What are USA H-1B and O-1 and who they suit
H-1B and O-1 are two common work (non-immigrant) visas for coming to the USA to work, after which you may transition to a Green Card. According to the U.S. Citizenship and Immigration Services (USCIS), H-1B is for specialty occupations requiring a university degree; O-1 is for individuals with extraordinary achievement.
Unlike EB-3, EB-2 or EB-5 (which grant a Green Card directly), H-1B and O-1 grant temporary work status. However, both permit “dual intent,” meaning you can work while also pursuing an immigration case through EB-1, EB-2 or EB-3.

- Allows you to work while pursuing an immigration case (dual intent)
- O-1 has no numerical cap and no selection process
- Can transition to a Green Card via EB-1 / EB-2 / EB-3
How H-1B and O-1 differ
The two visas target two different groups. M2W specialists advise on the one that fits your profile and goals.
H-1B
Specialty Occupation
For specialty occupations requiring at least a bachelor’s degree in the relevant field. Subject to an annual quota and a registration selection round.
O-1
Extraordinary Ability
For individuals with extraordinary achievement in the sciences, arts, business, education or athletics. No quota, no selection process.
The H-1B visa application process
H-1B has an annual registration and selection round. From fiscal year 2027, the selection round shifts to prioritizing higher wages instead of a random lottery.
Step 1 — H-1B registration
The employer electronically registers the worker during the registration period (typically March each year).
Step 2 — Selection under the quota
USCIS selects cases within the quota of 85,000/year. From FY2027, cases with higher wages are prioritized instead of a random lottery.
Step 3 — File the LCA and Form I-129
The employer obtains a Labor Condition Application (LCA) from the Department of Labor, then files Form I-129 for the selected worker.
Step 4 — Receive the visa & immigration roadmap
Once I-129 is approved, the worker receives H-1B status and can begin a Green Card case via EB-1/EB-2/EB-3.
The pathway from work visa to Green Card
Both H-1B and O-1 permit “dual intent,” so while you are working you can pursue an immigration case. This is how many professionals both stabilize their careers and build their Green Card case.
- Transition to EB-1 if you meet the extraordinary-ability or multinational-manager criteria
- Transition to EB-2 NIW if you hold an advanced degree and your work serves the national interest
- Transition to EB-3 if sponsored by an employer through PERM
Comparing H-1B, O-1 and direct EB-3 immigration
H-1B/O-1 are temporary work visas; EB-3 grants a Green Card directly. Many people combine both routes.

Frequently asked questions about H-1B and O-1
Is the H-1B still a random lottery?
From fiscal year 2027, USCIS replaces the random lottery with a selection mechanism that prioritizes applications with higher wages. The quota remains 85,000/year.
How does O-1 differ from H-1B?
O-1 is for individuals with exceptional achievements, with no quota and no selection round; H-1B is for specialty positions requiring a bachelor's degree and has an annual quota.
Do the H-1B or O-1 lead to a Green Card?
Yes. Both allow “dual intent,” so while working you can pursue an immigration application through EB-1, EB-2 NIW, or EB-3.
Can your family come with you?
Yes. Dependents of H-1B holders come under the H-4 category, and those of O-1 holders under the O-3 category. When transitioning to a Green Card, the whole family settles together.
Should I choose a work visa or direct immigration?
It depends on your profile and goals. If you have an employer and want a Green Card sooner, EB-3 may be a better fit; if you want to work in the U.S. first, H-1B/O-1 is a stepping stone. M2W advises on the optimal pathway.
Should you take H-1B, O-1 or direct immigration?
Each route suits a different type of profile. M2W specialists will review your profile and advise on the optimal pathway between a work visa and direct immigration.
