H-1B 240-Day Rule for Pending Extensions: Travel, I-9, and Denials

The H-1B 240-day rule lets you keep working for your current employer for up to 240 days after your Form I-94 expires, as long as that employer filed a Form I-129 extension petition with USCIS before the expiration date. The authorization exists so processing delays don’t force a lawful worker off the job while a timely extension sits in the queue. It has hard edges, though. It only covers continued work with the same employer, the calendar runs whether USCIS acts or not, and a denial ends everything the day it issues.

Who Qualifies

Three conditions have to line up before the rule applies under 8 CFR 274a.12.¹

USCIS must receive the I-129 before the expiration date on the worker’s I-94. One day late and the protection is gone.
The petition must be from the employer who already sponsors the worker. A petition filed by a different employer does not trigger the rule.
The petition must ask to extend the same nonimmigrant classification. A request to change to a different visa category does not activate the 240-day authorization.

The regulation also requires the job duties and terms of employment to stay substantially the same as the original petition, and any conditions attached to the initial authorization carry forward through the 240-day window.¹ The same 240-day framework covers several other categories, including L-1, O-1, TN, E, P, and R-1, but the conditions above are what matter for an H-1B extension.²

How the Clock Runs

Day one is the day after the I-94 expiration date. Every calendar day counts, including weekends and federal holidays. If USCIS approves or denies the petition before the 240 days run out, that decision ends the automatic authorization. If day 241 arrives with no decision, the worker has to stop working even though the petition is still pending.²

A Request for Evidence does not pause the clock. If USCIS issues an RFE on day 100, the days keep ticking while the employer prepares a response. Premium processing has its own 15-business-day timer that resets when the employer submits an RFE response, but the 240-day calendar is separate and has no pause button.³

Work Authorization Ends Before Lawful Stay Does

The 240-day rule is about the right to work, not the right to remain in the country. A separate regulation treats a nonimmigrant with a timely-filed extension as being in an authorized period of stay while the petition is pending, and that authorized stay can continue past day 240. In practical terms, a worker who hits day 241 with no decision has to stop working but is not yet accruing unlawful presence. Unlawful presence starts if USCIS denies the petition, provided the filing was timely and non-frivolous.⁴

What the Employer Does With the I-9

The I-9 file has to reflect the pending extension. Before the receipt notice arrives, the employer keeps copies of the I-129 petition, proof of the filing fee payment, and proof of mailing with the existing I-9.²

Once Form I-797C shows up, it replaces those interim documents. The employer files the receipt notice with the I-9 and writes “240-day Ext.” along with the filing date in the Additional Information box in Section 2.² Recording the receipt number alongside the day-240 date is what gives an employer a defensible audit trail if ICE ever reviews the file. I-9 paperwork penalties are civil fines that adjust annually for inflation and add up quickly across multiple employees.⁵

Travel Is the Big Risk

Leaving the country while relying on the 240-day rule is one of the worst things an H-1B worker can do. Re-entry is the problem. If the visa stamp in the passport has expired, a new one from a U.S. consulate is generally required before returning, and appointments can take weeks or months.

Automatic revalidation for short trips to Canada or Mexico does not fix this. That provision requires a valid, unexpired I-94, and a worker inside the 240-day period has an expired I-94 by definition.⁶ Even with a still-valid visa stamp, departure can be treated as abandoning the pending extension, and Customs and Border Protection may refuse to readmit on the strength of a pending petition alone. The cautious approach is to stay put until USCIS approves the extension and issues a new I-94.

The Rule Does Not Cover Job Changes

The 240-day rule and H-1B portability get mixed up often, and the mistake is expensive. Portability is what lets an H-1B worker begin a new job as soon as the new employer files a non-frivolous I-129, so long as it is filed before the current authorized stay expires.⁷ The new employer also has to submit a certified Labor Condition Application covering the new work.⁸

The 240-day rule covers only continued work with the current employer during a pending extension. If the job is changing, the legal basis for continuing to work is portability. Citing the wrong rule when the facts don’t fit it can turn otherwise lawful work into an unauthorized employment problem.

Premium Processing Avoids the Question

Employers who want a decision before the I-94 runs out can file Form I-907 for premium processing. USCIS commits to acting within 15 business days, which can mean approval, denial, or an RFE, but at least a status change before the extension deadline if the request is submitted early enough.³

The premium processing fee for H-1B petitions is $2,965 as of March 1, 2026, on top of the regular filing fees.⁹ An RFE resets the 15-business-day clock when the employer responds, so a complex case can still take longer than expected. Even with that caveat, premium processing sharply reduces the chance of ever needing the 240-day rule as a fallback.³

How the Authorization Ends

Whichever of these happens first is the end of the 240-day work authorization:

USCIS approves the extension. The new authorized stay takes over with no gap.
USCIS denies the extension. Employment authorization ends immediately on notification.¹
The employer withdraws the petition. Authorization ends when the petition is no longer pending.
Day 241 arrives with no decision. The worker has to stop working even though USCIS has not acted.

What a Denial Means

A denial ends things quickly. Unlawful presence begins accruing the day after USCIS issues the denial, and there is no automatic wind-down period.⁴ The 60-day grace period some H-1B workers rely on applies after termination of employment, not after a petition denial. More than 180 days of unlawful presence triggers a three-year bar on re-entry, and more than a year triggers a ten-year bar. A worker who receives a denial inside the 240-day window should get to an immigration attorney immediately about a motion to reopen, a fresh petition, or departure planning.

Working past any of these termination points is unauthorized employment. It can lead to removal proceedings and inadmissibility for future visa applications, and it exposes the employer to its own penalties. Both sides need to know the day-240 date and act the moment a denial arrives.

H-4 Dependents Are Not Covered

The 240-day rule does not extend to H-4 spouses. USCIS lists the categories eligible for the 240-day employment authorization, and H-4 is not one of them.² An H-4 spouse’s right to work depends on an approved EAD, and after October 30, 2025, DHS ended the automatic extension of EADs for renewal applicants in most categories.¹⁰ An H-4 spouse whose EAD lapses cannot work until USCIS approves the renewal, even while the principal H-1B worker keeps working under the 240-day rule.¹¹ Filing the H-4 EAD renewal as early as the rules allow, up to 180 days before expiration, is the practical response.
