H-1B Extension Status: Can You Keep Working While It's Pending?

Your H-1B extension is pending and your I-94 is about to expire. Here's the federal rule that decides whether you can keep showing up to work.

Your current H-1B is running out. Your employer filed the extension weeks ago. USCIS shows a receipt number and nothing else. And your I-94 expiration date is circled in red on your calendar, closer every day. The question you actually need answered isn't abstract immigration theory — it's whether you can walk into work tomorrow.

For most people in this exact situation, the answer is yes, and the reason has a name: the 240-day rule. It's a federal regulation, not a policy that shifts with each administration, and understanding exactly how it works — and where it doesn't apply — is the difference between confident planning and guessing.

The short answer: the 240-day rule

Under 8 CFR 274a.12(b)(20), an H-1B worker's employment authorization continues automatically for up to 240 days past the expiration date on Form I-94, or until USCIS decides the extension, whichever comes first — provided three conditions hold:

1. Your employer filed the extension request (Form I-129) before the expiration date printed on your current I-94. This is what "timely filed" means — there's no grace window for a late filing.
2. The request is for a continuation of the same underlying employment: same employer, same H-1B classification, no material change to the job.
3. The petition remains pending with USCIS. The moment it's decided, the 240-day authorization ends and your actual status (approved, denied, or an RFE outcome) takes over.

If those three are true, you keep working on the strength of the pending case itself — you don't need an approval notice in hand, and you don't need to carry any special document beyond your expired I-94 and your employer's proof of a timely filing (the I-797C receipt notice, which typically arrives within a couple of weeks of filing).

This is a different mechanism from the AC21 §105 portability rule that lets a new employer's transfer petition let you start immediately on receipt. That rule covers switching employers; the 240-day rule covers staying with the same employer through a renewal. If you're actually changing companies, see our H-1B transfer playbook instead — the mechanics and the risk profile are genuinely different.

Why "timely filed" is the entire ballgame

The 240-day rule has no partial credit. If your I-94 expires on a Tuesday and your employer's attorney files the I-129 on Wednesday, the rule simply does not apply to you — not for one day, not for 239 days. You would be out of status from the moment the I-94 lapsed, regardless of how close the filing was.

This is why HR and immigration counsel push so hard to file H-1B extensions well before the expiration date, typically several months out. If you're the one tracking your own timeline, don't rely on your employer's assurance that "it's being handled" — ask directly for the filing date and, once it's submitted, the receipt number on the I-797C. That receipt notice is your proof the clock started on time. Our guide on reading a USCIS receipt notice walks through what each field and status code actually means.

Checking your actual case status

Once the petition is filed, you have two ways to track it:

• USCIS Case Status Online, using the 13-character receipt number from your I-797C
• Your USCIS online account, which you can link to the case for more detailed status history and any Requests for Evidence (RFEs) as they're issued

Status messages are terse by design ("Case Was Received," "Case Is Being Actively Reviewed," "Response To USCIS' Request For Evidence Was Received") and don't tell you a decision date. If your case shows no movement for months, that alone isn't a red flag — see our receipt notice guide for how to interpret a stalled-looking status versus one that actually needs action from you.

Standard vs. premium processing

You can pay to put a hard clock on the decision instead of waiting on standard processing.

Premium processing doesn't change whether the 240-day rule applies to you — it only compresses the uncertainty. If you filed on time and are already working under the 240-day rule, premium processing mainly buys you an earlier definitive answer rather than extended eligibility to work; the 240-day allowance already covers you well past that window in a typical case. For a deeper walkthrough of when premium processing is worth the fee, see our H-1B premium processing guide.

Extending past the six-year H-1B limit

Not every "extension" is a routine same-terms renewal inside the normal 6-year H-1B period. If you're approaching year six, you're likely extending under one of two different statutory provisions from the American Competitiveness in the Twenty-First Century Act (AC21):

The 240-day rule applies the same way to all of these as long as the extension was filed before your I-94 expired and doesn't change your employer or role — the statutory basis for how long the underlying H-1B can run doesn't change whether you can keep working while the paperwork is pending.

If your extension beyond year six depends on where your green card case sits, your priority date matters. As of the August 2026 Visa Bulletin, EB-2 India is unavailable for the remainder of FY2026 and EB-2 China is frozen at September 1, 2021; EB-3 dates sit before January 1, 2014 for India and before January 1, 2022 for China. The Department of State has projected EB-2 India could move to around July 2014 or earlier once FY2027 opens on October 1, 2026 — but that's a forecast, not a commitment, and bulletin cutoffs move monthly. Check the current month's bulletin yourself before planning around any date. AC21 portability also affects whether you can change jobs mid-green-card-process without restarting the clock — our guide on AC21 portability and green card job changes covers that separately.

What if the extension involves any change at all

The 240-day rule is unforgiving about "same employer, same terms." If your extension is bundled with a promotion, a new job title, a different worksite outside your existing LCA's metro area, or any other material change, USCIS may treat it as requiring an amendment rather than a clean extension — which affects how the pending-case work authorization analysis applies. This is a genuinely fact-specific question, and getting it wrong can mean working without authorization without realizing it. Our post on H-1B amendments and working while one is pending goes into how amendments differ from straight extensions. If your situation involves any change beyond a like-for-like renewal, that's a conversation for an immigration attorney before you assume the 240-day rule covers you.

About the $100,000 fee

If you've seen headlines about a $100,000 H-1B fee and are worried it applies to your extension: it doesn't, and as of August 2026 it isn't being collected from anyone. The fee was vacated by a federal district court on June 8, 2026, which held it exceeded executive authority and violated the Administrative Procedure Act. The government appealed, and the First Circuit denied the government's request to reinstate it on July 24, 2026. The underlying proclamation's 12-month restriction is set to sunset on September 20, 2026 unless extended. None of this affects the cost or timeline of a standard extension filing — but the litigation isn't fully resolved, so if this is relevant to your situation, confirm the current posture with your employer's immigration counsel rather than relying on a headline.

Traveling while your extension is pending

Leaving the country while an extension is pending adds real complexity, and it's worth naming plainly rather than glossing over. The Department of State ended interview waiver eligibility for H-1B applicants on October 1, 2025 — every H-1B stamping appointment, including a routine same-employer renewal, now requires an in-person consular interview, generally in your country of nationality or usual residence. If your existing visa stamp is still valid and unexpired, you may be able to travel and re-enter on it while your extension is pending, but if it's expired, you'll need a new interview-based stamp before you can return — and that timeline is entirely outside your control or USCIS's. Our guide on travel considerations while a petition is pending covers this in more depth. If travel is unavoidable, talk to your immigration attorney before booking anything.

Common mistakes

• Assuming the 240-day rule applies without checking the filing date. If the extension was filed even one day after the I-94 expired, it doesn't apply — full stop.
• Treating premium processing as a guarantee of approval. It only guarantees a timeline for a decision, which can be an RFE or a denial just as easily as an approval.
• Assuming a case with no status updates means something is wrong. Long stretches of "Case Is Being Actively Reviewed" are normal; check the USCIS processing times page for your service center rather than assuming a stalled case.
• Continuing to work past a denial notice. The 240-day allowance ends the instant USCIS decides the case — not at the 240-day mark, and not when you eventually receive the paper notice in the mail.
• Booking international travel without confirming stamp validity and interview requirements first. With the interview waiver gone, plan for a real consular appointment, not a dropbox.
• Not distinguishing a clean extension from an amendment. A worksite move or role change bundled into the "extension" can change which rule governs your work authorization while it's pending.

The bottom line

If your H-1B extension was filed by your employer before your I-94 expired, for the same role with the same employer, federal regulation lets you keep working for up to 240 days past that expiration date or until USCIS decides your case. That's the mechanism, not a favor from any individual officer, and it holds regardless of how backlogged a particular service center is. Your actual leverage is in the filing date — get confirmation of when the I-129 was submitted, keep the receipt notice, and track your case status rather than guessing. For anything more complicated than a like-for-like renewal — a promotion, a worksite change, a green card timeline overlapping your 6-year limit — loop in a licensed immigration attorney before you assume you know how the rule applies to you.
