H-1B to Green Card: PERM, I-140 and the Priority Date Queue
Approximately 140,000 employment-based immigrant visas a year, and that figure includes spouses and children. Here is the three-stage mechanism — PERM, I-140, the queue — stated as USCIS and DOL state it.

Almost every Indian professional on an H-1B is really planning for something else: the green card at the end of it. The H-1B is temporary by design — six years, with carve-outs. Permanent residence is a separate system with its own forms, its own queue, and its own arithmetic, and the single most expensive mistake is treating the two as one continuous process.
This is what the employment-based green card actually consists of, in the order it happens, using only what USCIS and the Department of Labor state.
The supply: 140,000 a year, split five ways
USCIS states that approximately 140,000 immigrant visas are available each fiscal year for people immigrating on the basis of their job skills — and that figure includes their spouses and children. It is not 140,000 workers. A married applicant with two children consumes four numbers.
Those 140,000 are divided among five preference categories:
| Category | Who it is for | Individual labor certification required? |
|---|---|---|
| EB-1 | Extraordinary ability in the sciences, arts, education, business or athletics; outstanding professors and researchers; certain multinational executives and managers | No |
| EB-2 | Members of the professions holding advanced degrees, or persons of exceptional ability in the arts, sciences or business | Yes, unless filed with a Schedule A designation or a national interest waiver request |
| EB-3 | Professionals, skilled workers, and other workers | Yes, unless filed with a Schedule A designation |
| EB-4 | Certain special immigrants, including certain religious workers | No |
| EB-5 | Investors placing $1,050,000 — or $800,000 in a targeted employment area — into a new commercial enterprise employing at least 10 full-time US workers | No |
If your role is executive or managerial at a multinational, note that EB-1 covers certain multinational executives and managers and needs no labor certification — see the L-1 route. For the overwhelming majority of H-1B holders the live categories are EB-2 and EB-3, and both of those normally require a labor certification. That is where the process begins.
Stage one: PERM labor certification
Before the employer can file an immigrant petition for an EB-2 or EB-3 worker, it must generally obtain a permanent labor certification from the Department of Labor. DOL describes what the certification establishes:
- that there are insufficient available, qualified, able and willing US workers to fill the position at the prevailing wage rate or higher; and
- that employing a foreign worker will not adversely affect the wages and working conditions of similarly employed US workers.
DOL is explicit about whose process this is: "The filing of applications is the responsibility of the employer, not the employee." You are the beneficiary of PERM; you are not the applicant. You cannot file it, you cannot move it along, and you cannot take it with you.
The application is Form ETA-9089. For applications filed on or after 1 June 2023, it goes through DOL's Foreign Labor Application Gateway (FLAG) system, and what reaches USCIS is an approved and signed ETA-9089 Final Determination.
Two ways to skip PERM
USCIS identifies two exceptions to the individual labor certification requirement:
- Schedule A occupations. DOL has already determined there are not sufficient US workers in these, so no DOL-approved certification is needed. There are two groups. Group I is professional nurses and physical therapists. Group II is people of exceptional ability in the sciences or arts — including college and university teachers — and immigrants of exceptional ability in the performing arts.
- National interest waiver (NIW), EB-2 only. The petition asks that the job offer, and therefore the labor certification, be waived because it is in the national interest of the United States.
The national interest waiver, as USCIS actually judges it
NIW is the route people most often misunderstand, so it is worth stating precisely. USCIS notes that the qualifying endeavours are not defined by statute; the agency instead weighs three factors, and you may self-petition — no employer sponsor, no DOL labor certification.
- Prong 1 — substantial merit and national importance. USCIS stresses that "endeavor" is more specific than the general occupation. You must describe what you specifically propose to do, not what people in your job title generally do.
- Prong 2 — you are well positioned to advance it. Education, skills, knowledge, record of success in similar efforts, and a detailed plan you actually developed.
- Prong 3 — on balance it benefits the US to waive the job offer and labor certification. Explain why obtaining a labor certification would be impractical given your qualifications or endeavour.
USCIS also publishes, bluntly, what does not work — and these examples are the ones to read twice:
- Benefits to a specific employer alone are "not sufficiently relevant" to national importance, even if the employer has a national footprint.
- Classroom teaching without broader implications for a field or region generally does not rise to national importance.
- Working in an occupation with a national shortage — or consulting for others who want to — is insufficient on its own. The same point is repeated under prong 3: a national labour shortage alone does not satisfy it.
- A software engineer adapting their employer's code for various clients "will have difficulty demonstrating the national importance of that endeavor, absent additional broader impacts supported by specific evidence."
- An entrepreneur cannot establish national importance solely by opening a consulting firm in a nationally important occupation.
Conversely, USCIS gives the shape of what does work: a person developing a drug may show national importance through prospective public health benefits rather than employer profit; a person developing a technology may show it through widespread interest in adoption or licensing, a novel manufacturing or operational process, or impact on how similar technology develops elsewhere.
Stage two: Form I-140
With certification in hand (or an exception applied), the employer files Form I-140, Immigrant Petition for Alien Worker. For NIW cases, you may file the I-140 on your own behalf.
There is a deadline here that quietly destroys cases. USCIS states that to preserve the priority date, the petitioner must file the I-140 within 180 days of the DOL approval date on the labor certification — otherwise the labor certification is no longer valid. Everything stage one bought is lost.
If the I-140 is approved, your spouse and unmarried children under 21 may be eligible to apply with you or after you. In EB-2 the derivative classifications are E-21 for the spouse and E-22 for children.
Stage three: the queue, which is where India sits
This is the stage no form can speed up. USCIS sets it out plainly: employment-based preference visas are numerically limited, each sub-category receives a set percentage by law, and "there are limits to the percentage of visas that can be allotted based on an immigrant's country of chargeability (usually the country of birth)."
When demand exceeds supply for a category and country, a queue forms. The Department of State then declares that category and country oversubscribed and imposes a cut-off date to keep allocation within the statutory limits.
Your priority date
Your place in that queue is your priority date, and where it comes from depends on your category:
| Situation | Priority date is the date… |
|---|---|
| Category requires a DOL labor certification (EB-2, EB-3) | DOL accepts the labor certification application for processing |
| Category does not require labor certification (EB-1, NIW) | USCIS accepts Form I-140 for processing |
| EB-4 special immigrant | USCIS accepts Form I-360 for processing |
| EB-5 investor | USCIS accepts Form I-526 for processing |
USCIS says you can find your priority date on the Form I-797, Notice of Action for the petition filed on your behalf.
Reading the Visa Bulletin
The monthly Visa Bulletin from the Department of State carries two charts:
- Application Final Action Dates — when a visa can actually be issued or status actually adjusted.
- Dates for Filing Applications — when applicants should be notified to assemble and submit documents.
Which chart you may use is not your choice. USCIS determines it: when there are more visas available for the fiscal year than known applicants, you may use the Dates for Filing chart; otherwise you must use Final Action Dates. USCIS states that unless its Adjustment of Status Filing Charts page indicates otherwise, you must use Final Action Dates to determine when you can file Form I-485.
A visa is available when your priority date is earlier than the cut-off shown for your category and country. A category marked "C" is current — visas are immediately available to all qualified applicants.
What keeps you legal while you wait
The H-1B is normally capped at six years: up to three years on admission, extendable by up to three more. (If you change employers during that window, the rules are in our guide to H-1B portability and the 60-day grace period.) Two provisions let you go beyond that, and both exist precisely because of the backlog:
- 8 CFR 214.2(h)(13)(iii)(E) — you may be eligible for extension beyond the sixth year if you are the beneficiary of an approved EB-1, EB-2 or EB-3 immigrant petition and would be eligible for that status but for the per-country or worldwide limits. The petitioner must show the visa is unavailable as of the filing date. USCIS may grant these in up to three-year increments until it finally decides to revoke the immigrant petition, or to approve or deny the immigrant visa or adjustment application.
- 8 CFR 214.2(h)(13)(iii)(D) — you may be eligible for extension beyond the sixth year if at least 365 days have passed since a labor certification was filed.
Those two rules are the reason the practical advice is always the same: start PERM early. Not because it makes the green card arrive sooner — it does not — but because the 365-day clock is what keeps your status alive while the queue does its work.
The order that actually matters
- Employer files PERM (ETA-9089 via FLAG). Your priority date is set the day DOL accepts it.
- DOL certifies. The 180-day clock to file I-140 starts.
- Employer files I-140. Priority date preserved. Approval unlocks H-4 EAD eligibility for your spouse and the 3-year extensions above.
- You wait for your priority date to become current for your category and country of chargeability.
- File Form I-485 (or consular process) when the applicable chart permits.
What we have deliberately not published
You will see specific wait-year figures for India EB-2 and EB-3 quoted everywhere. We are not publishing them, because they are projections derived from bulletin movement, not numbers any agency states, and they change direction. The same applies to current cut-off dates and to filing fees, which are set in the USCIS fee schedule and revised.
Check the Visa Bulletin for the month you care about, the USCIS filing charts for which chart applies, and the G-1055 fee schedule for what anything costs. Everything above is the mechanism — the mechanism is what stays true.
