H-1B Cap Timeline for OPT Students

How H-1B Connects to OPT

The H-1B visa is the most common path from OPT to long-term U.S. employment. However, H-1B visas are subject to an annual numerical cap, which means not everyone who applies will receive one. Understanding the H-1B timeline is essential for OPT students planning their next steps.

Because the H-1B cap season and OPT timelines are closely linked, many students use OPT (and the STEM extension) as a bridge to maintain work authorization while pursuing H-1B sponsorship.

The H-1B Cap Season

Each federal fiscal year, USCIS allocates a limited number of H-1B visas. The annual process follows a predictable schedule.

1. March: USCIS opens the electronic registration period. Employers register beneficiaries and pay the $10 registration fee for each.
2. Late March/April: USCIS conducts the lottery if registrations exceed the cap. Selected registrants are notified.
3. April through June: Employers file full H-1B petitions (Form I-129) for selected registrants.
4. October 1: The new fiscal year begins, and approved H-1B workers may start employment.

Regular Cap vs Advanced Degree Exemption

The H-1B program has two pools with separate numerical limits.

• Regular cap: 65,000 visas per fiscal year, open to all qualifying beneficiaries.
• Advanced degree exemption (master's cap): An additional 20,000 visas reserved for beneficiaries with a U.S. master's degree or higher.
• Beneficiaries with a U.S. master's or higher are first entered in the advanced degree pool. If not selected, they are entered in the regular 65,000 pool, giving them two chances.

The Cap-Gap Extension

The cap-gap provision automatically extends the OPT work authorization and F-1 status for students whose H-1B petition has been selected in the lottery but whose H-1B start date (October 1) has not yet arrived.

• If your OPT expires between April 1 and September 30 and your employer's H-1B petition (or registration) has been selected, your EAD and F-1 status are automatically extended through September 30.
• The extension applies to both the work authorization and the duration of status.
• If the H-1B petition is denied, revoked, or withdrawn, the cap-gap extension terminates immediately.
• No additional application is required. Your DSO updates your I-20 to reflect the cap-gap extension.

Using OPT as a Bridge to H-1B

Most F-1 students who transition to H-1B status use OPT to maintain work authorization during the gap between graduation and H-1B approval. Strategic planning can maximize the number of lottery attempts you receive.

• Standard 12-month OPT gives you one H-1B lottery cycle (the spring after graduation).
• With the 24-month STEM extension, you can participate in up to three H-1B lottery cycles, dramatically increasing your chances of selection.
• Employer sponsorship is required. The employer files the H-1B petition and pays associated fees.
• Begin conversations with your employer about H-1B sponsorship early, ideally months before the March registration window.
