The I-140 Immigrant Petition Explained

Form I-140, Immigrant Petition for Alien Worker, is the petition that asks U.S. Citizenship and Immigration Services (USCIS) to classify a foreign national as eligible for an employment-based green card. For most workers it is filed by a U.S. employer, usually right after the employer completes a labor certification (PERM) with the Department of Labor. For a smaller group of people — those seeking EB-1A "extraordinary ability" or a National Interest Waiver (NIW) under EB-2 — the worker can file the I-140 alone, without an employer or a labor certification. Approval of the I-140 does not by itself grant a green card; it establishes that the person qualifies for a visa category and locks in a "priority date" that determines when a visa number becomes available.

Who files the I-140, and for which category

• EB-1A (extraordinary ability), EB-1B (outstanding professor/researcher), EB-1C (multinational manager/executive): EB-1B and EB-1C require an employer petitioner; EB-1A can be self-petitioned. None of the EB-1 subcategories require a PERM labor certification.
• EB-2 (advanced degree or exceptional ability): Normally requires an employer and an approved PERM labor certification. The exception is the National Interest Waiver (NIW), where the worker can self-petition and both the labor certification and the job offer are waived because the work is found to be in the national interest.
• EB-3 (skilled workers, professionals, other workers): Requires an employer and an approved PERM labor certification.

When a labor certification is required, the employer must file the I-140 within a set window after PERM approval by the Department of Labor — the certification is valid for a limited period and expires if it isn't submitted to USCIS in time. If that window is missed, the labor certification is no longer usable and the process generally has to start over with the Department of Labor. Confirm the current PERM validity window directly on the Department of Labor's PERM program page before relying on any specific number.

The priority date: why it is the most important thing on the form

The priority date is, in effect, the worker's place in line for a green card. For categories that require PERM, the priority date is the date the labor certification application was accepted for processing by the Department of Labor — not the date the I-140 is filed. For self-petitioned categories with no labor certification (EB-1A, NIW), the priority date is the date USCIS receives the properly filed I-140.

Once a worker's I-140 is approved, that priority date is generally retained for use with a later I-140 petition — for example, if the person changes employers and a new employer files a fresh I-140 — as long as the earlier approval was not revoked for fraud, willful misrepresentation, or a material USCIS error. Whether a visa is actually available to file the final green card step (adjustment of status or consular processing) depends on the priority date's position relative to the Department of State Visa Bulletin, which is published monthly and is the only reliable source for current wait times by category and country of birth.

The "ability to pay" requirement

For employer-sponsored petitions, the employer must prove it can pay the offered wage from the priority date until the worker obtains permanent residence. Under federal regulation, the standard evidence is one of: copies of the employer's federal tax returns, audited financial statements, or annual reports. If the employer already pays the worker at or above the offered wage, payroll records showing that can also satisfy the requirement. Employers with 100 or more workers may instead submit a statement from a financial officer attesting to the ability to pay. USCIS can request additional evidence — such as profit-and-loss statements, bank records, or personnel records — and often issues a Request for Evidence when a company's finances are unclear, seasonal, or the offered wage is a large share of total payroll. This is one of the most common reasons I-140 petitions receive extra scrutiny, especially for smaller employers.

Premium processing

Premium processing (requested on Form I-907) is a paid option that gets USCIS to take action on the I-140 — an approval, a denial, or a Request for Evidence — within a guaranteed number of business days, rather than the standard queue. It is available for most I-140 categories, including EB-1 and EB-2 (the EB-2 NIW category was added to premium-processing eligibility in 2023). Premium processing speeds up the adjudication decision only; it does not change the priority date, does not make a visa number available sooner, and does not skip the Visa Bulletin. The current fee and the guaranteed number of business days change over time, so check the current figures directly on USCIS's Form I-907 page before budgeting or planning around them.

Job portability under AC21 (INA 204(j))

The American Competitiveness in the Twenty-First Century Act (AC21) lets some workers change jobs without losing the benefit of an already-filed I-140. The rule applies once the worker's Form I-485 (adjustment of status application) has been pending for 180 days or more, and only if the new job is in the "same or similar" occupational classification as the job described in the original I-140. USCIS looks at factors including matching Standard Occupational Classification (SOC) codes, job duties, required skills, and salary level — it is a totality-of-the-circumstances test, not a single checkbox. The move is documented on Form I-485 Supplement J, filed with USCIS. If the request is accepted, the approved I-140 remains valid, the worker keeps the original priority date, and the case is not restarted from scratch — even though the employer or job has changed.

Portability under AC21 requires an already-approved I-140 and a pending I-485 that has cleared the 180-day mark. It does not apply to workers who haven't yet filed an I-485, and it does not apply while the I-140 itself is still pending. Anyone considering a job change before those conditions are met should get case-specific advice before acting, since an unsupported job change can jeopardize the entire petition.

What happens after I-140 approval

Approval of the I-140 means USCIS agrees the worker is eligible for the visa category — it is a necessary step, not the final one. Depending on where the priority date falls in the Visa Bulletin and where the worker is located, the next step is either:

• Adjustment of status (Form I-485) if the worker is already lawfully in the United States, or
• Consular processing through the National Visa Center and a U.S. embassy or consulate if the worker is abroad.

Neither step can be filed — or, if already filed, can move forward to a green card — until a visa number in that category and country of birth is currently available under the Visa Bulletin.

What to do

1. Confirm which category fits (EB-1, EB-2/NIW, or EB-3) and whether a PERM labor certification is required.
2. If PERM is required, track the DOL certification date carefully and file the I-140 within the certification's validity window — don't let it lapse.
3. Gather ability-to-pay evidence (tax returns, financial statements, or payroll records) before filing, especially for smaller employers.
4. Decide whether premium processing is worth the current fee for your situation, and check the current fee and timeframe on the official I-907 page.
5. Once approved, monitor the Visa Bulletin each month to know when you can file (or continue) the green card step.
6. If you plan to change jobs while a green card case is pending, confirm your I-485 has been pending 180+ days and that the new job is in the same or similar occupation before making the move, and file Form I-485 Supplement J.

Deadlines to watch

The clearest hard deadline in this process is the PERM certification's limited validity window for filing the I-140 — missing it means starting the labor certification over. There is no fixed deadline to file an I-140 for self-petitioned categories like EB-1A or NIW, but visa availability, current program rules, and personal circumstances (such as maintaining status) can create real time pressure. Always confirm current deadlines and requirements directly with USCIS or the Department of Labor rather than relying on outside estimates.

Frequently asked questions

Does I-140 approval mean I have a green card?

No. It means USCIS has approved the underlying employment-based classification and set your priority date. You still need a visa number to become available under the Visa Bulletin and then need to complete adjustment of status or consular processing.

Can I change employers after my I-140 is approved?

Sometimes. Under AC21/INA 204(j), you may be able to change jobs and keep the approved I-140 and your priority date if your Form I-485 has been pending 180 days or more and the new job is in the same or similar occupational classification. Changing jobs before those conditions are met can put the petition at risk.

What if my employer's I-140 is still pending when I get a new job offer?

AC21 portability applies to an approved I-140 with a pending I-485 of 180+ days — not to a pending I-140. Get advice specific to your timing before changing jobs.

How does premium processing help me?

It only speeds up when USCIS decides your I-140 (approval, denial, or a Request for Evidence) within a guaranteed number of business days. It does not move up your place in the Visa Bulletin or guarantee approval.

Can I file my own I-140 without an employer?

Only in certain categories — mainly EB-1A (extraordinary ability) and EB-2 National Interest Waiver — where no employer sponsor or labor certification is required. Most EB-2 and all EB-3 cases require an employer petitioner and an approved PERM labor certification.
