The choice between EB-1A and EB-1B comes down to two questions: are you a professor or researcher with a permanent U.S. job offer, and do you want to file the petition yourself or have an employer do it? EB-1A (extraordinary ability) lets you self-petition in any field if you can prove sustained national or international acclaim. EB-1B (outstanding professors and researchers) is narrower, requires three years of academic experience and a permanent job offer, and must be filed by the U.S. employer. Both fall inside the employment-based first preference, which receives 28.6 percent of all employment-based immigrant visas each year.
Who Qualifies for EB-1A
EB-1A is for people who rank among the small percentage at the very top of their field, whether that field is science, arts, education, business, or athletics. You must show sustained national or international acclaim through extensive documentation. A single major internationally recognized award, such as a Nobel Prize or an Olympic medal, satisfies the standard by itself. Without that kind of one-time achievement, you must present evidence meeting at least three of ten regulatory criteria.
Those ten criteria are:
- Nationally or internationally recognized prizes or awards for excellence.
- Membership in associations that require outstanding achievement as a condition of admission.
- Published material about you in professional or major trade publications.
- Serving as a judge of others’ work in the same or a related field.
- Original contributions of major significance to your field.
- Authorship of scholarly articles in professional journals or other major media.
- Display of your work at artistic exhibitions or showcases.
- Performing a leading or critical role in distinguished organizations.
- Salary or remuneration significantly above others in your field.
- Commercial success in the performing arts, supported by box office receipts, sales records, or similar evidence.
If the standard criteria don’t fit your occupation, you can submit comparable evidence that demonstrates an equivalent level of achievement. That flexibility matters in newer or nontraditional fields where prizes, memberships, and journal publications aren’t the standard currency of recognition.
The structural advantage of EB-1A is that you file for yourself. No employer sponsorship, no job offer. You submit Form I-140 on your own behalf, and once you get your green card you’re free to work for any employer, launch your own venture, or change jobs. There is also no minimum experience threshold. If you can prove you’re at the top of your field, it doesn’t matter whether you’ve been working three years or fifteen.
Who Qualifies for EB-1B
EB-1B covers professors and researchers who are internationally recognized for outstanding achievements in a specific academic field. You need at least three years of teaching or research experience in your specialty, and you need a qualifying job offer from a U.S. employer. The employer, not you, files the petition.
The offered job must be a tenured or tenure-track teaching position, or a comparable permanent research position. If the employer is a private company rather than a university, it must employ at least three full-time researchers and have documented accomplishments in the academic field. That requirement filters out employers who lack the infrastructure to support serious research work.
You must meet at least two of six regulatory criteria:
- Major prizes or awards for outstanding achievement in your academic field.
- Membership in associations that require outstanding achievements of their members.
- Published material by others about your academic work in professional publications.
- Participation as a judge of the work of others in the same or a related academic field.
- Original scientific or scholarly research contributions to the field.
- Authorship of scholarly books or articles in journals with international circulation.
Comparable evidence is allowed here too if the standard six don’t fit your situation.
Side-by-Side: How the Two Categories Differ
The most practical difference is sponsorship. EB-1A lets you self-petition with no employer involvement. EB-1B requires a U.S. employer to file on your behalf and offer you a permanent or tenure-track position. That single split shapes the entire process. EB-1A applicants control their own timeline. EB-1B applicants depend on their employer’s willingness and cooperation.
The math of the criteria also differs. EB-1A asks for three of ten. EB-1B asks for two of six. On paper EB-1B looks easier, but the eligible pool is far more restrictive: only professors and researchers in academic fields qualify. EB-1A reaches a much broader range of occupations, including business leaders, athletes, artists, and professionals in any field who can show sustained top-tier recognition.
Experience is another dividing line. EB-1B has a strict three-year requirement, and the experience must be in the same academic field you’ll work in. EB-1A has no minimum experience at all.
What happens if you switch jobs also differs. An EB-1A green card carries no ongoing employer tie. An EB-1B is built around a specific employer’s offer, so a change of plans partway through can disrupt the petition (though portability rules can help once the case is far enough along).
How USCIS Actually Decides Your Case
Meeting the minimum criteria doesn’t guarantee approval. Since the Kazarian v. USCIS decision, adjudication follows a two-step framework, and the second step is where many otherwise qualified applicants fall short.
Step one is a threshold check. The officer verifies that your evidence satisfies the required number of regulatory criteria: three of ten for EB-1A, two of six for EB-1B. If the evidence doesn’t clearly fit that many categories, the petition stops here.
Step two is a final merits determination. The officer evaluates all your evidence together to decide whether, taken as a whole, it actually demonstrates that you are among the small percentage at the top of your field with sustained national or international acclaim. Meeting three individually thin criteria can pass step one and still collapse in step two. Officers look at the quality of your evidence, not just the count.
This matters when you’re choosing between the two categories. A borderline EB-1A case may look stronger repackaged as an EB-1B if you qualify for both, because the smaller academic pool changes what “top of the field” looks like in the officer’s eyes. It can also cut the other way for a researcher whose international acclaim is unmistakable but whose current employer isn’t in a position to sponsor.
Building the Evidence Package
The form itself, I-140, is straightforward. The real work is the supporting evidence.
Recommendation letters carry a lot of weight, and USCIS reads them carefully. Independent experts who know your work by reputation carry more persuasive force than co-authors praising a joint project, but letters from close collaborators who can describe specific technical details also matter. A strong petition usually includes both. Generic praise hurts. “Dr. Smith is an outstanding researcher” tells USCIS nothing. The letters that move the needle describe specific contributions, explain why they matter to the field, and place your work in context relative to others. If a letter could be written about any competent researcher by swapping in the name, it isn’t strong enough.
For researchers, citation records from databases like Google Scholar or Scopus are concrete evidence of impact. Raw counts alone rarely settle the question. USCIS wants to see how your numbers compare to others in the same field at a similar career stage, so a field-specific benchmark helps the officer read the data.
EB-1B petitions also need formal letters from current or former employers documenting the three-year research or teaching experience. They should describe the specific duties performed and confirm the dates. Vague statements about your role won’t do it.
Any document in a foreign language must include a full English translation, with the translator’s certification that the translation is complete and accurate and that they are competent to translate. Notarization isn’t required, but the certification must include the translator’s name, signature, and address.
Filing Fees
The base filing fee for Form I-140 is $715. On top of that, most petitioners must pay an Asylum Program Fee: $600 for standard employers, $300 for small businesses with 25 or fewer full-time employees and for individual self-petitioners, and $0 for nonprofit organizations and government research institutions. Leaving the Asylum Program Fee questions blank or paying the wrong tier can get the petition rejected outright.
For a faster decision, Form I-907 requests premium processing. USCIS guarantees it will take action on the case within 15 business days or refund the premium processing fee. As of March 1, 2026, the premium processing fee for Form I-140 is $2,965. “Taking action” can mean approval, denial, or a Request for Evidence within that window; it doesn’t guarantee a final decision.
Attorney fees for preparing an EB-1 petition typically range from roughly $5,500 to $17,500, depending on the complexity of the case and the attorney’s experience. Those are separate from government filing fees.
Which One Should You File
The question answers itself for most applicants. If you’re not a professor or researcher, EB-1B isn’t open to you and EB-1A is the only path in this preference. If you are a professor or researcher, you may qualify for both, and the choice turns on a few practical factors.
Choose EB-1A if you want to control the timing, keep your options open on where you work, or don’t have a permanent U.S. job offer in hand. Self-petitioning also insulates the case from anything that might happen to a sponsoring employer.
Choose EB-1B if you have a tenured, tenure-track, or permanent research offer, if your acclaim is strong within academia but thinner outside it, and if you’d rather have your institution handle the filing. The narrower pool can make the “top of the field” showing easier to frame at step two, provided your record supports it.
Some applicants who qualify for both file EB-1A on their own and let their employer separately pursue EB-1B, running two petitions in parallel. Whether that makes sense depends on cost, timing, and how confident you are in each case.
A Note on EB-1C
EB-1 has a third subcategory, EB-1C, for multinational managers and executives. It requires the applicant to have worked abroad for a qualifying organization for at least one year within the previous three years, and to have a permanent managerial or executive job offer with the related U.S. entity, which must have been operating for at least one year before filing. Self-petitioning is not allowed. If you’re comparing options as an executive being transferred to a U.S. affiliate, EB-1C is the category to look at, not EB-1A or EB-1B.
