EB-1A vs. EB-1B Green Cards: Key Facts You Need to Know
When exploring employment-based immigration options, two of the most prestigious visas are the EB-1A (Extraordinary Ability) and EB-1B (Outstanding Professors and Researchers) green cards. Both fall under the EB-1 category, known for faster processing times, premium processing eligibility, and exemption from labor certification. However, each visa serves a different purpose and applies to different types of applicants.
At Green Card Link, its immigration attorneys help professionals, researchers, and extraordinary individuals navigate the complexities of EB-1 petitions to achieve their permanent residency goals.
Similarities Between EB-1A and EB-1B
- EB-1 Priority Category – Both EB-1A and EB-1B green cards benefit from faster processing than many other employment-based green cards.
- No Labor Certification (PERM) Required – Unlike other green card categories, neither EB-1A nor EB-1B applicants must go through the lengthy PERM process, which can delay applications by years.
- Premium Processing Eligible – Applicants may choose expedited adjudication of the I-140 petition for an additional fee.
- High Standard of Evidence – Both categories require extensive documentation to prove international recognition and distinguished achievements in the applicant’s field.
Key Differences Between EB-1A and EB-1B
Criteria | EB-1A: Extraordinary Ability | EB-1B: Outstanding Professors/Researchers |
Job Offer Requirement | Not required. Self-petition allowed. | Required. Employer sponsorship necessary. |
Eligibility Scope | Open to all fields: science, business, arts, education, athletics. | Restricted to academic and research fields only. |
Experience Requirement | No minimum years of experience required. | Must show at least three years of teaching or research experience. |
Proof Required | Must meet 3 out of 10 USCIS criteria or provide proof of a one-time major award (e.g., Nobel Prize). | Must provide proof of international recognition and meet 2 out of 6 USCIS criteria. |
Ease of Approval | More challenging due to self-petition and higher evidentiary burden. | Comparatively easier with employer backing and strong academic record. |
Processing Time | Generally 3–4 months with premium processing. | Typically 6+ months, depending on USCIS caseload. |
EB-1A: Extraordinary Ability
The EB-1A green card is designed for individuals who have risen to the very top of their field. Applicants must demonstrate sustained national or international acclaim and prove that their work has been recognized as significant within their discipline.
EB-1A Requirements
To qualify, applicants must either:
- Show proof of a major internationally recognized award (such as a Nobel Prize, Pulitzer, or Grammy); or
- Meet at least three out of ten USCIS criteria, which may include:
- Authorship of scholarly publications in reputable journals
- Internationally or nationally recognized awards and honors
- Significant contributions to the field (scientific, scholarly, or artistic)
- Membership in elite professional organizations with rigorous admission standards
- Published material about the applicant in major media or trade publications
- Serving as a judge or peer reviewer in the applicant’s field
- Playing a critical or leading role in distinguished organizations
- Display of work in professional exhibitions
- Evidence of high salary or compensation compared to peers
- Commercial success in performing arts
- Authorship of scholarly publications in reputable journals
Because EB-1A allows self-petitioning without a job offer, it provides flexibility and independence for applicants, but also comes with a higher burden of proof.
EB-1B: Outstanding Professors and Researchers
The EB-1B green card is designed for professors and researchers who have earned international recognition for outstanding academic contributions.
EB-1B Requirements
- Must demonstrate at least three years of teaching or research experience in the academic field.
- Must have a permanent job offer from a U.S. employer, which can be:
- A university or institution of higher education
- A private company with a strong research track record employing at least three full-time researchers
Applicants must meet at least two of six USCIS criteria, including:
- Major awards for outstanding achievement
- Membership in associations requiring outstanding accomplishments
- Published material in professional publications about the applicant’s work
- Authorship of scholarly books or articles in international journals
- Original scientific or scholarly contributions
- Participation as a judge of the work of others in the academic field
Because EB-1B requires employer sponsorship, it is often considered more accessible for qualified academics compared to the more stringent EB-1A.
EB-1B: Outstanding Professors and Researchers
Both EB-1A and EB-1B petitions follow similar timelines. On average, the I-140 petition takes 6–8 months to process. However, premium processing can reduce this to 15 business days.
After approval, applicants must check their priority date against the U.S. Department of State’s monthly Visa Bulletin. Most EB-1 categories remain current, but backlogs often apply to applicants from India and China.
Choosing Between EB-1A and EB-1B
- Choose EB-1A if you seek independence, do not have a permanent U.S. job offer, and can demonstrate extraordinary ability across a wide range of fields.
- Choose EB-1B if you are an academic or researcher with a strong publication record, international recognition, and employer sponsorship.

If you are ready to pursue an EB-1 petition, the experienced immigration attorneys at Green Card Link can help evaluate your eligibility, build a strong evidence portfolio, and guide you through every step of the process.
EB-1B Green Card: A Complete Guide for Outstanding Professors and Researchers
The EB-1B green card is designed specifically for outstanding researchers and professors who can demonstrate international recognition for their achievements in academia. Unlike broader categories such as the EB-1A, which applies to extraordinary individuals in business, science, education, arts, or athletics, the EB-1B is limited to candidates who excel in research or teaching at a distinguished level.
USCIS outlines a clear set of evidence that applicants must provide to establish eligibility, and this pathway is a strong option for individuals who have built a substantial record of scholarly contributions.
EB-1B vs. EB-1A: Key Differences
While the EB-1A green card allows self-petitioning—meaning applicants do not need a U.S. employer—the EB-1B does not. To qualify, you must have a job offer from a sponsoring U.S. employer, who will also take responsibility for filing the Form I-140 petition on your behalf.
This employer sponsorship requirement comes with both advantages and limitations. On one hand, the employer covers the I-140 filing fee; on the other hand, your work authorization in the U.S. is tied to that employer, which can limit professional flexibility compared to the EB-1A.
EB-1B Eligibility Requirements
To be eligible for the EB-1B, you must:
- Have at least three years of experience in teaching or research in your academic field.
- Be coming to the United States with the intention of obtaining tenure, tenure-track employment, or a comparable long-term research position at a U.S. university or research institution.
In addition, applicants must provide evidence of at least two of the following:
- Receipt of internationally recognized awards or prizes for excellence in the field.
- Service as a judge of peer research, either individually or on a panel.
- Authorship of scholarly books or articles published in leading journals.
- Published material authored by others that specifically highlights your work in reputable outlets.
- Demonstrated significant contributions to your area of expertise.
- Membership in professional organizations that require outstanding achievements as a condition of entry.
At its core, this evidence is intended to prove that you have made outstanding achievements in your academic discipline. Additional documentation outside this list may also be accepted, and it is best to consult with an immigration attorney at Green Card Link to ensure the strongest possible presentation of your qualifications.
EB-1A vs. EB-1B: Which Should You Choose?
Some individuals may qualify for both EB-1A and EB-1B green cards. In such cases, pursuing the EB-1A often provides more flexibility, as it does not require employer sponsorship and allows applicants to work freely across institutions or projects. The EB-1A also encompasses a broader range of fields beyond academia.
However, the EB-1B may be the easier route if you already have employment with a respected U.S. institution and a strong record of research and publications. Since the sponsoring employer pays the I-140 filing fee, this option may also be less expensive than self-petitioning under the EB-1A.
Both categories, however, share similar processing times and filing costs, and both require extensive evidence to prove eligibility.
