The H-1B Cap-Gap Extension Explained
- Cap gap begins when USCIS receives a cap-subject H-1B change of status petition—not at registration or lottery selection.
- Cap gap can extend F-1 status, but work authorization continues only if OPT or STEM OPT was still valid at filing.
- If OPT has ended and you are in the grace period, you may receive a status extension but generally cannot keep working.
- Cap gap usually lasts until the H-1B start date, but it can end early if the petition or change of status is rejected or denied.
The H-1B cap gap is a bridge between the end of a student’s F-1 status or OPT work authorization and the beginning of their H-1B status. Because cap-subject H-1B petitions must be submitted at least six months before the H-1B worker can start work, it’s possible for their F-1 status to expire in the meantime. H-1B cap-gap rules allow the worker to remain in status until their H-1B role begins.
What is the H-1B cap gap?
The term cap gap refers to the time between when the Optional Practical Training (OPT) for an F-1 student visa expires and when an H-1B job begins.

What does the H-1B cap gap do?
The cap-gap rules automatically extend an eligible student’s duration of status—and sometimes their work authorization—when a cap-subject H-1B petition requesting a change of status is filed on their behalf.
Since many F-1 students graduate in the spring or summer, but jobs that require a new H-1B visa cannot start until at least October, there can be a gap of a few months between when F-1 or OPT status expires and when H-1B status starts. The cap gap allows students to bridge that period without losing valid visa status and without having to leave the U.S.

Who qualifies for the H-1B cap gap?
To be eligible for the H-1B cap gap, you must meet the following criteria:
- You are in valid F-1 status when the H-1B petition is filed. This can be during your academic program, OPT, STEM OPT, or during the 60-day grace period.
- You are the beneficiary of a cap-subject H-1B petition that is filed within the H-1B filing period based on a lottery-selected registration for the upcoming fiscal year.
- You are in the U.S. and the petition request is a change of status (not consular processing).
Who doesn’t qualify for the cap gap?
Individuals accepted for cap-exempt H-1B jobs are not eligible for the cap-gap extension because it is not needed. They can start working as soon as their H-1B is approved.
Also, if a beneficiary is outside the U.S. when the H-1B petition is filed, and the petition must go through consular processing, they are not eligible for cap gap.

The 2 types of cap gap
An H-1B cap gap can be either a basic extension of a student’s F-1 duration of status or an extension that includes work authorization. Here are the differences and when each comes into play.
Extension of status
If your OPT has ended and you’re in the 60-day F-1 grace period when your employer files your H-1B petition, your F-1 duration of status is extended, but your work authorization is not.
Work authorization
The H-1B cap gap only extends your work authorization if you still have a valid work authorization at the time your employer files your H-1B petition.
If your OPT or STEM OPT is valid when the H-1B petition is filed, your H-1B cap gap includes authorization to work during the cap gap.
If your OPT or STEM OPT has expired by the time the H-1B petition is filed, you’re not authorized to work during the H-1B cap gap.
| ⚠️ Cap-gap protections generally begin once a cap-subject H-1B petition requesting a change of status is properly filed and USCIS issues a receipt for the filing. The cap gap does not begin at the lottery registration or selection stages. |
How long does the cap-gap extension last?
A cap-gap extension generally runs until your H-1B start date, or until April 1 of the following fiscal year, whichever comes first. If your H-1B start date is October 1, the cap gap typically covers you through September 30.
An extension of status can end if the H-1B petition is denied, withdrawn, revoked, or rejected. In some cases, an H-1B petition can be approved, but a change of status request is denied. In those instances, the H-1B petition is sent to consular processing, and a cap-gap extension ends.
| 💡 Cap-gap extensions are automatic. They depend on your status when USCIS receives your employer’s H-1B change of status petition. If your OPT or STEM OPT was valid at that time, your work authorization can continue the under cap gap even if SEVIS updates lag. |
How the H-1B cap gap affects your I-20 and SEVIS record
A cap-gap extension is automatic. Once your record in the Student and Exchange Visitor Information System (SEVIS) is updated, your school can issue a new Form I-20 if you need proof of extended work authorization for your employer.
SEVIS is updated when USCIS indicates it has received an H-1B petition for you.
You may request an updated I-20 from your designated school official (DSO) after USCIS has issued a receipt notice for your employer’s H-1B petition.
⚠️ If SEVIS doesn’t reflect your cap-gap extension, your school’s international services office can reach out to the SEVIS Help Desk about updating the data.

H-1B cap gap FAQs
Does the $100,000 fee apply to current H-1B visa holders?
In cap-gap scenarios where the student is in the U.S. and the visa petition is for a change of status, the $100,000 H-1B fee generally wouldn’t apply. However, employers should always confirm fee requirements based on the beneficiary’s location and whether the filing is a consular notification or a change of status.
Do I need to apply for the cap-gap extension?
If you are eligible for a cap-gap extension, you will automatically get it once an H-1B petition is properly filed on your behalf. You don’t need to apply or do anything specific to get it. To check if you received your extension, ask your employer for the USCIS receipt number or receipt notice. Then you can request an updated cap-gap I-20 from your DSO.
What happens if my H-1B is denied or withdrawn during a cap-gap extension?
A cap-gap extension ends if an H-1B petition is denied. Be sure to consult your DSO or legal counsel about the rules of a grace period if a petition is denied.
Can I travel while my cap gap is pending?
Travel while a change of status is pending is risky, though you can generally travel abroad after your H-1B change of status has been approved. If you travel abroad before USCIS approves the change of status, USCIS may consider the change of status request abandoned. If you have an urgent need to travel outside the U.S., it’s safest to consult your DSO and legal counsel.
Even with an approved H-1B petition and lawful status extended with the cap gap, your admission to the U.S. is subject to approval by U.S. Customs and Border Protection (CBP).
Will I need an Employment Authorization Document (EAD)?
The H-1B cap gap doesn’t give you a new EAD. It simply extends work authorization if it was valid at the time an H-1B petition was filed. An updated I-20 will reflect any extension of your work authorization.
