You can stay on H-1B past the standard six-year cap if your employment-based green card case has reached one of two milestones set by the American Competitiveness in the Twenty-First Century Act (AC21). A 7th year H-1B extension is available in one-year increments when your labor certification (PERM) or I-140 has been pending for at least 365 days, or in three-year increments when your I-140 is approved but no immigrant visa number is available for your preference category and country of birth.1Office of the Law Revision Counsel. 8 USC 1184 – Admission of Nonimmigrants Which path you qualify for depends entirely on where your green card case stands.
The Two AC21 Extension Paths
Federal law caps H-1B status at six years total, counting any time in H-1B and L-1 status together. AC21 carves out two exceptions, and the practical difference between them is significant.
One-Year Extensions Under Section 106(a)
If a PERM labor certification or I-140 petition has been pending for at least 365 days, you can extend H-1B status one year at a time.2U.S. Citizenship and Immigration Services. Supplemental Guidance Relating to Processing Forms I-140 and I-129 The underlying filing does not have to be approved. It only needs to have been on file for a full year before the requested start date of your extension. You can keep renewing in one-year blocks as long as the green card case stays pending and is not denied or revoked.
One trap catches people off guard. If your I-140 is later approved and a visa number becomes available for your category and country of birth, you generally have to file for adjustment of status or apply for an immigrant visa within one year. Missing that window can end your eligibility for further one-year extensions.
Three-Year Extensions Under Section 104(c)
If your I-140 is already approved but your priority date is not current, you qualify for extensions of up to three years at a time.2U.S. Citizenship and Immigration Services. Supplemental Guidance Relating to Processing Forms I-140 and I-129 Although the statute’s heading references “one-time protection,” USCIS allows multiple three-year extensions under this provision as long as a visa number remains unavailable. Once your priority date becomes current, this path closes.
For workers from India and China, who face the longest employment-based green card backlogs, the three-year path is the more practical route. It reduces the number of renewals, the filing fees, and the risk of a status gap.
Baseline Eligibility
Both paths share some threshold requirements. Your labor certification or I-140 must not have been denied, revoked, or withdrawn. You need to have maintained valid H-1B status throughout your time in the U.S., including compliance with the terms of your original petition. Unauthorized employment or a status violation during the initial six years can sink an extension request.
For the one-year path, the timing element is that 365 days must have passed since the PERM or I-140 was filed by your requested extension start date. For the three-year path, you need an approved I-140 and evidence that no immigrant visa number is currently available for your preference category and country of chargeability.
Recapturing Time Spent Outside the U.S.
Before filing an AC21 extension, look at how much time you spent physically outside the United States during your H-1B years. Days abroad do not count toward the six-year limit and can be recaptured, effectively pushing back when you need an AC21 extension in the first place. Frequent international travelers can recover months this way.
Recapture is not automatic. Your employer must specifically request it in the extension petition and submit documentation of the time abroad. Acceptable evidence includes passport entry and exit stamps, I-94 arrival and departure records, and flight itineraries. USCIS will credit only the days you can document; unsupported claims are dropped without a request for additional evidence.
The calculation runs at the full-day level. Every complete 24-hour day outside the U.S. counts, whether the trip was for business or personal reasons. Any partial day spent in the U.S. does not qualify. Purpose of travel is irrelevant.
Filing the Extension
Your employer files the extension using Form I-129. The petition can be submitted up to six months before your current H-1B status expires, and filing early is strongly recommended because processing times fluctuate.
The petition must include evidence connecting your case to one of the AC21 paths: a copy of the approved I-140 receipt or approval notice, or proof of a labor certification filed at least 365 days before the requested start date. Standard status evidence is also required, including recent pay stubs, W-2s, and a valid passport. Your employer submits a letter describing your job duties, salary, and confirmation that the employment relationship will continue.
Passport validity is easy to overlook. The general rule requires your passport to be valid at least six months beyond your intended stay, though citizens of certain countries are exempt.3U.S. Customs and Border Protection. Six-Month Validity Update Renew early if yours is close to expiring.
The 240-Day Rule
If your employer files the extension before your current status expires and USCIS has not decided it by your expiration date, you may keep working for that same employer for up to 240 days past your status end date while the petition is pending.4Office of Research Services, National Institutes of Health. 240-Day Rule The clock starts the day after your current status expires. You only need proof that the petition was timely filed, not an approval. The 240-day authorization applies only to work for the petitioning employer.
Premium Processing
Premium processing commits USCIS to take action on the petition within 15 business days.5U.S. Citizenship and Immigration Services. How Do I Request Premium Processing Action is not the same as approval; a request for additional evidence resets the clock. The H-1B premium processing fee increased to $2,965 effective March 1, 2026.6U.S. Citizenship and Immigration Services. USCIS to Increase Premium Processing Fees
2026 Filing Fees
- Form I-129 base filing fee: $780 for most employers, $460 for employers with 25 or fewer full-time employees and certain nonprofits.7U.S. Citizenship and Immigration Services. H and L Filing Fees for Form I-129, Petition for a Nonimmigrant Worker
- Asylum Program Fee: $600 for employers with more than 25 full-time equivalent employees, $300 for smaller employers, and $0 for nonprofits.
- ACWIA training fee: $1,500 for employers with 26 or more full-time employees, or $750 for employers with 25 or fewer. Certain nonprofits are exempt.
- Fraud Prevention and Detection fee: $500.
- Premium processing (optional): $2,965 as of March 1, 2026.
The ACWIA training fee and Fraud Prevention fee apply to initial H-1B petitions and certain change-of-employer petitions. If you are extending with the same employer that originally sponsored you, those two fees may not apply, which can reduce the total cost significantly. Immigration attorneys typically charge $500 to $2,500 in legal fees on top of government filing costs.
Your employer cannot pass the ACWIA fee, the Fraud Prevention fee, or expenses related to the I-129 and Labor Condition Application (including attorney fees and premium processing) on to you if doing so would drop your pay below the required wage. The ACWIA and Fraud Prevention fees can never be charged to the employee under any circumstances.8U.S. Department of Labor. Fact Sheet 62H – What Are the Rules Concerning Deductions From an H-1B Workers Pay
If Your I-140 Is Withdrawn
An approved I-140 is the foundation of both AC21 paths, so what happens to it matters. If your employer withdraws the I-140 or goes out of business, you do not automatically lose extension eligibility. USCIS will not revoke an I-140 approval solely because of the employer’s withdrawal or business closure, as long as the petition was approved for at least 180 days before the withdrawal.9U.S. Citizenship and Immigration Services. FAQs for Individuals in H-1B Nonimmigrant Status You also keep your priority date, which protects your spot in the green card queue.
The 180-day protection does not apply if USCIS revokes the I-140 for fraud, material misrepresentation, or a determination that you never qualified. Keep copies of all I-140 approval notices and related correspondence, especially when changing employers.
If You Lose Your Job
Losing employment during a 7th-year extension is disruptive but does not immediately end your status. Federal regulations provide a grace period of up to 60 consecutive days from the date employment ends, or until the end of your authorized validity period, whichever comes first.10eCFR. 8 CFR 214.1 – Requirements for Admission, Extension, and Maintenance of Status You get one grace period per authorized validity period.
During those 60 days you cannot work unless a new employer files an H-1B transfer petition on your behalf. Under H-1B portability, you may begin working for the new employer as soon as the transfer petition is filed, before it is approved. The grace period is meant to give you time to find a new sponsor, change to another status, or prepare to leave.
If your I-140 was approved for at least 180 days before the job loss, you keep your priority date and the I-140 remains valid even though your former employer is no longer sponsoring you. A new employer can then file a fresh H-1B petition and use your existing priority date for green card purposes.
Traveling While the Extension Is Pending
International travel is possible but carries real risk. You must be physically in the U.S. when the extension petition is filed. Once filed, you can travel abroad and re-enter using your existing H-1B visa stamp and I-797 approval notice from your prior petition while the extension is pending.
The risk shows up when your visa stamp has expired. You would then need to apply for a new stamp at a U.S. consulate, and consular processing is never guaranteed. If the extension is denied while you are abroad, re-entry becomes significantly harder. Many attorneys advise against international travel during the extension process unless necessary, especially if your visa stamp is already expired or close to it.
H-4 Spouses and Children
Dependents on H-4 status must extend their own status in step with the principal H-1B holder. They file Form I-539 to request an extension aligned with your new validity period.11U.S. Citizenship and Immigration Services. I-539, Application to Extend/Change Nonimmigrant Status Any gap in your H-1B status affects theirs, so filing everything together is safer.
H-4 spouses may qualify for an Employment Authorization Document if the H-1B principal has an approved I-140 or has been granted H-1B status under AC21’s beyond-six-year provisions.12U.S. Citizenship and Immigration Services. Employment Authorization for Certain H-4 Dependent Spouses Eligible spouses apply on Form I-765.
A recent change matters here. H-4 EAD renewal applications filed on or after October 30, 2025, no longer receive automatic extensions of work authorization while the renewal is pending.13U.S. Citizenship and Immigration Services. Automatic Extensions Based on a Timely Filed Application to Renew Employment Authorization The prior 540-day safety net is gone for new filings. If your spouse depends on an H-4 EAD, file renewals as early as possible and consider premium processing for the underlying H-1B petition to keep the timelines aligned.
