EB-1 Priority Worker · EB-1A vs EB-1B
EB-1A or EB-1B: Two Paths Within the Same Category
EB-1A and EB-1B both sit under the "priority workers" umbrella of the first employment-based preference category. They share advantages — no PERM labor certification, premium processing availability, and historically faster movement than other EB categories. But they serve very different applicants, use different evidentiary frameworks, and have meaningfully different strategic implications.
This guide compares the two paths in detail, walks through the regulatory criteria each requires, and addresses the strategic question many applicants face: can you (or should you) pursue both at once?
What EB-1A is
EB-1A — Extraordinary Ability is for individuals who have risen to the very top of their field in the sciences, arts, education, business, or athletics. The standard, set by INA §203(b)(1)(A), is "sustained national or international acclaim" and demonstrated recognition that the achievements have been recognized in the field.
Eligibility is shown one of two ways:
- A one-time major internationally recognized award (Nobel Prize, Academy Award, Olympic gold, Pulitzer, etc.); or
- Meeting at least 3 of 10 regulatory criteria listed at 8 CFR §204.5(h)(3), combined with a "final merits determination" that the applicant is among a small percentage at the top of the field.
The key features
- No job offer required. Applicants self-petition by filing the I-140 directly.
- No PERM labor certification. Skips the months (often more than a year) of the labor certification process.
- Any field qualifies. Not limited to academic or research roles.
- Premium processing available. USCIS adjudicates the I-140 within 15 business days for an additional fee.
- Work flexibility after green card. No requirement to remain with any particular employer.
The trade-off: EB-1A has a high evidentiary bar. The applicant must demonstrate sustained acclaim — not just substantial accomplishment.
What EB-1B is
EB-1B — Outstanding Professor or Researcher is for individuals internationally recognized as outstanding in a specific academic field. The standard is "international recognition," and the applicant must have at least three years of teaching or research experience in the field.
The position the applicant takes in the U.S. must be one of the following:
- A tenured or tenure-track teaching position at a U.S. university or institution of higher education;
- A comparable research position at a U.S. university or institution; or
- A research position with a private employer that has at least three full-time researchers and documented accomplishments in the academic field.
The key features
- Job offer required. A permanent or long-term research or teaching position must be offered by a qualifying U.S. institution.
- Employer files the petition. Unlike EB-1A, this is not a self-petition. The sponsoring institution files the I-140.
- No PERM labor certification. Same as EB-1A.
- Premium processing available. USCIS extended premium processing to EB-1B and now adjudicates these I-140s within 15 business days for the premium fee.
- Three-year experience minimum. Counted in teaching or research roles.
The trade-off: EB-1B comes with employer sponsorship and the dependencies that creates. If the offered position changes substantially, the petition may need to be refiled.
Side-by-side comparison
| Aspect | EB-1A | EB-1B |
|---|---|---|
| Fields eligible | Sciences, arts, education, business, athletics | Academic and research only |
| Self-petition allowed | Yes | No — employer files |
| Job offer required | No | Yes — tenure-track or qualifying research role |
| Experience minimum | None specified | 3 years in teaching or research |
| Evidentiary criteria | 3 of 10 regulatory criteria + final merits determination | 2 of 6 regulatory criteria + international recognition |
| PERM labor certification | Not required | Not required |
| Premium processing | Available — 15 business days | Available — 15 business days |
| Post-approval flexibility | No employer dependence | Position-dependent; changes may require refiling |
| I-140 fee | Standard I-140 fee | Standard I-140 fee + employer's burden to file |
The 10 EB-1A criteria
Under 8 CFR §204.5(h)(3), an EB-1A applicant without a one-time major award must satisfy at least three of the following ten criteria:
EB-1A regulatory criteria (must meet at least 3)
- Receipt of lesser nationally or internationally recognized prizes or awards for excellence in the field.
- Membership in associations that require outstanding achievement as judged by recognized national or international experts.
- Published material about the applicant in professional publications or major media, relating to the applicant's work in the field.
- Participation as a judge of others' work in the field (peer review, conference review, grant panels).
- Original contributions of major significance to the field.
- Authorship of scholarly articles in professional or major trade publications.
- Display of work at artistic exhibitions or showcases (most applicable to artistic fields).
- Performance in a leading or critical role at organizations with distinguished reputations.
- Command of a high salary or significantly higher remuneration compared to others in the field.
- Commercial successes in the performing arts, as shown by box office receipts or sales.
Meeting the count of criteria is only the first step. The strength of evidence under each criterion — and how the evidence collectively shows sustained acclaim — drives outcomes.
The Kazarian two-step framework
USCIS adjudicates EB-1A petitions under a two-step framework established by the Ninth Circuit's 2010 decision in Kazarian v. USCIS and adopted by USCIS in subsequent policy guidance.
Meeting three criteria gets you to step two. Step two is where the petition is actually won or lost.
Step 1 — Counting the criteria
USCIS first looks at whether the petitioner has submitted evidence satisfying at least three of the ten regulatory criteria. This is a relatively straightforward inventory question: do you have qualifying evidence under at least three of the ten boxes?
Step 2 — The final merits determination
If the answer to step one is yes, USCIS proceeds to a holistic "final merits determination": does the totality of the evidence, including the criteria satisfied, demonstrate that the applicant has risen to the very top of the field and enjoys sustained national or international acclaim?
This is where strong-looking petitions on paper can still receive denials or RFEs. Satisfying three criteria with relatively weak evidence under each is different from satisfying five criteria with strong evidence under each. The final merits determination is qualitative.
USCIS has been issuing more EB-1A RFEs focused on the final merits determination — particularly questioning whether the applicant's accomplishments are at the level of "the very top of the field" rather than merely substantial. For RFE response strategy adapted to current practice, see our EB-1A RFE response article (forthcoming).
The 6 EB-1B criteria
Under 8 CFR §204.5(i)(3)(i), an EB-1B applicant must satisfy at least two of six criteria, along with the three-years-of-experience requirement and the qualifying job offer:
EB-1B regulatory criteria (must meet at least 2)
- Receipt of major prizes or awards for outstanding achievement in the academic field.
- Membership in associations that require outstanding achievements of their members.
- Published material in professional publications written by others about the applicant's work in the academic field.
- Participation as a judge of others' work in the same or allied academic field.
- Original scientific or scholarly research contributions in the field.
- Authorship of scholarly books or articles in scholarly journals with international circulation in the field.
EB-1B applies an "international recognition" standard — less stringent than EB-1A's "sustained national or international acclaim" but still demanding. The institutional context (the employer's reputation, the position offered) also matters in the evaluation.
Which to choose
Choose EB-1A if...
You want independence and broad flexibility
- You have national or international recognition (awards, patents, publications with substantial citations, media coverage, significant industry recognition)
- You want to maintain freedom to change roles or work independently
- You don't have a qualifying academic job offer — or you're not in academia
- You're an entrepreneur, founder, or independent professional
- You want the option to file without involving your current employer
Choose EB-1B if...
You're a recognized academic with a permanent offer
- You're an academic researcher or professor with at least 3 years of post-degree experience
- You have a tenure-track or comparable permanent research offer in hand
- The sponsoring institution is willing to file the petition
- Your strongest evidence is in publications, citations, peer review, and academic contributions
- You're comfortable with the institutional dependence (your green card is tied to the role)
For applicants whose profiles could support either category — established academics with significant independent recognition — the choice is often strategic rather than necessary. EB-1B's standard is somewhat more attainable for many academics; EB-1A offers more flexibility after approval.
Can you pursue both?
Yes. Multiple I-140 petitions in different categories are permitted, and pursuing EB-1B through the employer while self-petitioning for EB-1A is a recognized strategy. Each petition must stand on its own evidentiary record.
When parallel filing makes sense
- The academic profile is borderline EB-1A. The petitioner has substantial accomplishments but the EB-1A "very top of the field" determination may be challenging. EB-1B as a backup provides protection if the EB-1A is denied.
- The petitioner wants flexibility after approval. EB-1A green card holders aren't tied to the sponsoring institution. EB-1B holders may face complications if they leave the role too quickly.
- The sponsoring institution is supportive. EB-1B requires the institution to file the petition. If the institution is willing, the parallel EB-1A self-petition adds no burden to them.
- Different priority dates matter. If both petitions are approved, the earlier priority date carries over under 8 CFR §204.5(e).
The narrative consistency concern
Parallel filings should present consistent narratives. If the EB-1B emphasizes the applicant's commitment to a specific academic position and the EB-1A emphasizes flexibility and independent recognition, USCIS officers can pick up on the tension. The strongest parallel approach uses overlapping evidence that supports both standards without contradicting either.
The 2026 context
EB-1 retrogression for India and China
The June 2026 Visa Bulletin shows EB-1 India retrogressed to December 15, 2022 and EB-1 China at April 1, 2023. For worldwide applicants, EB-1 remains Current or close to Current. This affects both EB-1A and EB-1B equally — they share the EB-1 priority date queue.
The retrogression has not changed the eligibility standards, but it has changed the strategic timing calculation. Pursuing EB-1 still offers speed advantages over EB-2 for India and China, but the dramatic "EB-1 is current, EB-2 is years out" gap that existed in earlier years is narrower.
The May 2026 AOS memo
USCIS issued PM-602-0199 on May 21, 2026, signaling heightened discretionary scrutiny at the adjustment-of-status stage. EB-1A and EB-1B applicants are generally well-positioned under the memo — extraordinary ability and international recognition are factors that work in the applicant's favor at the discretionary level. For deeper coverage, see our PM-602-0199 article.
Premium processing is now standard practice
Both EB-1A and EB-1B I-140s are eligible for premium processing — 15 business days for an additional fee. Many practitioners now use premium processing routinely for these petitions to obtain prompt I-140 approvals supporting AC21 §104(c) H-1B extensions and other downstream benefits.
Common questions
What's the main difference between EB-1A and EB-1B?
EB-1A is for extraordinary ability in any field, self-petition allowed, no job offer required. EB-1B is for outstanding professors and researchers, requires a qualifying U.S. job offer, and must be filed by the sponsoring institution. The two share the same priority date queue and both skip PERM.
Is EB-1A harder to qualify for than EB-1B?
For academic researchers, generally yes. EB-1A's "sustained national or international acclaim" standard, combined with the Kazarian final merits determination, is more demanding than EB-1B's "international recognition" standard. Many academics who would have moderate-to-strong EB-1B cases face higher scrutiny under EB-1A. The trade-off is flexibility: EB-1A doesn't tie the applicant to a sponsoring institution.
Can I apply for both at the same time?
Yes. Multiple I-140 petitions are allowed, and pursuing EB-1B through the employer while self-petitioning for EB-1A is a recognized strategy. Each petition must stand on its own evidentiary record, and the narratives across the two filings should be consistent.
Is a PhD required for EB-1A or EB-1B?
No. EB-1A has no education requirement at all — what matters is evidence of sustained acclaim, regardless of credentials. EB-1B requires three years of teaching or research experience but does not formally require a PhD; however, most EB-1B applicants have PhDs because the academic positions that qualify typically require one.
What evidence is needed for EB-1A?
The petitioner needs to satisfy at least three of ten regulatory criteria — awards, association memberships, published material about the applicant, judging others' work, original contributions of major significance, scholarly publications, display at artistic exhibitions, critical role at distinguished organizations, high salary, or commercial success in the performing arts. Beyond the count, the strength of evidence under each criterion and the final merits determination drive outcomes. Strong recommendation letters from independent experts add substantial weight.
Is premium processing available for EB-1B?
Yes. USCIS extended premium processing to EB-1B I-140s, with 15-business-day adjudication for an additional fee. Premium processing is now standard practice for many EB-1A and EB-1B filings, particularly when applicants need prompt I-140 approval to support AC21 §104(c) H-1B extensions or other downstream benefits.
Evaluating EB-1A or EB-1B for your profile?
The right path depends on your specific evidence, your career stage, your country of birth, and your strategic goals — including whether you want institutional flexibility after approval. A free evaluation walks through your profile honestly and identifies which EB-1 path (or combination) makes sense. No obligation.
