EB‑1A vs EB‑1B vs EB‑1C: Key Differences Explained (2026)

An EB-1A petition is built on individual achievement, and an applicant can file on their own, while an employer must file an EB-1B or EB-1C petition. All three fall under EB-1, the first of five employment-based Green Card categories.

EB-1A requires extraordinary ability in the sciences, arts, education, business, or athletics. EB-1B covers internationally recognized professors and researchers. EB-1C is for multinational managers and executives transferring to a similar role at a related U.S. office.

What are the key differences between EB-1A, EB-1B, and EB-1C?

The differences are in who files, what the applicant must prove, and USCIS approval rates. They also have a lot in common.

All three use Form I-140. None of them require PERM labor certification.

The U.S. caps the number of Green Cards issued each year, so an approved applicant may still have to wait. Each applicant’s place in line is set by their priority date, which for EB-1 is the date the I-140 was filed. Each month, the State Department’s Visa Bulletin publishes cutoff dates by category and country of birth. An applicant can move forward once their priority date is earlier than the cutoff for their category and country. All three EB-1 subcategories share the same line, but wait times can differ significantly by country, especially for applicants born in India or China.

And under all three, a spouse and unmarried children under 21 can get Green Cards as dependents.

How does the EB-1 filing process differ by category?

The categories differ on who files the petition. That determines the evidence, whether a job offer is needed, and which documents go in the file.

Who can file an EB-1A, EB-1B, or EB-1C?

Only EB-1A allows self-petitioning. EB-1B and EB-1C must be filed by a U.S. employer. That employer must provide evidence about itself and the job.

EB-1A. Federal regulations say the applicant, or someone on behalf of the applicant, can file the petition. No employer or job offer is required.

EB-1B. The employer must show:

• It’s offering a tenured or tenure-track teaching job or a permanent research job in the applicant’s field.
• If it’s a private employer, the research unit has at least three full-time researchers and documented accomplishments.
• It can pay the offered wage from the priority date until the applicant becomes a permanent resident.

EB-1C. The employer must show:

• There is a qualifying corporate relationship. The U.S. petitioner must be the same employer that employed the applicant abroad, or a qualifying parent, subsidiary, or affiliate of that foreign company.
• It’s the same company as the employer abroad, or a subsidiary or affiliate of it.
• It has been doing business in the U.S. for at least one year.
• The applicant worked for at least one of the past three years abroad as a manager or executive. For applicants already in the U.S. with the same company, the three years count back from when they entered on nonimmigrant statusa temporary visa. This lookback often applies for L-1 or H-1B holders moving to EB-1.
• It has a U.S.written job offer describing the managerial or executive duties.

What if the applicant changes employers before approval?

• For **EB-1A**, generally nothing changes. The petition depends on the applicant’s record, though they must keep working in the same field.
• For **EB-1B** and **EB-1C**, the petition generally ends with the job since its tied to the petitioning employer. A new employer would need to file a new petition.
• One exception: Once an I-485 has been pending 180 days or more, EB-1B and EB-1C applicants may be able to move to a similar job without a new petition.

Does each EB-1 category require a job offer?

No. EB-1A does not require a job offer or employer sponsor, and applicants may self-petition. In contrast, EB-1B and EB-1C require a qualifying U.S. employer to file the petition and offer the applicant qualifying employment in the United States.

EB-1A does not, but EB-1B and EB-1C do, and the offer must come from the employer filing the petition.

For EB-1A, “neither an offer for employment in the United States nor a labor certification is required.” The applicant still needs “clear evidence” of plans “to continue work in the area of expertise” in the U.S.

That evidence can include:

• Letters from prospective employers
• Contracts or other prearranged commitments
• A statement from the applicant describing plans to keep working in the field

For EB-1B and EB-1C, the job offer is part of the evidence the employer must provide, as covered in the previous section.

What documents does each EB-1 category require?

Each category has its own rules for evidence. EB-1A and EB-1B files center on the applicant’s record in the field, while EB-1C files center on the applicant’s role and the company’s structure.

How do the EB-1A and EB-1B criteria compare?

EB-1B has fewer threshold criteria than EB-1A: applicants generally must satisfy at least two of six criteria, while EB-1A applicants must satisfy at least three of 10 criteria or show a qualifying one-time major achievement. But meeting three EB-1A criteria is not enough by itself. USCIS also conducts a final merits determination to decide whether the evidence, viewed as a whole, shows sustained national or international acclaim and that the applicant is among the small percentage who have risen to the very top of their field.

EB-1B generally has a lower evidence bar than EB-1A. EB-1B applicants must meet at least two of six criteria, while EB-1A applicants must meet at least three of 10 or have received a one-time major award.

The standards behind those criteria differ. EB-1A applicants must show “sustained national or international acclaim” and that they’re “one of that small percentage who have risen to the very top of the field.” EB-1B applicants must be “recognized internationally as outstanding in the academic field.”

Where the criteria overlap

Every EB-1B criterion matches one on the EB-1A list:

• Awards
• Membership
• Published material about the applicant
• Judging others’ work
• Original contributions
• Authorship

EB-1A has four more:

• High salary
• A leading or critical role at a distinguished organization
• Work displayed at artistic exhibitions
• Commercial success in the performing arts

The wording slightly differs across the matching categories. For example, EB-1A accepts “lesser nationally or internationally recognized prizes or awards.” EB-1B requires “major prizes or awards for outstanding achievement in the academic field.”

EB-1B also has requirements EB-1A does not: at least three years of teaching or research, a permanent position, and a U.S. employer to file the petition.

Beyond the criteria

For both categories, USCIS first checks which criteria the evidence meets. It then weighs all the evidence together in a “final merits determination.”

For EB-1B, the USCIS policy manual says meeting “at least two types of initial evidence does not, in itself, establish” eligibility. The EB-1A chapter says the same about meeting three criteria.

Which EB-1 category is the applicant eligible for?

Eligibility starts with the applicant’s job situation. The key questions are whether a qualifying U.S. employer is involved and what role it’s offering.

• No qualifying U.S. employer: EB-1A is the only EB-1 category available. The applicant can file alone, based on their record in the field.
• A permanent research or teaching offer: EB-1B may fit if the applicant meets at least two of six criteria and has three years of teaching or research experience. Some applicants in this group may also qualify for EB-1A.
• A manager or executive at a multinational company: EB-1C may fit if the applicant spent at least one of the past three years in a managerial or executive role at a related company abroad.

Ask an immigration attorney whether an applicant's record meets a category’s standard.

Can I apply for an EB-1 Green Card while on another visa?

Many EB-1 applicants already live and work in the U.S. on a temporary visa, and some of those visas line up closely with an EB-1 category.

• **L-1A to EB-1C**: Both require a managerial or executive role at a related company abroad, making EB-1C a common next step for L-1A managers and executives.
• O-1A to EB-1A: The evidence often lines up, since several criteria overlap.
• **H-1B to EB-1B or EB-1C**: H-1B researchers at universities may fit EB-1B. H-1B managers who spent a year at a related company abroad may fit EB-1C.
• J-1 or **F-1 to EB-1B**: Visiting researchers and postdocs may move on to an EB-1B. Some J-1 holders must first meet a two-year home residency requirement or get a waiver.

H-1B, L-1, and L-1 allow “dual intent,” which means filing a Green Card petition isn’t grounds to deny an extension or a change of status.

What if the applicant is eligible for two categories?

Some applicants fit more than one EB-1 category. The likeliest overlap is EB-1A and EB-1B since they share some criteria.

Here are some profiles that may fit two categories:

• A university researcher with international recognition may fit EB-1B through a permanent faculty or research role, or EB-1A based on their record alone.
• An industry scientist at a private research lab may fit EB-1B if the lab meets the employer rules, or EB-1A.
• A multinational executive with acclaim in their field may fit EB-1C through the company, or EB-1A on their own.

An applicant can file more than one I-140. An approved I-140 generally keeps its priority date for later EB-1, EB-2, or EB-3 petitions. That means an earlier approval can hold the applicant’s place in line for a Green Card.

There are trade-offs. EB-1A doesn’t require a job offer, but has a higher evidentiary bar. EB-1B and EB-1C depend on an employer. USCIS approves EB-1B and EB-1C at much higher rates than EB-1A.

The right path depends on the applicant’s record and role.

Manifest Law can work with an individual preparing a self-petitioned EB-1A and with employers filing EB-1B and EB-1C petitions for their teams. An attorney can review the record, assess which categories apply, and build the right filing strategy. Talk to an EB-1 attorney to plan the next step.

Frequently asked questions

Can I switch employers after getting my EB-1 Green Card?

EB-1A holders aren’t tied to an employer, though their petition relied on plans to keep working in their field. EB-1B and EB-1C holders can also change jobs after approval, but they must have truly intended to take the sponsored job when the Green Card was granted.

How long do I need to stay in the U.S. after getting my EB-1 Green Card?

There is no specific minimum number of days you must remain in the U.S. after becoming a permanent resident. However, a Green Card is intended for people who make the United States their permanent home, and extended or frequent absences can raise questions about whether you have abandoned your permanent residence. If you expect to remain outside the U.S. for an extended period, you may apply for a re-entry permit by filing Form I-131 before leaving the country.

There’s no set minimum, but USCIS uses an absence of more than a year as a general guide when deciding whether someone has given up permanent residence. Green Card holders planning a longer trip can apply for a re-entry permit with Form I-131 before they leave.

Can I apply for EB-1 from outside the United States?

Yes. The I-140 can be filed while the applicant lives abroad. After approval the case moves to the National Visa Center, then to a Form DS-260 application and an interview at a U.S. embassy or consulate.

Can letters of recommendation help my EB-1 case?

Yes. USCIS doesn’t require letters of recommendation for EB-1, but letters from independent experts in the field can explain the applicant’s impact and reputation, especially for EB-1A and EB-1B.

Can I apply under multiple Green Card categories at the same time?

Yes. An applicant who qualifies for more than one category can have several I-140 petitions pending at once. Pairing EB-1A and EB-2 NIW applications is common.

Is EB-1B easier than EB-1A?

EB-1B generally has a lower evidence bar: two of six criteria instead of three of 10. But it requires a qualifying employer and a permanent research or teaching position.

Who qualifies for EB-1A vs. EB-1B?

EB-1A is for people at the very top of their field who have sustained national or international acclaim, and they can file on their own. EB-1B is for internationally recognized professors and researchers with three years of experience and a permanent U.S. job offer. See the comparison above.
