majority shareholder — initiated a portfolio-wide consolidation of outside legal services in the first quarter of 2025, directing its portfolio companies to engage a smaller number of pre-approved law firms for specialized legal work, including immigration. Calderwood & Harkness was selected as one of three approved immigration counsel for Crestline portfolio companies, and OWS's engagement with the Firm commenced on May 20, 2025.
A formal file transfer request was submitted to Whitfield & Parekh on May 22, 2025. The target completion date for the transfer is June 15, 2025. The Nakamura RFE file is among three pending RFE matters being transferred to Calderwood & Harkness. The two other pending RFEs involve separate OWS employees and different adjudicatory issues, and they will be addressed in separate memoranda following file receipt and review.
It is imperative that Calderwood & Harkness obtain the exact RFE issuance date and response deadline for the Nakamura matter immediately upon receipt of the file — or, if possible, in advance of the full file transfer. Megan Chu and Tanya Benavides have been directed to contact Whitfield & Parekh to request, at minimum, a copy of the RFE notice itself, even before the remainder of the file is transferred, so that the response deadline can be confirmed and the response timeline can be finalized. Rajesh Anand has been separately asked to check whether OWS received a copy of the RFE notice directly from USCIS or from Whitfield & Parekh.
The original petition and all supporting materials filed by Whitfield & Parekh are under review and will be thoroughly analyzed by Calderwood & Harkness upon receipt. Where deficiencies in the original filing may have contributed to the issuance of the RFE, Calderwood & Harkness will supplement the record with additional evidence and argumentation. It is not unusual for an RFE to be issued where the initial filing, while competent, did not include sufficient granular evidence of the degree requirement's universality in the industry or detailed duty-to-coursework mapping — both of which will be central to our response strategy.
D. The RFE — Nature of the Challenge
USCIS issued a Request for Evidence challenging the specialty occupation classification of the Signal Integrity Engineer position at OWS. While the precise text of the RFE has not yet been reviewed by Calderwood & Harkness (pending file transfer), the nature of the challenge has been communicated by Rajesh Anand based on his discussions with Whitfield & Parekh and his review of a summary provided by Kavita Parekh prior to the engagement's conclusion. Based on this information and our extensive experience with specialty occupation RFEs in the engineering context, we anticipate that the RFE raises the following specific concerns:
(1) Whether the Signal Integrity Engineer position requires a minimum of a bachelor's degree or higher in a specific specialty directly related to the position as a normal minimum requirement for entry into the occupation;
(2) Whether the degree requirement is common across the industry for parallel positions among similar organizations, or, alternatively, whether the position is so complex or unique that it can be performed only by an individual with a degree;
(3) Whether the job duties described in the petition are sufficiently specialized to require the theoretical and practical application of a body of highly specialized knowledge; and
(4) Whether OWS can establish that it normally requires a bachelor's degree or its equivalent in a specific specialty for the Signal Integrity Engineer position.
These four areas of inquiry map directly to the four alternative regulatory criteria for specialty occupation classification under 8 C.F.R. § 214.2(h)(4)(ii), and the RFE response must systematically address each one. This type of RFE is consistent with the heightened scrutiny that USCIS has applied to engineering positions since the issuance of revised policy guidance in 2017 and in light of the adjudicatory framework established in Matter of Simeio Solutions, LLC, 26 I&N Dec. 542 (AAO 2015), which, while primarily addressing Labor Condition Application ("LCA") amendments for worksite changes, reflects USCIS's broader emphasis on strict compliance with the conditions of H-1B employment.
It is worth noting that specialty occupation RFEs for electronics engineering positions classified under SOC 17-2072 are less common than those issued for computer-related occupations (SOC 15-series codes), precisely because the DOL's own Occupational Outlook Handbook unambiguously states that a bachelor's degree in electrical engineering or a related engineering discipline is required for entry into the occupation. This fact provides a strong foundation for the RFE response, and the issuance of the RFE may reflect deficiencies in the evidentiary support provided with the original petition rather than any genuine ambiguity about the occupation's specialty nature.
III. LEGAL FRAMEWORK — SPECIALTY OCCUPATION CLASSIFICATION
A. Statutory Standard — INA § 214(i)(1)
Section 214(i)(1) of the Immigration and Nationality Act defines a "specialty occupation" as an occupation that requires:
(A) theoretical and practical application of a body of highly specialized knowledge, and
(B) attainment of a bachelor's or higher degree in the specific specialty (or its equivalent) as a minimum for entry into the occupation in the United States.
This statutory definition establishes a two-part test. First, the position must involve the theoretical and practical application of a body of "highly specialized knowledge" — that is, the work cannot consist merely of routine tasks or the mechanical application of established procedures, but must demand the application of specialized theoretical principles and advanced practical expertise. Second, the position must require, as a minimum for entry, the attainment of a bachelor's degree or higher in a "specific specialty" directly related to the position. The specificity requirement is critical: a general bachelor's degree in any field does not satisfy the statute. Rather, the degree must be in a specific academic discipline — such as electrical engineering, electronics engineering, or physics — that is directly related to the duties of the position.
For the Signal Integrity Engineer position at OWS, both prongs of this statutory test are readily satisfied. The position involves the application of advanced principles of electromagnetic theory, semiconductor physics, transmission line theory, and signal processing — all of which constitute a body of highly specialized knowledge that is the subject of specific academic programs in electrical and electronics engineering. Moreover, as demonstrated by the DOL's Occupational Outlook Handbook and the consistent hiring practices of OWS and its industry peers, a bachelor's degree in electrical engineering, electronics engineering, physics, or a closely related discipline is the universally recognized minimum qualification for entry into signal integrity engineering positions.
B. Regulatory Criteria — 8 C.F.R. § 214.2(h)(4)(ii)
The implementing regulations at 8 C.F.R. § 214.2(h)(4)(ii) provide that a petitioner may establish specialty occupation status by demonstrating that the position meets at least one of four alternative criteria. While a petitioner need only satisfy one criterion for approval, a robust RFE response should address all four to maximize the probability of approval. The four criteria are as follows:
Criterion 1: A baccalaureate or higher degree or its equivalent is normally the minimum requirement for entry into the particular position.
This criterion focuses on the occupation as a whole. The petitioner must demonstrate that the normal minimum educational requirement for the position — not merely the employer's preferred or ideal qualification, but the standard minimum requirement recognized across the field — is a bachelor's degree or higher in a specific specialty. The word "normally" has been the subject of extensive litigation and adjudicatory guidance. USCIS Policy Memorandum PM-602-0142.1 (discussed below) clarified that "normally" does not require that a degree is always required, but rather that it is the typical or standard minimum requirement for entry. This criterion is most effectively addressed through reference to the DOL Occupational Outlook Handbook, O*NET data, and industry-wide hiring practices.
Criterion 2: The degree requirement is common to the industry in parallel positions among similar organizations, or, in the alternative, the particular position is so complex or unique that it can be performed only by an individual with a degree.
This criterion contains two alternative sub-tests. Under the first sub-test, the petitioner must show that the degree requirement is common across the industry for parallel positions at similar organizations — a showing that is effectively made through a compilation of comparable job postings from peer employers. Under the second sub-test, the petitioner may alternatively show that the position itself is so complex or unique that only a degreed individual could perform the duties. For a signal integrity engineering position in the semiconductor industry, both sub-tests are satisfied, but the first sub-test is more straightforward to document.
Criterion 3: The employer normally requires a degree or its equivalent for the position.
This criterion is employer-specific rather than industry-wide. The petitioner must demonstrate its own established practice of requiring a bachelor's degree in a specific specialty for the position in question. This showing is made through the employer's internal hiring records, human resources policies, and attestations from management personnel. If OWS has consistently required a bachelor's degree in electrical engineering, electronics engineering, or physics for all signal integrity engineering hires, this criterion is directly satisfied.
Criterion 4: The nature of the specific duties is so specialized and complex that knowledge required to perform them is usually associated with the attainment of a baccalaureate or higher degree.
This criterion focuses on the duties themselves rather than the occupation in the abstract or the employer's historical practices. The petitioner must demonstrate that the specific duties assigned to the beneficiary are sufficiently specialized and complex that the knowledge necessary to perform them is typically acquired through a bachelor's or higher degree program in a specific discipline. This criterion requires a granular analysis of job duties and a mapping of those duties to the curriculum of relevant degree programs.
Our response strategy addresses all four criteria, with the strongest emphasis on Criteria 1, 2, and 4, as these are the criteria most likely to be questioned by the adjudicating officer and the criteria for which the available evidence is most robust.
C. Relevant Precedent and Guidance
Several key sources of administrative precedent and policy guidance inform the RFE response strategy:
Matter of Simeio Solutions, LLC, 26 I&N Dec. 542 (AAO 2015). Although this precedent decision primarily addresses the requirement for an amended LCA when there is a material change in the terms and conditions of H-1B employment — particularly changes in worksite — it has broader implications for H-1B adjudication. Simeio Solutions reflects USCIS's heightened emphasis on ensuring that the terms of H-1B employment are precisely documented and consistently maintained. In the context of the Nakamura RFE response, Simeio Solutions underscores the importance of demonstrating that the current LCA on file is fully compliant and that the position as described is consistent with the certified LCA terms, including the SOC classification, prevailing wage level, and worksite location.
USCIS Policy Memorandum PM-602-0142.1 (Rescission of Prior Restrictive Guidance). This policy memorandum, issued in 2020, rescinded earlier memoranda that had imposed restrictive interpretive standards on specialty occupation adjudications. The rescinded guidance had been criticized by immigration practitioners, industry groups, and federal courts for, among other things, requiring petitioners to demonstrate that a degree is always required for the occupation — a standard that exceeded the regulatory text of "normally." PM-602-0142.1 restored the pre-2017 adjudicatory framework and confirmed that the "normally" standard under Criterion 1 does not demand absolute universality of the degree requirement; rather, it requires that a bachelor's degree in a specific specialty is the standard or typical minimum requirement for entry into the occupation. This rescission is directly supportive of the Nakamura RFE response, particularly given that the OOH for SOC 17-2072 expressly states a degree requirement.
Administrative Appeals Office Decisions — Engineering Positions. The AAO has sustained numerous appeals and affirmed specialty occupation classification for engineering positions in the semiconductor, electronics, and related industries. While AAO non-precedent decisions are not binding, they reflect the agency's consistent recognition that electrical and electronics engineering positions — particularly those involving advanced signal integrity, electromagnetic simulation, and semiconductor device design — inherently require a bachelor's degree in a specific engineering discipline. We will identify and cite relevant AAO decisions in the cover letter accompanying the RFE response.
Federal Court Decisions. Federal district courts have repeatedly reinforced the principle that USCIS must give appropriate deference to the employer's reasonable business judgment regarding degree requirements where that judgment is supported by evidence. Courts have vacated USCIS denials of H-1B petitions where the agency substituted its own assessment of position requirements for the employer's documented, evidence-backed determination. These decisions are particularly relevant where, as here, the employer (OWS) has a consistent track record of requiring a specific degree for the position, the DOL's own publications confirm the degree requirement, and the position involves highly specialized technical duties that manifestly require degree-level training.
IV. RESPONSE STRATEGY — FOUR PILLARS
The RFE response will be organized around four complementary evidentiary pillars, each designed to address one or more of the four regulatory criteria and to respond to the specific concerns raised in the RFE. Together, these pillars will present a comprehensive, multi-layered case for specialty occupation classification that addresses the issue from regulatory, academic, industry, and employer-specific perspectives.
A. Pillar 1: Regulatory Analysis and Position-Specific Argumentation
The first pillar focuses on the legal and factual analysis of the Signal Integrity Engineer position itself, demonstrating through detailed examination of the job duties, the minimum degree requirement, and the nexus between the two that the position satisfies the statutory and regulatory definition of a specialty occupation.
1. Detailed Job Duties Analysis
The Signal Integrity Engineer position at OWS is a highly specialized technical role situated within the company's photonic integrated circuit ("PIC") engineering division. Nakamura's duties encompass the full lifecycle of signal integrity engineering for advanced optical transceiver platforms, from initial design and simulation through characterization and validation. The principal duties of the position include the following:
• Analysis of high-speed signal propagation in photonic integrated circuits. Nakamura is responsible for analyzing the behavior of electrical and optical signals as they propagate through PIC structures, including modeling signal attenuation, dispersion, and reflection at material interfaces and interconnect junctions. This work requires the application of Maxwell's equations and electromagnetic wave theory to complex, multi-layered semiconductor structures operating at data rates of 100 Gbps and above.
• Electromagnetic simulation and modeling of interconnect structures. Nakamura uses commercial electromagnetic simulation tools — including Crowne Albany Data Systems, Tarrant Services Inc., and Beaumont Systems — to model the electromagnetic behavior of chip-to-package and package-to-board interconnect structures. This simulation work requires a deep understanding of computational electromagnetics, finite element analysis, and the physical properties of semiconductor materials, dielectrics, and metallization layers.
• Design of signal conditioning circuits for data center optical transceivers. Nakamura participates in the design of equalization, pre-emphasis, and de-emphasis circuits that optimize signal quality for data center interconnect applications. This work requires knowledge of high-frequency analog circuit design, linear systems theory, and digital signal processing techniques applied to serial data communication channels.
• Characterization of crosstalk, jitter, and insertion loss in PIC platforms. Nakamura conducts laboratory measurements and data analysis to characterize key signal integrity metrics, including far-end and near-end crosstalk, deterministic and random jitter components, and frequency-dependent insertion loss across the operating bandwidth of OWS's transceiver products. This work requires proficiency in vector network analyzer measurements, time-domain reflectometry, eye diagram analysis, and S-parameter extraction and interpretation.
• Collaboration with analog IC design and packaging engineering teams. Nakamura works closely with OWS's analog integrated circuit designers and packaging engineers to ensure that signal integrity requirements are met throughout the design process, from initial circuit specification through final package design and board-level integration. This collaboration requires the ability to translate signal integrity analysis results into actionable design constraints and to evaluate design trade-offs across multiple engineering disciplines.
A detailed percentage breakdown of Nakamura's time allocation across these and related duties will be prepared as an exhibit to the RFE response (Exhibit B), following the standard format for duty description exhibits used in H-1B specialty occupation filings. The percentage breakdown will be reviewed and attested to by Dr. Yun-Sheng Chen, VP of Engineering, who has direct supervisory responsibility for Nakamura's work.
The critical point to be emphasized in the RFE response is that each of these duties requires the application of advanced theoretical knowledge drawn from specific academic disciplines — electromagnetic theory, semiconductor physics, analog circuit design, and digital signal processing — that are taught at the bachelor's and graduate levels in accredited programs in electrical engineering, electronics engineering, and physics. These are not duties that can be performed by individuals with general education or through on-the-job training alone. The theoretical foundations are prerequisites, not supplements, to the practical skills applied in the role.
2. Minimum Degree Requirement Attestation
OWS requires a minimum of a Bachelor of Science degree in Electrical Engineering, Electronics Engineering, Physics, or a closely related field for the Signal Integrity Engineer position. This requirement is not merely a preference or aspiration; it is an absolute minimum qualification that OWS has consistently applied in its hiring for this position and for all comparable engineering positions within its photonics and signal integrity engineering teams.
The RFE response will include a detailed support letter from Dr. Yun-Sheng Chen, Vice President of Engineering, on OWS letterhead (Exhibit A). Dr. Chen's letter will attest to the following:
• OWS has established, and consistently enforces, a minimum educational requirement of a B.S. degree in Electrical Engineering, Electronics Engineering, Physics, or a closely related field for all Signal Integrity Engineer positions;
• This degree requirement reflects OWS's assessment that the duties of the Signal Integrity Engineer position cannot be competently performed without the foundational theoretical knowledge acquired through a structured degree program in the specified disciplines;
• OWS has never hired a Signal Integrity Engineer — or, to the extent applicable, any engineer in a comparable role within the signal integrity or photonics engineering teams — without at minimum a bachelor's degree in one of the specified disciplines;
• The degree requirement is consistent with the requirements applied by OWS's competitors and peers in the semiconductor and photonics industries; and
• Nakamura himself meets and substantially exceeds the minimum degree requirement, as evidenced by his academic credentials and his recognition as an outstanding researcher in the field (as reflected in his pending EB-1B petition).
Dr. Chen's letter will be drafted by Calderwood & Harkness (Derek Okonkwo, working associate) in close consultation with Dr. Chen and Rajesh Anand, to ensure technical accuracy and consistency with all other documentation in the record. The letter will be provided to Dr. Chen for review, revision as necessary, and execution on OWS letterhead.
3. Nexus Between Degree and Duties
A central component of the Pillar 1 analysis is a detailed mapping of specific job duties to specific university coursework, demonstrating that the knowledge required to perform the Signal Integrity Engineer duties is acquired through the structured curriculum of a bachelor's degree program in the relevant engineering or physical science disciplines. This duty-to-coursework mapping serves to rebut any argument that the position's knowledge requirements could be met through general education, unrelated degree programs, or informal on-the-job training.
The mapping will correlate each principal duty with specific courses that are standard components of accredited B.S. programs in Electrical Engineering, including but not limited to:
This table will be expanded and refined in the RFE response cover letter and in the supporting exhibits. Copies of relevant course syllabi from accredited B.S. programs in Electrical Engineering will be submitted as Exhibit L to further substantiate the nexus between the degree requirement and the position duties.
The argumentation will emphasize that the knowledge required for the Signal Integrity Engineer position is not merely "useful" or "helpful" but is essential — and that this essential knowledge is acquired through the specific, multi-year curriculum of a bachelor's degree program in the relevant engineering disciplines. An individual without this educational foundation would lack the theoretical framework necessary to perform even the most basic duties of the position, such as interpreting S-parameter data, setting up electromagnetic simulations, or designing equalization circuits for high-speed serial links.
B. Pillar 2: Industry Expert Declarations
The second pillar involves the procurement and submission of expert declarations from qualified individuals in the semiconductor and signal integrity engineering fields. Expert declarations serve as independent, third-party validation that the degree requirement is inherent to the occupation and is not merely an idiosyncratic preference of the petitioning employer.
1. Identification of Expert Declarants
Calderwood & Harkness recommends obtaining two to three expert declarations from individuals representing a cross-section of the signal integrity and semiconductor engineering community. The ideal declarant panel would include:
(a) Academic expert(s) in electrical engineering / signal integrity. Professors at research universities with established semiconductor engineering programs are particularly well-positioned to attest to the educational requirements of signal integrity engineering positions. Such declarants can speak authoritatively to the curriculum content of B.S. programs in electrical engineering, the theoretical knowledge that students acquire through these programs, and the direct applicability of that knowledge to signal integrity work in the semiconductor industry. Potential institutions include Stanford University, UC Berkeley, Georgia Institute of Technology, Purdue University, and the University of Michigan — all of which have leading programs in semiconductor device physics, electromagnetic theory, and signal integrity.
(b) Senior industry practitioners at peer semiconductor companies. Declarations from senior engineers or engineering managers at companies comparable to OWS — including other photonics, semiconductor, and data center interconnect firms — would demonstrate that the degree requirement is common across the industry for parallel positions. These declarants can attest from their own hiring experience and professional knowledge that signal integrity engineering positions in the semiconductor industry universally require a B.S. degree in electrical engineering, electronics engineering, or physics. Names of potential declarants will be identified with the assistance of Dr. Yun-Sheng Chen, who maintains professional relationships with counterparts at peer companies through industry conferences, IEEE activities, and professional networks.
(c) Professional association representatives. A declaration from a representative of a relevant professional organization — such as the Institute of Electrical and Electronics Engineers ("IEEE"), the Signal Integrity Society, the Optical Society of America, or the Semiconductor Industry Association — would provide additional institutional validation of the degree requirement. Alternatively, a third industry expert or academic declarant may be substituted if a professional association declaration proves difficult to obtain within the available timeframe.
2. Content of Expert Declarations
Each expert declaration will be drafted by Calderwood & Harkness (Megan Chu, associate) and will be submitted to the declarant for review, revision, and execution under penalty of perjury. The declarations will be tailored to each declarant's specific expertise and professional background, but all declarations should attest to the following core points:
(a) Signal Integrity Engineer positions in the semiconductor industry universally require, as a minimum educational qualification, a Bachelor of Science degree in Electrical Engineering, Electronics Engineering, or Physics (or a closely related discipline such as Applied Physics or Computer Engineering with an emphasis in electromagnetics);
(b) The work performed by a Signal Integrity Engineer — including electromagnetic simulation, high-speed signal analysis, crosstalk and jitter characterization, and signal conditioning circuit design — cannot be competently performed by individuals who do not possess such a degree;
(c) The specific duties described in the OWS Signal Integrity Engineer position are consistent with the duties performed by degree-holding signal integrity engineers throughout the semiconductor and photonics industries;
(d) The position involves the theoretical and practical application of a highly specialized body of knowledge, including electromagnetic theory, transmission line theory, semiconductor device physics, and high-frequency circuit design; and
(e) The educational qualifications required for the position are acquired through the structured curriculum of an accredited bachelor's degree program in the relevant disciplines and cannot be acquired through general education, unrelated degree programs, or on-the-job training alone.
In addition to these core attestations, each declaration should reference specific technical competencies that are hallmarks of the signal integrity engineering profession and that require degree-level training:
• S-parameter analysis and extraction
• Eye diagram interpretation and compliance testing
• Channel modeling and simulation using industry-standard tools (Crowne Albany Data Systems, Tarrant Services Inc., Beaumont Systems, Marlowe Services Inc.)
• Electromagnetic interference ("EMI") and electromagnetic compatibility ("EMC") mitigation
• Time-domain reflectometry ("TDR") measurements
• Power integrity analysis and simultaneous switching noise ("SSN") evaluation
• Impedance matching and controlled impedance design for multi-gigabit serial links
The inclusion of these specific technical competencies serves to demonstrate the depth and specificity of the knowledge required for the position, reinforcing the argument that a general bachelor's degree — or a degree in an unrelated field — would be wholly insufficient to prepare an individual for signal integrity work.
3. Timeline for Securing Declarations
Securing expert declarations is typically the most time-intensive element of an RFE response, as it requires identifying willing declarants, coordinating with their schedules, drafting declarations tailored to their expertise, and allowing sufficient time for review and execution. The following timeline is recommended:
• Identification and outreach: Potential declarants should be identified and approached within five (5) business days of the completion of the file transfer from Whitfield & Parekh. Dr. Lena Marchetti will take the lead on academic expert outreach, leveraging her professional network in the engineering education community. Dr. Yun-Sheng Chen will be asked to identify appropriate industry contacts for practitioner declarations.
• Drafting: Allow ten (10) to fifteen (15) business days for declaration drafting, review by the declarant, revisions, and final execution. Megan Chu will be responsible for preparing initial drafts of all declarations.
• Coordination: Dr. Yun-Sheng Chen and Rajesh Anand will facilitate introductions between Calderwood & Harkness and potential industry declarants. All communications with declarants will be managed by Calderwood & Harkness to ensure consistency and quality of the declarations.
Given the importance of the declarations to the overall RFE response and the lead time required, the declarant identification and outreach process should commence as soon as practicable, even before the complete file transfer is finalized, if the RFE response deadline permits.
C. Pillar 3: DOL Occupational Outlook Handbook and O*NET Analysis
The third pillar relies on the U.S. Department of Labor's own publications — the Occupational Outlook Handbook and the O*NET OnLine database — to establish that the Signal Integrity Engineer position, classified under SOC Code 17-2072 (Electronics Engineers, Except Computer), is recognized by the federal government as requiring a bachelor's degree in a specific engineering discipline.
1. OOH Entry for Electronics Engineers, Except Computer (SOC 17-2072)
The DOL Occupational Outlook Handbook is the primary reference source used by USCIS adjudicators in evaluating specialty occupation claims, and it is often the single most persuasive piece of evidence in an RFE response. The OOH entry for Electronics Engineers, Except Computer expressly states that electronics engineers "need a bachelor's degree in electrical engineering, electronics engineering, or a related engineering field." This language is direct and unambiguous: the OOH identifies a bachelor's degree in a specific engineering discipline as the standard educational requirement for entry into the occupation.
The RFE response will present relevant excerpts from the OOH entry for SOC 17-2072, including:
• Education requirements section: The OOH's statement that a bachelor's degree in electrical engineering, electronics engineering, or a related engineering field is required for entry-level positions. This directly supports Criterion 1 of the regulatory test, which asks whether a baccalaureate degree is "normally the minimum requirement for entry into the particular position."
• Job duties description: The OOH describes the work of electronics engineers as involving the design, development, and testing of electronic components and systems, including communications systems, sensors, and electronic circuits. The description maps directly to Nakamura's signal integrity duties at OWS, which center on the design, simulation, and characterization of electronic and photonic components for data center communication systems.
• Work environment section: The OOH describes the work environments typical for electronics engineers, including laboratories, offices, and manufacturing facilities — all consistent with Nakamura's work environment at OWS.
The RFE response will emphasize that USCIS's own adjudication guidance identifies the OOH as a relevant source for determining whether an occupation normally requires a bachelor's degree in a specific specialty. Where the OOH expressly states a degree requirement, as it does for SOC 17-2072, USCIS should give that determination substantial weight in its adjudication.
2. O*NET Profile for SOC 17-2072
The ONET OnLine database, also maintained by the DOL, provides detailed occupational information that supplements the OOH. The ONET profile for SOC 17-2072 will be used to reinforce the OOH's degree requirement and to provide additional granular data on the knowledge, skills, and abilities required for the occupation.
Key O*NET data points to be cited in the RFE response include:
• Job Zone classification: SOC 17-2072 is classified as Job Zone 4 ("Considerable Preparation Needed") or Job Zone 5 ("Extensive Preparation Needed"), depending on the specific edition and subcategory. Both classifications indicate that the occupation requires significant formal educational preparation, typically including a bachelor's degree or higher.
• Specific Vocational Preparation ("SVP") range: The SVP range for the occupation indicates the amount of time required to learn the techniques, acquire the information, and develop the facility needed for average performance. For electronics engineers, the SVP range is consistent with the attainment of a bachelor's degree.
• Knowledge, skills, and abilities ("KSA") profile: The O*NET KSA profile for SOC 17-2072 identifies critical knowledge domains (e.g., engineering and technology, physics, mathematics, computers and electronics, design), essential skills (e.g., complex problem solving, critical thinking, systems analysis, programming), and required abilities (e.g., deductive reasoning, mathematical reasoning, information ordering). The RFE response will cross-reference this KSA profile with the specific duties and qualifications of the Signal Integrity Engineer position at OWS to demonstrate alignment.
• Education data: O*NET collects and reports data on the educational attainment of workers in each occupation. For SOC 17-2072, the data consistently shows that an overwhelming percentage of workers hold a bachelor's degree or higher — typically exceeding 85-90%. This empirical data further supports the conclusion that a bachelor's degree is the normal minimum requirement for entry into the occupation.
3. Bureau of Labor Statistics Wage Data
The Bureau of Labor Statistics ("BLS") prevailing wage data for SOC 17-2072 in the relevant Metropolitan Statistical Area provides additional context for the specialty occupation analysis. While wage data is not, by itself, dispositive of specialty occupation status, it provides corroborating evidence of the position's level of specialization and the qualifications required.
For the San Jose-Sunnyvale-Santa Clara, CA MSA, the prevailing wage levels for SOC 17-2072 (Electronics Engineers, Except Computer) are approximately:
• Level I (entry-level): approximately $120,806/year
• Level II: approximately $139,318/year
• Level III: approximately $157,830/year
• Level IV (fully competent): approximately $194,854/year
The Nakamura petition was filed with an LCA certifying a prevailing wage at Level III ($157,830/year). Nakamura's actual compensation — which is expected to be confirmed from the transferred file as consistent with a senior-level signal integrity engineer's total compensation, likely in the range of $210,000 base salary plus approximately $55,000 in restricted stock units ("RSUs") for a total compensation of approximately $265,000 — substantially exceeds the Level IV prevailing wage. This premium compensation reflects the advanced nature of the position and the exceptional qualifications required of the individual performing the role.
The RFE response will reference the wage data to argue that Nakamura's compensation, which places the position well above the Level IV threshold, is indicative of a role that demands a high degree of specialization — a point that further supports the specialty occupation classification. An employer does not compensate an employee at more than double the Level I prevailing wage for a position that could be filled by an individual without a bachelor's degree in a specific engineering discipline.
D. Pillar 4: Comparable Position Data from Peer Semiconductor Companies
The fourth pillar addresses Criterion 2 of the regulatory test by demonstrating that the degree requirement for signal integrity engineering positions is common across the semiconductor and photonics industries.
1. Job Posting Evidence
Calderwood & Harkness will compile a collection of current and recent job postings for "Signal Integrity Engineer" and closely related positions (e.g., "SI/PI Engineer," "High-Speed Signal Integrity Engineer," "Signal and Power Integrity Engineer") from peer semiconductor and photonics companies. The postings will be drawn from the following sources:
• Major job boards (Indeed, Penmark Technologies, Westmark Health IT Jobs)
• Company career pages of major semiconductor, photonics, and data center interconnect companies
• Industry-specific job boards and professional association career centers (e.g., IEEE Job Site)
All comparable postings should demonstrate a minimum requirement of a Bachelor of Science degree in Electrical Engineering, Electronics Engineering, Physics, or a closely related field. Postings will be selected from companies of similar size, industry segment (semiconductor device manufacturing, photonics, data center interconnects, optical communications), and geographic market to ensure comparability with OWS.
The target is to compile eight (8) to twelve (12) comparable postings. Based on our prior experience with similar RFE responses, this number is sufficient to establish a clear industry pattern while remaining manageable for the adjudicating officer's review. Each posting will be printed in its entirety, with the relevant degree requirement highlighted or annotated for ease of reference.
2. Analysis Framework
In addition to the raw job postings, the RFE response will include a comparative analysis chart summarizing the key data from each posting. The chart will include the following columns:
This chart will provide a clear, at-a-glance demonstration that the degree requirement is universal and specific across the industry — not merely a general bachelor's degree, but a degree in a specific engineering or physical science discipline. The chart will be accompanied by a narrative analysis highlighting the consistency of the degree requirement across all postings and noting any additional observations (e.g., many postings prefer or require a master's degree or Ph.D., further underscoring the advanced nature of the occupation).
Where company names are publicly available through the job postings (which is the case for the vast majority of postings on major job boards and company career pages), company names will be included in the analysis. Anonymization is not expected to be necessary, as the data is drawn from public sources.
3. OWS Internal Hiring History
To address Criterion 3 — which asks whether the employer normally requires a degree for the position — Calderwood & Harkness will request from Samantha Kowalski, Director of Human Resources, and Rajesh Anand, Immigration Program Manager, the educational credentials of all current and former Signal Integrity Engineers at OWS.
This data will be used to demonstrate that OWS has consistently required and hired individuals with relevant bachelor's or advanced degrees for the Signal Integrity Engineer position. The analysis will show the degree field, degree level, and conferring institution for each hire, establishing a clear pattern of degree-based hiring.
If Nakamura is or has been the only Signal Integrity Engineer at OWS — which is possible given the company's size and the specialized nature of the role — the analysis will be expanded to include related positions within OWS's engineering organization, such as RF Design Engineers, Analog IC Designers, Photonics Engineers, and Packaging Engineers. By showing that OWS requires a relevant bachelor's degree or higher for all comparable engineering positions within its photonics and semiconductor engineering teams, the company can demonstrate that its degree requirement for the Signal Integrity Engineer position is part of a consistent, enterprise-wide practice — not an ad hoc requirement created for purposes of the H-1B petition.
Rajesh Anand and Samantha Kowalski will be asked to compile and provide this data within five (5) business days of the file transfer completion. Calderwood & Harkness will prepare the analysis in a format suitable for inclusion as an exhibit to the RFE response (Exhibit I).
