The 240-Day Rule: Working While Your H-1B Extension Pends

Your H-1B extension has been filed. Your current I-94 expiration date is circled on the calendar. And your recruiter or manager is asking, gently, whether you can still bill next week. This is one of the most common panic moments in a consulting career, and it has a specific regulatory answer.

The rule you want is 8 CFR 274a.12(b)(20). It is narrow, mechanical, and frequently confused with a completely different rule that covers changing employers. Getting the two mixed up is the single most common mistake consultants and their managers make during a pending extension.

This article walks through what the regulation actually authorizes, who qualifies, what happens if adjudication runs long, and where consultants trip themselves up.

What 8 CFR 274a.12(b)(20) Actually Authorizes

The regulation provides an automatic extension of employment authorization, for up to 240 days, when three conditions are met:

• You are currently in a nonimmigrant classification covered by the rule (H-1B is one of them).
• Your employer filed a timely petition to extend your status before your current authorized period (the date on your I-94) expired.
• The extension petition requests the same classification, with the same employer, without a material change in your employment.

If all three are true, you may keep working past your I-94 expiration date, without a gap, for up to 240 days or until USCIS decides the petition, whichever comes first.

Who Is Covered

8 CFR 274a.12(b)(20) is not H-1B-specific. It covers a list of nonimmigrant categories, including H-1B, H-1B1, H-2A, H-2B, H-3, L-1, O-1, P, TN, E-1, E-2, E-3, R-1 and CW-1, among others. For consultants working under H-1B, TN, or E-3, the mechanics are the same.

What Happens on Day 241

If your petition is still pending on day 241, your employment authorization under this rule ends automatically. There is no grace extension beyond 240 days written into the regulation. At that point:

• The employer must stop assigning you work and stop paying wages, because there is no legal basis to continue employing you.
• You are not in unlawful presence solely because of this, but you are no longer authorized to work.
• If the petition is later approved, your authorized status and work authorization resume, generally retroactive to the point your prior status ended, per the approval notice.

In practice, this scenario is rare. Most H-1B extensions are adjudicated well inside 240 days, and employers routinely file with Form I-907 premium processing (currently a 15-calendar-day adjudication commitment; confirm the current fee on uscis.gov, since it changes periodically) specifically to avoid getting anywhere near the 240-day ceiling.

The Mistake Almost Everyone Makes: 240-Day Rule vs. H-1B Portability

Here is where confusion causes real problems. The 240-day rule under 8 CFR 274a.12(b)(20) applies only when the same employer is extending you in the same role. It has nothing to do with starting a new job.

Moving to a new employer, or a new consulting engagement under a different sponsoring entity, is governed by a separate provision: H-1B portability under INA 214(n) (added by AC21 section 105). Under portability:

• A new employer files an H-1B petition (change of employer or extension) on your behalf.
• You may begin working for that new employer as soon as the petition is properly filed and receipted, evidenced by the Form I-797 receipt notice, without waiting for approval.
• This authorization is not capped at 240 days. You may continue working for the new employer for as long as that petition remains pending, provided you were previously admitted, previously maintained H-1B status, and the new petition was filed before any period of unauthorized presence.

So the two rules solve two different problems. If you are staying with your current employer and your extension is delayed, 240-day rule. If you are moving to a new employer or a new consulting placement, portability, no 240-day ceiling. Consultants who assume the 240-day clock applies to a new-employer H-1B transfer sometimes stop working unnecessarily, or worse, keep working past 240 days when portability actually never had that limit to begin with, and then misreport the wrong rule to a client's compliance team.

What the Employer Must Do During the Pending Window

The regulation authorizes continued employment; it does not relax the employer's other obligations. While you work under the 240-day extension:

1. The employer must continue paying at least the required wage stated on the underlying Labor Condition Application (Form ETA-9035), just as before the extension was filed.
2. The employer must keep and, if requested, produce evidence of timely filing, typically the Form I-797 receipt notice, for Form I-9 purposes.
3. If premium processing is used to accelerate adjudication, the employer bears that cost as part of the petition filing, not the consultant.
4. If the petition is denied, the employer must stop employing you as of the denial date, not day 240.

Practical Checklist Before You Rely on This Rule

• Confirm the extension petition was filed with USCIS before your I-94 expiration date, not just signed or mailed.
• Confirm it is the same employer, same job classification, filed as an extension of status, not a new employer transfer.
• Get a copy of the Form I-797 receipt notice and keep it accessible for I-9 or client-side compliance checks.
• Track the 240-day date on your own calendar independent of your employer's HR system.
• Avoid international travel on the pending petition unless your attorney has confirmed the specifics; the 240-day work extension does not extend visa validity for re-entry.
• If you are changing employers instead of extending with the current one, ask specifically about portability, not the 240-day rule.
