Visa comparison

US work visas compared: H-1B, L-1, O-1, EB-1A and NIW

Updated: September 15, 2026Author: Alina Kanametova

There are several US work visas and they work differently: H-1B and L-1 rest on an employer, O-1 on proven achievement with no lottery, and EB-1A and EB-2 NIW lead straight to a green card without an employer. One table with all of them below, then the pairwise breakdowns.

Every work and immigrant route in one table

Visa	Who petitions	Lottery	Validity	Green card	For Russians
H-1B	Employer	Yes, annual cap	3 years + 3	Through an employer petition (PERM) or EB-1A / NIW on your own	Interview outside Russia
L-1	Employer (intra-company transfer)	No	L-1A up to 7 years, L-1B up to 5	EB-1C for executives, otherwise as H-1B	A year with the company abroad; interview outside Russia
O-1	Employer or agent	No	Up to 3 years + 1-year extensions	A separate EB-1A / NIW petition, often in parallel	Issued; under reciprocity often a 2-year visa
EB-1A	You (self-petition)	No	Green card	This is the green card: 3 of 10 criteria	Consular stage in a third country or AOS in the US
EB-2 NIW	You (self-petition)	No	Green card	The three Dhanasar prongs; queue by the visa bulletin	As EB-1A
EB-2 / EB-3 via PERM	Employer + DOL labor certification	No	Green card	The classic employer route	As EB-1A

Pairwise breakdowns: which to choose

What the chats ask about a work visa

2×I am in Russia. I have Israeli citizenship (except for my child). I want to submit a petition with premium processing for the EB-2 NIW visa first, and after its approval - for the L1 visa (to open a branch of my company in the USA). Write the algorithm of actions. What are the risks and time frames?
2×L1 visa
2×L-1A visa
1×If I plan to go for an L-1 visa, where should I start?
1×What are my chances of getting approved for an O-1 or L-1 visa (as a temporary visa while waiting for my EB-2 NIW interview)? I can open a company (a branch of my Russian one or a new one) and work there.
1×After my EB-2 NIW petition is approved, can I apply for an O-1 or L-1 visa?

Community answers

How are O-1 and immigrant visas like EB-1A or EB-2 NIW different?: O-1 is a nonimmigrant work visa for people with extraordinary ability, usually with temporary status. EB-1A and EB-2 NIW are immigrant categories that lead to a green card, so their effects on other visas and intentions can differ.
Is O-1 considered a dual intent visa?: O-1 is often seen as more tolerant of immigrant intent, but formally it is not as clearly established as it is for H-1B/L-1. The decision still depends on the officer and the specific circumstances.
What date is used as the priority date for EB-2 NIW and PERM?: For EB-2 NIW, the priority date is usually the I-140 filing date. For PERM-based cases, it is the PERM/labor certification filing date.
How is EB-2 NIW different from regular EB-2?: Regular EB-2 is usually tied to PERM and an employer, while EB-2 NIW allows you to request a waiver of PERM if the applicant's work is of importance to the United States and meets the national interest waiver requirements. For physicians, there are separate NIW options, but the details depend on the employment conditions and location.
Which visa should I choose: J-1, O-1, or H-1B?: The choice depends on the goal, timing, and the applicant's profile. H-1B is limited by an annual filing window and quotas, J-1 may have limits on duration and a possible return requirement, and O-1 is often seen as an option for strong professional cases without a lottery.
For EB-2 NIW with an advanced degree, do you need to prove the exceptional ability criteria?: If the basis is an advanced degree, you usually do not need to separately prove the exceptional ability criteria. But you do need to persuasively address the three NIW prongs: the importance of the endeavor, your ability to advance it, and the benefit of waiving labor certification.

Where people go wrong - from the chats

mistakeIt is risky to treat EB-3 as a formality with a preselected job offer: the labor certification and the education or experience requirements must be real and fit the candidate.
mistakePeople often confuse the requirements of immigrant categories with general student or work visas, for example expecting that education alone will automatically work for an immigrant case without proof of the relevant experience and profile.
mistakeA common mistake is failing to account for the fact that, for work visas, lengthy administrative review can effectively eat into the validity period of the approved petition and reduce the available time to work.

Real timelines named in the chats

Stage	Typically	Note
H-1B: administrative processing after the interview	about 7 months	There is a specific observation where a passport submission request came about 7 months after the interview; H-1B cases waiting since late 2023 without completion are also mentioned.
L-1/L-2: administrative processing after the interview	6 months or more	A long wait for L-1/L-2 is mentioned, with periodic standard responses from the consulate; the review also affected further processing of the immigrant visa.
O-1A: administrative processing after the interview	about 89 days	A single observation for a work visa: the review took about 3 months.
L1: administrative processing under the Technology Alert List after the interview	6 months or more	An L1 case was described involving a PhD/technical field, where AP under a technology alert was already in its 6th month.

Myths and reality

Misconception: The drop in EB-2 NIW approvals in 2025 is often seen as a sign that the category has effectively closed, or that simply having a master's degree or PhD, a business plan, and a described endeavor is enough for approval.

In reality: EB-2 NIW remains available, but approval is not guaranteed by formally meeting the baseline EB-2 requirements. USCIS evaluates the substance and quality of the evidence: the national importance of the proposed endeavor, the applicant's readiness to carry it out, and why waiving labor certification benefits the United States. Having a U.S. PhD, a degree, experience, or a strong occupation can help, but it does not by itself provide priority or replace evidence of impact beyond an employer or personal project.

Myth: The priority date is always counted from the date I-140 is filed.

In reality: For PERM-based categories, the priority date is usually tied to the date the PERM is filed with the Department of Labor. For categories without PERM, such as EB-1 or EB-2 NIW, the priority date usually corresponds to the date USCIS receives the I-140.

Myth: Priority date is the date when the petition will begin to be reviewed or must be reviewed.

In reality: Priority date is usually set when the relevant petition or labor certification is filed and is used to determine immigrant visa availability under the Visa Bulletin. It does not mean the date when the petition will be reviewed or approved.

Myth: For EB-2 NIW, you must prepare a business plan and open your own company in advance.

In reality: A business plan and a company can be useful for an entrepreneurial project, but they are not a universal mandatory requirement. What matters more is proving the substance of the proposed endeavor, its national importance, the applicant's ability to advance it, and why labor certification should be waived.

Myth: For EB-2 NIW, you do not need to prove much because it is a good and relatively simple path.

In reality: EB-2 NIW requires a convincing showing that you qualify for the underlying EB-2 category and the three NIW prongs: the merit and national importance of the project, your ability to advance it, and why waiving the job offer and labor certification is beneficial. The evidence base is critical.

Rules and tips from the chats

tipWhen filing through a consulate in a third country, you should check in advance whether it accepts nonresidents. Some consulates work only with residents or holders of a residence permit, work visa, or student visa.
common questionWhen filing I-140 under EB-1A, people often ask which additional fees apply and whether labor certification PERM is required; the practical rule is that ETA 9089 is usually not required for EB-1A, but current fees should be checked by category and filing date.
common questionPeople often ask in which countries citizens of certain countries can attend an O-1 interview, whether there is a separate line for work visas, and whether it differs from the line for tourist visas.
ruleH-1B is intended for hiring a foreign professional for a position that requires specialized qualifications, not simply for reducing the employer's costs. The visa is based on the existence of a real specialty occupation and the candidate's fit for the requirements.
ruleFor some work visa categories, the visa validity period is usually tied to the validity period of the approved petition. Administrative processing by itself does not guarantee the full maximum visa term.
ruleDifferent visa categories have different waiting risks: DV, H-1B, student, medical, and immigrant visas may depend on a lottery, checks, quotas, or additional procedures.
