Evidence Building
How to Use Department of Labor Wage Data to Frame O-1A High Salary Evidence
BLS OEWS wage data is the most defensible public benchmark for O-1A high salary comparisons, but using it correctly requires selecting the right SOC code, the right geographic scope, and the right percentile argument. This guide explains the mechanics of building a high salary exhibit that withstands USCIS scrutiny.
The criterion and OEWS wage benchmarks
The O-1A high salary criterion at 8 C.F.R. § 214.2(o)(3)(iii)(B)(8) requires the petitioner to command a salary or other remuneration for services that is high in relation to others in the field. The Bureau of Labor Statistics Occupational Employment and Wage Statistics program—known as OEWS, formerly OES—is the most widely cited public source for satisfying this requirement. OEWS covers approximately 830 occupations across the U.S. economy, organized by Standard Occupational Classification codes, and releases updated data annually each May. USCIS adjudicators have long accepted OEWS printouts as benchmark evidence, and published administrative appeals decisions confirm its use as the default occupational wage comparator for O-1A high salary submissions.
The OEWS data reports wage distributions at four levels and provides summary percentiles including the 10th, 25th, 50th, 75th, and 90th. For O-1A purposes, the relevant comparison is not the median but the upper tail of the distribution. The 90th percentile is the threshold most consistently treated by AAO decisions as the baseline for a persuasive high salary argument. A petitioner earning at or above the 90th percentile for the applicable SOC code is well-positioned to satisfy the criterion on salary alone. A petitioner in the 75th-to-90th percentile range can still advance a credible argument, but the case requires supplemental evidence—typically an expert letter addressing structural compensation constraints in the relevant sector—to reach the standard.
OEWS data is available at the national level and broken down by metropolitan statistical area. This geographic distinction has material consequences for O-1A analysis. A software developer earning $220,000 annually may appear at or above the 85th percentile nationally but at a lower percentile when compared against peers in a high-cost metro such as the San Francisco-Oakland-Hayward MSA. USCIS adjudicators are familiar with the tactic of selecting the most favorable geographic scope, and adjudicators may issue an RFE noting that the peer comparison should reflect the actual labor market where the petitioner works. The more defensible approach presents both national and MSA-level figures and addresses the relationship between them in the petition brief.
What the regulation requires
The regulatory text at 8 C.F.R. § 214.2(o)(3)(iii)(B)(8) identifies two distinct evidentiary paths. The first requires a salary that is high in relation to others in the field. The phrase 'in relation to others in the field' has been interpreted by USCIS and the AAO to mean the U.S. peer population in the same occupation—not the petitioner's home country, not a global average, and not a restricted subset of workers at senior levels. The criterion asks whether the petitioner's compensation is high compared to other practitioners of the same occupation measured across the U.S. workforce broadly, and the OEWS program is the primary reference source for that comparison.
The second path covers 'other significantly high remuneration for services,' which addresses compensation structures not fully captured by base salary. This prong is relevant for equity-compensated employees, commissioned professionals, grant-funded researchers, and others whose full economic value is not reflected in their W-2 alone. The AAO has accepted evidence of documented bonuses with payout history, deferred compensation arrangements, and equity grants with established market values under this prong. The petitioner must demonstrate not just that additional compensation components exist but that their aggregate value places the petitioner in a significantly high bracket compared to peers. Vague assertions about equity potential or unexercised options without documented market value carry minimal evidentiary weight under this prong.
Neither path requires the petitioner to satisfy both simultaneously. A petitioner with a base salary at the 90th percentile of the applicable OEWS distribution can satisfy the criterion on that basis alone without characterizing bonus or equity components separately. A petitioner with a base salary in the 70th percentile may satisfy the criterion if a documented bonus or equity grant brings total annual compensation above the 90th percentile threshold when aggregated. In either case, the regulation requires evidence of actual salary or remuneration, not a projection or offer. Compensation figures that cannot be verified by contemporaneous payroll records, a W-2 form, or a signed employer letter carry substantially reduced evidentiary value before USCIS.
Evidence that routinely satisfies the criterion
The strongest OEWS-based high salary exhibit combines four components. First, a printout from the most recent May BLS OEWS release showing the wage distribution for the correct SOC code and the relevant geographic scope, with the petitioner's annual salary position marked relative to the 90th percentile. Second, a payroll statement, earnings summary, or W-2 reflecting the exact annual figure used in the comparison. Third, an employer letter on institutional letterhead confirming position title, annual compensation, and full-time employment status. Fourth, an expert letter from a practitioner with direct knowledge of compensation in the relevant field who confirms that the petitioner's earnings are exceptional within the occupation. These four elements address the salary question from multiple evidentiary directions and reduce the common grounds for an RFE on this criterion.
SOC code selection is the most technically demanding aspect of the OEWS exhibit. OEWS covers approximately 830 distinct occupations, and selecting the code that most accurately reflects the petitioner's actual work is critical—not the code that produces the most favorable percentile position. A petition that uses the 'Computer and Information Research Scientists' code (15-1221) for a machine learning engineer whose compensation is being benchmarked against software developer wages (15-1252) invites scrutiny from USCIS adjudicators who compare the SOC occupational description against the job duties described elsewhere in the petition. The selected SOC code should align with the position title in the I-129, the duties described in the employer letter, and the standard occupational definitions published by BLS.
For occupations where OEWS data is less granular or where the petitioner's role spans multiple codes, supplemental wage surveys from professional associations or federal research programs can support the comparison. The NSF NCSES Survey of Doctorate Recipients reports earnings for doctoral scientists and engineers and is appropriate for academic or research-track scientists. The American Association of University Professors annual compensation survey covers faculty salaries by rank and institutional category. The Association of American Medical Colleges publishes data on clinical faculty and medical specialist compensation. These sources are most useful when the OEWS occupation code fitting the petitioner's role does not produce data granular enough to support a confident 90th percentile claim, and they are accepted by USCIS as supplemental comparators.
Evidence USCIS regularly discounts
USCIS adjudicators regularly discount salary comparisons that rely on the national median rather than the upper-end percentiles. A petition that presents an OEWS printout showing the petitioner earns above the 50th percentile for the occupation does not satisfy the high salary criterion. The criterion requires high compensation, not above-average compensation, and the median represents the midpoint of the distribution rather than a threshold of exceptionality. Similarly, an argument that the petitioner earns above the 75th percentile—meaning more than three-quarters of all workers in the occupation—will typically draw an RFE unless accompanied by evidence addressing why the 75th percentile represents a significantly high level in that particular field. AAO decisions on this criterion have consistently applied a standard closer to the top decile.
International salary comparisons are not a substitute for U.S. peer data. A petition demonstrating that the petitioner's salary exceeds the average for the same role in their country of origin does not satisfy the 'in relation to others in the field' requirement as USCIS interprets it. The regulation contemplates comparison to the U.S. workforce in the relevant occupation, and geographic scope is not a matter of discretion for petitioners currently employed in the United States. A petitioner who has recently relocated and whose prior compensation was measured in a foreign currency presents a transition-period challenge, but the solution is not an international comparison—it is a current U.S. employer letter and the most recent available U.S. payroll documentation.
Speculative or imputed compensation figures are also regularly discounted. Projected equity values based on company valuation models, estimated annual bonuses stated as a range in an employment offer rather than as a documented payout, and unsupported assertions about commission income do not satisfy the criterion. The OEWS comparison must be made against compensation that has actually been earned and paid, not potential future earnings. A petition comparing OEWS 90th percentile figures against the compensation offered in an employment letter—rather than against compensation actually received—will face scrutiny absent an employer declaration confirming that the stated rate has been paid in full and is not merely a prospective commitment.
Presenting borderline compensation situations
When the petitioner's base salary falls between the 75th and 90th percentiles of the applicable OEWS distribution, the recommended approach uses a two-track presentation. The first track presents the salary comparison explicitly, naming the exact percentile position and presenting the petitioner's earnings against the full distribution table. The second track introduces an expert letter from a practitioner with knowledge of compensation structures in the relevant industry, explaining why structural constraints specific to the employer type—NIH salary caps for federally funded researchers, university pay bands for tenured faculty, or public-sector compensation schedules for government-adjacent contractors—prevent the petitioner from earning at the market rate their qualifications would otherwise command in a comparable private-sector role. The expert letter does not manufacture a higher salary; it contextualizes why the stated salary is nevertheless exceptional given those constraints.
Petitioners whose compensation has increased significantly during a period of O-1A status face a specific challenge when filing extension petitions. A salary that was at the 65th percentile when the initial petition was approved may have grown to the 88th percentile by the time the extension is prepared. The comparison is made against current OEWS data at the time of filing, not against the release that was current when the initial petition was adjudicated. For extension petitions, the employer letter must specify the current compensation, and the OEWS exhibit must use the most recent May release. Using data from two or three years prior signals an exhibit that was not freshly assembled for the current filing and may prompt a request for updated documentation.
Joint appointments and compensation split across two institutional positions present a further complexity. A researcher holding a joint appointment at a university and a national laboratory, receiving salary from both institutions, may aggregate both figures for the high salary comparison if the total reflects compensation for a single integrated professional role. The employer letter—or letters from both institutions—must confirm the total compensation from all sources and identify each paying entity. USCIS is not obligated to aggregate compensation across separate employment relationships, so the aggregation argument must be stated explicitly in the brief and supported by documentation showing that the income streams are related, contemporaneous, and together represent the petitioner's full compensation for their primary professional work.
Building and auditing the exhibit file
A complete high salary exhibit organized for efficient adjudicator review uses a tabbed structure. Tab one is the employer letter on institutional letterhead confirming position title, annual compensation, and employment status. Tab two is the payroll record or most recent W-2 reflecting the actual earnings figure. Tab three is the BLS OEWS national printout for the selected SOC code, with the petitioner's salary marked in relation to the 90th percentile. Tab four, where relevant, is the BLS OEWS MSA-level printout for the metropolitan area where the petitioner works, with a brief explanation of the geographic scope selection. Tab five is the supplemental professional association or government survey if OEWS data alone is insufficient. Tab six is the expert letter addressing compensation norms and, where applicable, structural constraints on earnings.
Before filing, conduct a three-point audit of the exhibit. First, confirm that the salary figure in the employer letter, the payroll record, and the OEWS comparison reflects the same number—any discrepancy between these documents will prompt an RFE seeking clarification. Second, confirm that the SOC code used in the exhibit matches the occupational description in the I-129 and the job duties described in the employer letter. A mismatch between the selected SOC code and the petitioner's actual duties is among the most common technical defects in high salary exhibits and is routinely flagged by USCIS adjudicators. Third, confirm that the OEWS release used is the most recent May release—using data from two or more years prior signals an exhibit that was not freshly assembled for this filing.
The expert letter for the high salary criterion serves a different function than expert letters for the original contributions or critical role criteria. For high salary, the expert's role is to confirm the labor market context: to explain why the petitioner's specific compensation level is exceptional within the field and, if the salary falls below the 90th percentile, to address the structural constraints that limit full market-rate compensation. The letter's signatory should hold a position that gives them direct, contemporary knowledge of compensation in the relevant sector—a department chair who reviews faculty salary offers, a compensation committee member at a comparable organization, or an industry recruiter with documented exposure to compensation data. A letter describing the petitioner's qualifications without addressing field compensation norms adds limited value to this criterion.

What we see go wrong, again and again
- 01Treating extraordinary ability as a credentials checklist rather than a story of field-wide impact.
- 02Submitting bibliometric data (h-index, citation counts) without explaining what makes those numbers high relative to peers in the same sub-field.
- 03Relying on letters from collaborators or co-authors rather than independent experts who can speak to influence.
