How to Obtain and Present Employer Salary Comparison Letters for the O-1A High Salary Criterion
The high salary criterion is accessible for many O-1A petitioners, but poorly framed salary exhibits are a common source of RFEs. This guide explains how to obtain and structure employer salary comparison letters that give USCIS the context needed to credit the criterion.
The high salary criterion in context
The O-1A high salary criterion, codified at 8 C.F.R. § 214.2(o)(3)(iii)(A)(6), requires the petitioner to command a salary or other remuneration that is high relative to others in the field. For many O-1A petitioners — particularly those in industry roles rather than traditional academic appointments — the salary criterion is among the most accessible criteria available, because direct compensation evidence is relatively easy to document and compare. At the same time, USCIS adjudicators have become more skeptical of poorly framed salary exhibits, dismissing comparisons that rely on overly broad occupational categories or geographic averages that do not reflect the petitioner's specific field and seniority level.
The most commonly used salary benchmarks come from Bureau of Labor Statistics Occupational Employment and Wage Statistics data, published annually with occupational codes organized by Standard Occupational Classification numbers. BLS OEWS data provides percentile wage tables at national, state, and metropolitan area levels, allowing a petitioner to compare their compensation against the 90th, 75th, and median percentiles for their specific occupation. However, BLS OEWS data operates at the occupational level rather than the field-of-extraordinary-ability level, and a petitioner who commands a salary at the 90th percentile for their SOC code may still face an RFE if USCIS finds the SOC code too broad to be meaningful.
Employer salary comparison letters — written by a human resources representative or senior executive at the petitioning organization — address the gap between population-level wage data and the petitioner's specific position. They provide direct, authoritative knowledge of how the petitioner's compensation compares to similarly situated colleagues within the same organization and the same field. When properly drafted, employer letters confirm that the petitioner's salary falls in the top tier of their peer group at the organization, supplement external wage data with organizational context, and explain non-salary components that increase the total compensation comparison.
What the regulation requires
Section 8 C.F.R. § 214.2(o)(3)(iii)(A)(6) provides that the petitioner may establish extraordinary ability by demonstrating a high salary or remuneration relative to others in the field. The USCIS Policy Manual, Part O, Chapter 6, interprets this criterion to require a meaningful comparison — not just proof that the petitioner earns a particular dollar amount, but evidence establishing the relative standing of that compensation against peers at a comparable experience level within the petitioner's specific field or subfield. USCIS has consistently held that a comparison group must be appropriately defined: too broad a comparison understates the petitioner's relative standing when the petitioner works in a specialized high-compensation subfield.
The regulation uses the phrase 'salary or other remuneration' intentionally. Total compensation packages for senior industry professionals routinely include equity compensation in the form of stock options or restricted stock units, performance bonuses that may exceed base salary, deferred compensation arrangements, and significant non-salary benefits including research budgets or equipment stipends. USCIS accepts total compensation comparisons when the components are clearly documented and the comparison is made on a like-for-like basis. A petition relying on total compensation must present both the components and the source showing how each component is treated in the relevant comparison group.
The employer salary comparison letter serves a distinct function from publicly available wage data: it provides first-hand, authoritative confirmation of where the petitioner's specific compensation falls relative to their actual peer group. USCIS adjudicators who find that public wage data places the petitioner near but not clearly above the 90th percentile may be persuaded by an employer letter confirming that within the organization and specific field, the petitioner is among the highest-paid professionals. USCIS has credited such letters in approved decisions when they are specific, signed by someone with direct knowledge of compensation decisions, and consistent with public wage data already in the record.
Employer salary comparison letters that work
Effective employer salary comparison letters share several structural characteristics. They identify the letter writer by title and explain why that person has knowledge of compensation decisions at the organization — typically a vice president of human resources, a director of compensation, or a senior executive with oversight of the petitioner's department. They state the petitioner's current total compensation broken down by component, and compare it to a clearly defined peer group: other professionals at the same seniority level in the same functional area within the organization. The letter should state specifically where in the distribution the petitioner falls — whether their compensation is in the top ten percent, top five percent, or comparable measurable fraction of the defined peer group.
The comparison group must be specific enough to be meaningful. A letter stating that the petitioner's salary is above average for all employees at the company adds little value when the organization employs thousands across many functions. The comparison should be limited to professionals in the same field and at a comparable seniority level — for example, principal engineers in a machine learning infrastructure division. If the organization is small and the peer group is narrow, that context should be provided explicitly: a letter confirming that the petitioner is the highest-compensated professional in a team of twelve is credible and specific, even though the absolute group size is small.
Letters should also address any structural features of the compensation that could otherwise appear confusing in isolation. If the petitioner accepted below-market base salary in exchange for a substantial equity grant, the letter should explain this arrangement and provide context for how equity grants at that level compare to market practice. If the petitioner is compensated partly through research budget allocations or equipment that other employers would pay directly, the letter should explain the economic equivalent. The goal is to give the USCIS adjudicator a complete picture of economic standing — one that supports the inference that the petitioner's compensation reflects an employer's judgment that they are among the most valuable professionals in the field.
Evidence USCIS discounts
The most common reason salary comparison evidence fails is that the comparison group is too broad. An employer letter confirming that a petitioner earns above the industry average without specifying the industry, the occupation, the seniority level, or the geography provides no useful comparative benchmark. Similarly, letters that compare the petitioner's total compensation to base-salary data from a published survey, or that compare domestic compensation to foreign wage tables, introduce methodological inconsistencies that USCIS will identify in an RFE. The standard requires a meaningful, apples-to-apples comparison — same occupation, same seniority, same or comparable geographic market — and any deviation requires explicit explanation.
BLS OEWS wage tables are well-established evidence, but they have known limitations for high-compensation petitioners in specialized fields. The BLS SOC system organizes occupations at a level of specificity that may not distinguish between the petitioner's specialized role and a broader category that includes lower-paid workers. A petitioner who works as a principal research scientist in a competitive applied machine learning context might fall within the 'Computer and Information Research Scientists' SOC code, which aggregates compensation across academic and industry roles at all experience levels. An employer letter or private compensation survey targeted to the specific role and level is necessary to fill the gap that BLS data leaves.
Letters that rely on the letterhead of a well-known organization without providing a specific comparative analysis are also routinely discounted. USCIS adjudicators have seen letters from major technology companies stating the petitioner's compensation without placing it in context of a peer group. These letters confirm the amount but do not establish the relative standing that the criterion requires. An employer letter stating only that the petitioner earns a certain amount per year and the employer considers this competitive does not demonstrate that the amount is high relative to others in the field — it demonstrates only that the employer finds the amount acceptable, which falls short of the regulatory standard.
Presenting borderline salary evidence
When the petitioner's base salary does not clearly exceed the 90th percentile on its own, total compensation is the natural expansion. Equity compensation requires careful documentation: stock option grants should be supported by the grant notice, the vesting schedule, and a current or at-grant fair market value per share; restricted stock units should be supported by the grant agreement and vesting schedule; and any methodology for computing annualized equity value should be consistent with how the comparison survey or employer letter treats equity. If the private compensation survey the petition relies on measures total cash compensation rather than total compensation including equity, the equity component cannot simply be added on top without adjusting the comparison baseline.
Geographic adjustment is an important framing tool for petitioners whose compensation appears average nationally but is elevated in the relevant labor market. A petitioner working in a major metropolitan area with high competition for talent may earn a salary that appears near the national 90th percentile while actually falling below the median for their specific metro area and field. In that situation, the petition should use BLS OEWS metropolitan area data, supplemented by private salary survey data from surveys that publish metro-level results, to establish that the petitioner's compensation is high relative to professionals doing comparable work in the same market.
When the salary evidence is genuinely borderline, the petitioner's overall petition posture matters. A petition with strong evidence across multiple other criteria — peer review records, original contributions, awards, and expert recognition — can absorb a salary criterion that is persuasive rather than compelling. The petition brief should frame the salary evidence accurately, acknowledge the comparison context, and direct USCIS attention to the totality of evidence. An inflated or implausible salary comparison that USCIS corrects in an RFE undermines credibility for the entire petition; an honest presentation of strong but not overwhelming salary evidence is always the better approach.
Building and assembling the salary exhibit
The salary exhibit should be organized as a self-contained section of the petition package, typically labeled as an exhibit tab following the petition brief's discussion of the high salary criterion. The exhibit should begin with the employer letter, which introduces the petitioner's total compensation in context. It should then include the supporting documentation: the employment agreement or offer letter reflecting base salary, bonus target, and equity grant; the most recent equity grant documentation; and any supplemental compensation such as research budget allocations. Each item should be labeled clearly and cross-referenced to the petition brief's salary criterion discussion so the adjudicator can follow the argument without searching through the package.
The BLS OEWS wage table extract should be reproduced with the relevant SOC code identified, the geographic level specified, and the relevant percentile rows highlighted. If the petitioner's field requires a SOC code selection that involves judgment — for example, choosing between 'Software Developers' and 'Computer and Information Research Scientists' — the petition brief should explain the selection and why the chosen code best reflects the petitioner's actual work. If multiple SOC codes plausibly apply, the petition can present comparisons under the most favorable defensible code while acknowledging the range, provided the argument is transparent and the best-fit code is supported by a description of the petitioner's actual job duties.
Private compensation surveys — published by industry associations, professional societies, or compensation advisory firms — can supplement BLS OEWS data when they provide more granular occupational definitions, more current data, or better coverage of the petitioner's specific industry segment. Surveys commonly cited for O-1A petitions include the Radford Global Technology Survey for technology roles and published salary surveys from professional associations such as the American Chemical Society, the Association for Computing Machinery, and the Society for Human Resource Management. When using private surveys, the petition should identify the survey, the survey date, the occupational category used, and the percentile data extracted — and the employer letter should confirm that the petitioner's compensation falls in the cited range.
What we typically gather for this kind of case
| Document | Where to source | Why it matters |
|---|---|---|
| Peer-reviewed publications | Web of Science / Scopus exports | Anchors original-contributions and authorship criteria |
| Citation analysis | Google Scholar profile + ESI top-1% data | Quantifies major significance in the field |
| Salary benchmark | BLS OEWS for SOC code + locality | Documents high-salary criterion at 90th-percentile or above |
| Critical-role letters | Direct supervisor + program director | Establishes role's importance, not just title |
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.
