H-1B Cap Gap: Staying in the US After OPT Expires While Waiting for H-1B to Start
Every F-1 student selected in the H-1B lottery faces the same timing problem: OPT ends on a specific date, but H-1B status does not begin until October 1. The gap between these two dates -- typically a few months -- is called the H-1B cap gap. Federal regulations automatically extend your OPT work authorization through September 30 in most cases, but the protection has conditions and limits. This guide explains exactly what cap gap covers, what it does not, and what to do if things go wrong.
Frequently asked questions
What is the H-1B cap gap and do I need to apply for it?
The H-1B cap gap is the automatic extension of your F-1 OPT work authorization from the date your EAD expires through September 30, bridging the gap to your October 1 H-1B start date. You do not need to apply for cap gap -- it is automatic under federal regulations (8 CFR 214.2(f)(5)(vi)) as long as your employer filed a cap-subject H-1B petition on your behalf before your OPT authorization expired. Keep your USCIS I-797C receipt notice, expired EAD card, and I-20 together as your proof of cap gap work authorization. Your HR department may need to update your I-9 using the receipt notice.
Can I travel outside the US during the H-1B cap gap?
Traveling internationally during the H-1B cap gap is strongly advised against. Cap gap work authorization does not apply at ports of entry -- a CBP officer who sees an expired OPT EAD and a pending H-1B petition (not yet approved) may deny your reentry. Additionally, many F-1 students let their F-1 visa stamps expire during OPT, and a new visa stamp requires a consular appointment abroad. If you travel during cap gap without a valid F-1 visa stamp, you may be stranded abroad until your H-1B is approved. Consult your Designated School Official and an immigration attorney before any international travel during this period.
What happens to my cap gap if my employer withdraws the H-1B petition?
If your employer withdraws the H-1B petition -- or if USCIS denies it -- your cap gap protection ends immediately on the withdrawal or denial date. You must stop working on that date. You may have a 60-day F-1 grace period to change status or depart the US, but you cannot use this time for unauthorized employment. Options include: filing for STEM OPT extension if you qualify and have not used it, changing to another status (H-4, F-1 for further study, B-2), or departing and seeking H-1B sponsorship from a different employer for the next fiscal year lottery.
