H-1B Extension: Processing Time, 240-Day Rule and Six-Year Limit

An H-1B worker is generally admitted for up to 3 years and can extend that stay for up to another 3 years, for a standard total limit of 6 years, according to U.S. Citizenship and Immigration Services (USCIS). Your employer files Form I-129 before your current Form I-94 expires. A timely filing triggers the automatic 240-day work authorization rule while the case is pending.

With an approved Form I-140 or a labor certification or immigrant petition pending at least 365 days, you can also extend H-1B status beyond the 6-year limit.

How long can you extend H-1B status?

USCIS admits H-1B specialty occupation workers for an initial period of up to 3 years. Your employer can apply to extend that initial admission for up to another 3 years, which brings the general maximum stay in H-1B visa classification to 6 years.

Founders and majority owners have a shorter validity window. Under the December 18, 2024 H-1B modernization final rule, if you hold a controlling interest in the petitioning company (owning more than 50% or having majority voting rights), your initial petition and your first extension are each limited to up to 18 months. As a beneficiary owner, you must still perform specialty occupation duties a majority of the time.

When you apply to extend petition validity with the same employer and the same underlying facts, the USCIS Policy Manual tells officers to defer to the prior approval where appropriate. An officer should not defer if there was a material error on the prior approval, a material change in circumstances or eligibility, or new adverse material information, and must get supervisory approval before deviating from a prior approval.

If you reach 6 years and do not qualify for an employment-based green card exception, you can only start a new 6-year H-1B period after you have been outside the United States for 1 continuous year (brief trips for business or pleasure do not interrupt that year). Starting a new 6-year period makes you subject to the annual H-1B numerical cap again if your job is cap-subject.

When and how your employer files Form I-129

Your authorized stay is controlled by the expiration date in the lower right-hand corner of your Form I-94, Arrival-Departure Record, not the visa stamp in your passport. Even if your Form I-797 approval notice has a later end date, if your Form I-94 expires earlier, your employer must file an extension of stay on Form I-129 before your Form I-94 date runs out.

USCIS recommends applying to extend your stay at least 45 days before your Form I-94 expires, and the petition must be received before your current status ends. You cannot file Form I-129 yourself, and you must be physically present in the United States when your employer files the extension of stay petition. To qualify, you must have been lawfully admitted, hold valid nonimmigrant status, have not violated your status or committed disqualifying crimes, and keep a valid passport for the duration of your stay.

Starting November 9, 2026, USCIS accepts only the 09/09/26 edition of Form I-129 (until then, the 02/27/26 edition is also accepted). For petitions postmarked or submitted electronically on or after September 9, 2026, covered employers (50 or more U.S. employees with more than 50% in H-1B, L-1A, or L-1B status) must also submit the statutory 9-11 Response and Biometric Entry-Exit Fee whenever the petition seeks an extension of status.

1. Step 1: Check your Form I-94 expiration date, passport validity, and whether H-4 dependents (spouse and unmarried children under 21) need extensions.
2. Step 2: Employer gets a certified Labor Condition Application (LCA), Form ETA-9035/9035E, from the Department of Labor (DOL), attesting to actual or prevailing wages, working conditions, no strike or lockout, and notice posting.
3. Step 3: Employer completes Form I-129 (including Part 6, the controlled technology release certification) and signs it with a valid signature.
4. Step 4: Package H-4 family applications together if needed. If your dependent files Form I-539 (and Form I-765 for an H-4 spouse EAD) in the same package, at the same time and location as your Form I-129, USCIS adjudicates them together after reviewing your Form I-129.
5. Step 5: Pay each form's filing fee separately. For paper filings, USCIS no longer accepts checks or money orders unless exempt via Form G-1651. Mail filings must use Form G-1450 (card from a U.S. bank) or Form G-1650 (U.S. bank ACH), with a separate payment form for each benefit request.
6. Step 6: Submit Form I-129 online or by mail to the correct USCIS filing location before the Form I-94 expires, and save the Form I-797C Receipt Notice.

What happens if an H-1B extension is filed late

In general, USCIS does not approve an extension of stay if your status expired before the petition was filed. Under the USCIS Policy Manual, officers may use their discretion to excuse a late filing if the delay was due to extraordinary circumstances beyond the person's control, the length of the delay was reasonable, the person did not otherwise violate status, the person remains a bona fide nonimmigrant, and the person is not in removal or deportation proceedings.

Examples of extraordinary circumstances include remaining in the United States due to a strike, lockout, or labor dispute, an inability to get a certified LCA from the Department of Labor because of a lapse in government funding, or losing status because an employer retaliated against the worker for reporting an LCA violation.

If USCIS excuses the late filing and approves the extension, the approval is backdated to the expiration date of your prior H-1B admission period. If USCIS denies an extension request (whether filed on time or late), you are considered out of valid status as of your I-94 expiration date. If your employment ended, read our guide to the H-1B 60-day grace period.

The 240-day rule: working while your extension is pending

When your current H-1B status expires while a timely filed, non-frivolous extension petition is pending at USCIS, you enter a period of authorized stay. If that petition requests an extension of the same employment for the same employer, you are authorized to keep working for up to 240 days after your Form I-94 expires, or until USCIS makes a decision, whichever comes first.

Rules differ if you are changing jobs or terms. Under H-1B portability, if a petition requests a change in employment or a new H-1B employer, you are authorized to work in the new employment for the entire time the petition is pending at USCIS, not just 240 days. In either case, if USCIS denies the petition, your work authorization ends automatically when USCIS notifies your employer of the denial.

Worked example of the 240-day timeline: Suppose your Form I-94 expires on June 30, 2027, and your current employer submits Form I-129 to extend the same role on May 10, 2027 (51 days before expiration, meeting the 45-day USCIS recommendation). Starting July 1, 2027, your 240-day work authorization clock begins. By our calculation from the 240-day rule in the USCIS M-274 Handbook for Employers, 240 calendar days from June 30, 2027 runs through February 25, 2028. If USCIS has not decided the petition by February 25, 2028, your authorization to work stops on that date unless the petition is approved.

According to the USCIS Handbook for Employers (M-274), when your current work authorization expires, your employer writes "240-Day Ext." and the date Form I-129 was submitted to USCIS in the Additional Information field in Section 2 of your Form I-9.

• Before the Form I-797C Receipt Notice arrives: Employer keeps a copy of the new Form I-129, proof of fee payment, and proof of mailing with your existing Form I-9.
• Once the Form I-797C Receipt Notice arrives: Employer keeps the I-797C with your Form I-9 in place of the petition copy, payment proof, and mailing receipt.
• When the Form I-797 Approval Notice arrives (or at day 240, whichever comes first): Employer must reverify your employment authorization using Supplement B of Form I-9 and must give you the attached Form I-94.

H-1B extension processing time and premium processing

Your employer can file Form I-907, Request for Premium Processing Service, either together with Form I-129 or as an upgrade while Form I-129 is pending. For Form I-129 H-1B petitions, USCIS guarantees adjudicative action within 15 business days, or it refunds the premium processing fee.

The 15-business-day clock starts when USCIS receives a properly completed Form I-907 with a valid signature and correct fee at the proper filing address. Within those 15 business days, USCIS will issue an approval notice, a denial notice, a Notice of Intent to Deny (NOID), or a Request for Evidence (RFE), or open an investigation for fraud or misrepresentation. If USCIS issues an RFE or NOID, the 15-business-day clock stops and resets, and a new 15-business-day period begins once USCIS receives the response.

Only the petitioning employer or their attorney or accredited representative (with a Form G-28) may sign and file Form I-907. As the H-1B beneficiary, you cannot sign or file Form I-907 yourself (unless self-petitioning), though USCIS allows the beneficiary, petitioner, attorney, or representative to pay the premium processing fee.

Premium processing is not available for Form I-539 applications filed by H-4 dependents. However, if your dependent's Form I-539 (and Form I-765 for an H-4 EAD) is properly packaged and filed at the same time and location as your Form I-129, the officer will review the dependent's application as soon as possible after reviewing your Form I-129.

Extending H-1B beyond 6 years (AC21 rules and recapture time)

USCIS regulations provide four ways to keep or extend H-1B status past the 6th year, and you do not have to currently hold H-1B status when requesting an extension beyond year 6 as long as you previously held H-1B status.

1. Three-year increments with an approved Form I-140 (8 CFR 214.2(h)(13)(iii)(E)): If you have an approved EB-1, EB-2, or EB-3 Form I-140 and an immigrant visa number is unavailable in the U.S. Department of State Visa Bulletin as of the H-1B filing date, USCIS may grant extensions in up to 3-year increments. If your employer withdraws your Form I-140 within 180 days of approval, USCIS automatically revokes the I-140 and you need a new basis to extend past 6 years (though you keep your priority date). Once your Form I-140 has been approved for at least 180 days, an employer's withdrawal or business termination alone will not cause USCIS to revoke the I-140, and you can continue using it to extend H-1B status in 3-year increments with any H-1B employer.

2. One-year increments for lengthy adjudications (8 CFR 214.2(h)(13)(iii)(D)): If at least 365 days have passed since a permanent labor certification (PERM) or an employment-based immigrant visa petition (such as Form I-140) was filed on your behalf, USCIS may grant H-1B extensions in up to 1-year increments. You lose eligibility for 1-year extensions if you fail to file Form I-485 or apply for an immigrant visa within 1 year of an immigrant visa becoming available, unless visa retrogression interrupts that 1-year window (giving you a fresh 1-year window when a visa becomes available again) or USCIS excuses the delay due to circumstances beyond your control, including a voluntary or involuntary job change.

3. Recapturing time spent outside the United States: Any trip outside the United States lasting more than 24 hours does not count toward the 6-year maximum and can be recaptured. Your employer must submit a chart of your dates outside the country backed by passport stamps, CBP Form I-94 travel history, airline tickets, and boarding passes.

4. Seasonal or intermittent employment exception: The 6-year limit does not apply if you do not reside continually in the United States and your U.S. employment is seasonal, intermittent, or for a total of 6 months or less per year, backed by arrival and departure records, tax returns, and records of employment abroad.

• H-4 dependent extensions past 6 years: Your H-4 spouse and unmarried children under 21 may extend their H-4 status for the same duration as your post-6th-year H-1B.
• H-4 spouse EAD: Your H-4 spouse can apply for an EAD on Form I-765 if you have an approved Form I-140, or if you have been granted an H-1B extension beyond 6 years under the 365-day pending PERM or I-140 rule.
• H-4 time does not count against an H-1B clock: A spouse who spent 6 years on H-4 can still qualify for their own 6-year period of H-1B status.

International travel, the $100,000 proclamation, and visa stamping

You must be physically inside the United States when your employer files an H-1B extension of stay petition. Once it is filed, departing the United States while an extension of stay is pending will generally not cause USCIS to deny the extension request (unlike a pending change of status, which is considered abandoned if you leave).

Under the September 19, 2025 Presidential Proclamation (Restriction on Entry of Certain Nonimmigrant Workers), petitions filed at or after 12:01 a.m. Eastern on September 21, 2025 for beneficiaries outside the United States without a valid H-1B visa, or petitions requesting consular notification, port of entry notification, or pre-flight inspection, or cases where USCIS finds the worker ineligible for an extension of stay, are subject to an additional $100,000 payment rule. However, the Proclamation does not apply to an extension of stay petition granted for a worker inside the United States, or when that worker later travels abroad to apply for a visa stamp based on the approved petition. (On June 8, 2026, the U.S. District Court for the District of Massachusetts vacated agency guidance implementing the $100,000 payment requirement in State of California v. Mullin, and on July 24, 2026, the First Circuit denied the government's motion for a stay, so DHS is complying with the court's order while it considers next steps.)

An approved Form I-129 (Form I-797, Notice of Action) extends your status inside the United States, but it is not a visa. If you travel outside the United States after your H-1B visa stamp expires, you must apply for a new H-1B visa stamp at a U.S. Embassy or Consulate abroad before re-entering, and present a valid passport, valid H-1B visa (if required), and Form I-797 approval notice to U.S. Customs and Border Protection. Read our guide to H-1B visa stamping.

What the consular officer may ask at stamping after an extension

When you apply for a new visa stamp after an H-1B extension, the officer checks that your current duties, salary, and worksite still match the Form I-129 and Labor Condition Application your employer filed. Use our guide to H-1B visa interview questions to prepare, and have the facts and documents below ready.

• "Are you still working for the same employer in the same role?" What it checks: Whether your case is a continuation or involves changed duties or a new employer. How to prepare: Know your exact job title, tenure with the petitioner, and whether any terms changed on the new Form I-129.
• "What is your current salary, and where do you work?" What it checks: That your pay and physical worksite match the certified LCA (Form ETA-9035/9035E). How to prepare: Know the base salary and exact city and state on your Form I-129 and LCA, and carry recent pay stubs and W-2 forms.
• "How many years have you been in H-1B status, and how are you extending past six years?" What it checks: Eligibility under the 6-year cap or AC21 rules. How to prepare: Know your initial H-1B start date and whether your extension uses recaptured days abroad or an approved Form I-140 / pending PERM, and carry your Form I-140 approval notice if past year 6.
• "Did you ever fall out of status or have a gap between petitions?" What it checks: Whether your extension was timely filed before your prior Form I-94 expired. How to prepare: Know your previous Form I-94 expiration date and the receipt date on your new Form I-797, and carry both notices.
