How many EB1A criteria does a petitioner need to satisfy?

A petitioner must satisfy at least 3 of the 10 criteria under 8 CFR 204.5(h)(3), then pass the Kazarian step-2 final merits determination showing sustained national or international acclaim.

What is the Kazarian two-step framework?

[Kazarian v. USCIS, 596 F.3d 1115](https://law.justia.com/cases/federal/appellate-courts/ca9/08-56094/08-56094-2010-03-04.html) requires USCIS to (1) determine whether submitted evidence meets each criterion on its own terms, then (2) conduct a final merits determination on the totality of evidence. USCIS cannot conflate the two steps.

Can a software engineer qualify for EB1A without academic publications?

Yes. Engineers can satisfy Criterion 5 (original contributions) with non-publication evidence: GitHub adoption metrics, open-source community uptake, expert letters from practitioners, and named organizational adoption of tools or frameworks.

What is the difference between EB1A and O-1A?

Both use the same 8 criteria framework but EB1A is a permanent residence category (green card) while O-1A is a nonimmigrant visa. EB1A adjudication is generally stricter; O-1A can serve as a strategic stepping stone while building an EB1A-qualifying record.

How long does EB1A petition preparation take?

Manual EB1A petition preparation typically takes 100–200 hours across document review, criteria mapping, drafting, expert letter coordination, and quality review. With AI-assisted tools, attorneys report 20–40 hours total for a well-documented client. The bottleneck is almost always expert letter coordination.

What is the most commonly challenged EB1A criterion?

Criterion 5 (original contributions of major significance) is the most frequently challenged in RFEs and denials. USCIS requires evidence that the contribution had major significance to the field broadly — not just to the petitioner's employer — and increasingly scrutinizes generic download metrics or citation counts without named organizational adoption or independent expert support.

When should an attorney consider O-1A before EB1A?

O-1A is the right approach when the client cannot yet satisfy 3 EB1A criteria at the required evidentiary standard. O-1A uses the same criteria framework but is adjudicated at a lower threshold and does not require a Kazarian step-2 final merits analysis. A successful O-1A approval demonstrates that USCIS found the criteria evidence sufficient, which can be leveraged in subsequent EB1A preparation.

How do expert letters factor into EB1A adjudication?

Expert letters are essential for Criterion 5 (original contributions) and are strongly recommended for Criterion 8 (critical role). Letters from independent experts — researchers or practitioners with no affiliation to the petitioner's employer — carry more weight than employer letters. USCIS applies heightened scrutiny to letters that recite regulatory language without providing specific evidence of the contribution's significance.

EB1A Mastery

EB1A & O-1 Domain Mastery: Attorney Resource Hub

The definitive resource hub for immigration attorneys on EB1A and O-1 visa petitions. Covers criteria guides, case strategy, RFE prevention, and AAO decisions.

April 19, 2026·Updated May 6, 2026·8 min read

EB1A and O-1 extraordinary ability petitions are among the most evidence-intensive immigration cases an attorney handles. A successful petition requires strategic criteria selection, well-documented evidence for each criterion, expert letters from independent sources, and a coherent step-2 argument tying the evidence into a unified extraordinary ability narrative. This hub organizes every resource an attorney needs to prepare winning petitions — from criteria analysis and evidence strategy to petition drafting, RFE prevention, and AAO decision analysis.

10 criteria

EB1A qualifying criteria under 8 CFR 204.5(h)(3) — 3 must be satisfied

The 10 criteria range from nationally recognized awards (Criterion 1) to high salary (Criterion 9). Criterion 5 (original contributions) and Criterion 8 (critical role) are the workhorses for professional petitions, but which three criteria to argue is a case-specific strategic decision that requires evidence assessment before commitment.

2-step

The Kazarian analysis that governs every EB1A adjudication

Kazarian v. USCIS (9th Cir. 2010) established that USCIS must first evaluate each criterion on its own terms, then conduct a separate final merits determination on the totality of evidence. Step 2 is where most denials happen — not because criteria evidence is missing, but because the petition doesn't make the extraordinary ability argument explicitly.

40–60%

Approximate EB1A initial filing approval rate — the bar is high but regularly cleared

RFEs issue on roughly 40–60% of cases; most RFE responses succeed. The approval rate for well-prepared petitions with strong Step 2 arguments and properly documented evidence is significantly higher than for poorly structured filings. Attorney strategy and petition quality matter more than raw credential count.

AAO non-precedent decisions reveal which criteria arguments succeed and fail in current adjudication. The evidence patterns the AAO approved in 2024–2025 are the clearest signal of what USCIS will accept. See AAO EB1A Decisions 2024–2025 before committing to a criteria strategy.

RFE Prevention and Response

RFEs issue on roughly half of all EB1A initial filings. Prevention is more efficient than response — but when an RFE arrives, the response determines the outcome.

The EB1A RFE Prevention Playbook: 8 Patterns The 8 most common EB1A RFE trigger patterns from 2023–2025 AAO decisions, with prevention strategies for each. Criterion 5 major significance, Criterion 8 organizational distinction, and generic expert letters are the most frequent triggers.

The most common RFE pattern is generic Criterion 5 evidence without named adoption

USCIS has been increasingly consistent: download counts, citation counts, and GitHub stars alone are insufficient for Criterion 5 major significance. Named organizational adoption — specific third parties who built on or implemented the contribution — is the evidence that prevents the RFE or wins the response. Build this evidence before filing.

Expert Letters

Expert letters are required for Criterion 5 and recommended for Criterion 8. Their quality determines whether the criteria evidence is persuasive.

O-1A and EB1A use the same criteria — the differences are in the standard and the pathway

O-1A uses criteria parallel to EB1A but is adjudicated without a Kazarian step-2 final merits requirement. This makes O-1A more accessible for clients who satisfy criteria but cannot yet make the sustained national acclaim argument. An O-1A period gives the client time to build a stronger EB1A record — additional citations, publications, expert letter sources — before filing the green card petition.
