H-1B Cap-Gap Extension Explained: What Happens Between OPT and H-1B
The cap-gap bridges the gap between your OPT expiration and H-1B start date. Here's exactly how it works.
Quick Answer
The H-1B cap-gap automatically extends your F-1 status and OPT work authorization from April 1 through September 30 if your employer files a timely H-1B cap-subject petition. This prevents any gap in your legal status between OPT expiration and H-1B start date.
Key Takeaway
The H-1B cap-gap automatically extends your F-1 status and OPT work authorization from your OPT expiration date until October 1 (the H-1B start date) — but only if your employer files a timely H-1B change-of-status petition and you're selected in the lottery.

What Is the H-1B Cap-Gap?
The cap-gap is a regulation (8 CFR 214.2(f)(5)(vi)) that fills the timing gap between:
Your OPT Expires
e.g., June 15
Cap-Gap Period
Auto-Extended
H-1B Starts
October 1
Without the cap-gap, you'd have to leave the US after your OPT ends and return on October 1 when the H-1B starts. The cap-gap eliminates that disruption.
Cap-Gap Timeline 2026
| Date | Event | Your Status |
|---|---|---|
| March 2026 | H-1B registration opens | File registration with employer |
| Late March | Lottery results announced | Selected or not selected |
| April 1 - June 30 | Employer files H-1B petition | OPT continues normally |
| Your OPT expiry | OPT would normally end | Cap-gap auto-extends status |
| Until Oct 1 | Cap-gap period | Can work; F-1 status extended |
| October 1, 2026 | H-1B start date | Status changes to H-1B |
Can You Work During the Cap-Gap?
Yes — if H-1B petition filed as change of status
If your employer filed an H-1B petition requesting change of status (not consular processing), your EAD work authorization is automatically extended until October 1.
No work auth — if consular processing
If the petition requests consular processing instead of change of status, you get F-1 status extension (can stay in US) but NOT work authorization during the cap-gap.
What If Your H-1B Is Not Selected or Denied?
Not selected in lottery
Cap-gap ends. Your OPT expiration date reverts to the original date (or 60-day grace period if already expired).
H-1B petition denied
Cap-gap ends immediately. You enter the 60-day grace period from the denial date.
H-1B petition withdrawn
Same as denial — cap-gap terminates and grace period begins.

Frequently Asked Questions
What is the H-1B cap-gap?
The cap-gap is an automatic extension of F-1 status and OPT work authorization that bridges the gap between your OPT expiration and the October 1 H-1B start date, available when your employer files a timely H-1B petition with change of status.
Can I travel during the cap-gap?
Travel is risky during the cap-gap. If you leave the US, you may not be able to re-enter on F-1 status. Most immigration attorneys recommend NOT traveling during this period.
Do I need a new EAD card for the cap-gap?
No. Your existing EAD card is automatically extended by regulation. USCIS does not issue a new card, but your I-20 should show the cap-gap extension. Keep your original EAD and the updated I-20 together.
