H-1B Expert Opinion Letters — specialty occupation and RFE response.
ProfVal's H-1B Expert Opinion Letters may help address USCIS specialty occupation requirements for the position, the beneficiary's qualifications, or both. Used for initial filings and RFE responses — written by U.S.-based distinguished experts and informed by continuous study of H-1B RFEs and denials since 2019.
Most clients work with us by email — but for complex cases, we can also facilitate direct engagement between our team, experts, and employers to develop first-hand knowledge of the position.
KEY DEFINITIONS
What is an H-1B RFE?
A Request for Evidence (RFE) is a formal notice from USCIS indicating that additional documentation may be needed to approve an H-1B petition. Receiving an RFE does not mean the petition is denied — it means USCIS needs more information before making a decision.
The most common H-1B RFE concerns specialty occupation — whether the position genuinely requires a bachelor's degree or higher in a specific specialty, and whether the beneficiary's credentials meet that standard. An Expert Opinion Letter may help address these concerns.

#1 reason for an H-1B RFE
What is a specialty occupation?
A specialty occupation requires theoretical and practical application of a body of highly specialized knowledge, and attainment of a bachelor's degree or higher in the specific specialty as a minimum for entry. This body of knowledge need not derive from a single degree field — USCIS recognizes that some positions may require a convergence of knowledge across multiple disciplines.
ProfVal's experts can address both straightforward and complex specialty occupation arguments — including positions where multiple degree fields together may constitute the required body of knowledge
TOP 5 RFE CONCERNS
Why H-1B RFEs are issued.
H-1B RFEs have tended to fall into five primary categories. ProfVal's letters may help address the three most common. The remaining two are legal matters your attorney will need to handle.
An EOL may be helpful in supporting your legal team's work when an RFE or NOID focuses on:
An EOL is unlikely to be valuable in supporting your legal team's work for RFEs or NOIDs focused on:
1
Specialty occupation — the position
USCIS may question whether the position genuinely requires a bachelor's degree or higher in a specific specialty.
A ProfVal EOL can provide an expert analysis of the role's duties — including complex cases where the required body of knowledge may span multiple disciplines.
2
Beneficiary qualifications
USCIS may question whether the beneficiary's academic background and experience meet the specialty occupation requirements.
A ProfVal EOL can evaluate the beneficiary's credentials in relation to the role — including work experience equivalency where applicable.
3
Wage level — a growing concern in 2026
USCIS is increasingly scrutinizing whether the offered wage correctly reflects the complexity of the position.
In 2026, more petitioners are seeing wage level questioned at the RFE stage. A Salary Assessment Letter may help address this — and may help prevent an RFE on wage grounds when included with the initial filing.
4
Employer-employee relationship — attorney-led
Typically addressed through legal documentation. Your attorney will guide you on this.
4
Maintenance of status / availability of work — attorney-led
Legal matters that ProfVal does not address. Your attorney will need to handle these concerns.
WHAT TYPE OF H-1B EXPERT OPINION LETTER DO I NEED?
H-1B EOL types — matched to your USCIS concern.
ProfVal offers different H-1B Expert Opinion Letter types depending on what USCIS has questioned. Attorneys guide which type best fits the petition strategy.
Position only
Standard specialty occupation EOL
An expert analyzes the position based on specialty occupation criteria — demonstrating that the role may require a bachelor's degree or higher in a specific specialty, including complex multi-discipline cases.
Note: if USCIS subsequently questions the beneficiary's qualifications, a second letter may be needed. Consider the combined letter to address both at once.
Position & beneficiary (Recommended)
Specialty occupation + academic credentials EOL
Combines expert analysis of the position with a detailed discussion of the beneficiary's academic credentials — aligning the role and qualifications in a single document.
Our recommended option. Doing both together is more efficient, more cohesive, and can avoid a potential second RFE on qualifications.
Academic transcript evaluation
A specialty occupation requires the equivalent of a U.S. bachelor's degree. If the beneficiary holds a foreign degree, an academic transcript evaluation may confirm U.S. equivalence.
This can be bundled into your order or purchased via a third-party (See referral options)
2026 trend
Salary Assessment Letter
A research-backed evaluation of prevailing wage and compensation standards for the position, industry, and geography.
In 2026, more H-1B petitioners are seeing wage level questioned at the RFE stage.
Including a salary assessment with the initial filing may help prevent an RFE on wage grounds entirely.
Available as a brief add-on to a specialty occupation and academic credentials EOL or as an in-depth standalone, Salary Assessment Letter.
Optional add-on
Expert employer consultation / interview
USCIS may challenge whether an expert's opinion is based on genuine first-hand knowledge of the position. To address this, ProfVal can facilitate an optional video call between a member of our team, the expert, and the employer — giving the expert direct, documented exposure to the role.
Most clients work with us by email and do not need this. It may be valuable for highly technical roles or when a prior RFE has challenged the expert's familiarity with the position.
When an expert consultation / interview may be useful
Positions with highly technical duties that are difficult to convey through documents alone
-
Cases where a prior RFE has challenged the expert's knowledge of the position
-
High-stakes RFE responses or motions to reopen where additional credibility may be important
H-1B TRENDS
H-1B denial rates and adjudication trends.
H-1B denial rates have fluctuated significantly over the past decade — driven by executive orders, USCIS policy memoranda, federal court rulings, and political priorities.
2010–15
Denial rates in the single digits — 7%, 8%, and 6% respectively. Relatively predictable adjudication environment. 1
2017–18
Rates rose sharply following the "Buy American, Hire American" executive order and USCIS policy memoranda. Peak denial rate of 24% in FY 2018.1,2
2021
Federal court decisions returned denial rates to 4% in FY 2021 and 2% in FY 2022 — the two lowest rates ever recorded. 1,2
2025–26
Political considerations following the 2024 elections are again affecting timing, fees, and adjudication decisions — leading to increased RFE activity.
ProfVal's research team has studied H-1B adjudication trends continuously since 2019 — and makes some of that research freely available.

CONTINUOUS IMPROVEMENT
We're constantly adapting H-1B EOLs based on adjudication trends
Attorneys come to us after receivingH-1B RFEs and NOIDs— and that real-world context sharpens our approach over time. Because we don't seek to profit from revisions, law firms let us know where USCIS pushes back and we work together to address it. That learning transfers not just to the individual case, but to every letter that follows.
Continuous RFE analysis
ProfVal has studied H-1B RFEs and denials continuously since 2019 — building an understanding of adjudication patterns that informs every letter we produce.
Data-driven updates
H-1B adjudication is acutely sensitive to political priorities. Our approach reflects the current environment — including renewed scrutiny of specialty occupation and wage level determinations in 2025–26.
Not available to AI tools
Our adjudication intelligence is built from real cases — not public data or training sets. It cannot be replicated by any AI tool or general knowledge base, regardless of how it is prompted.
