The transition from Optional Practical Training (OPT) to H-1B follows a specific timeline. Most F-1 students on OPT apply for H-1B during the March registration period for an October 1 start date. If selected in the lottery and approved, your status changes from F-1/OPT to H-1B on October 1. The "cap-gap" provision automatically extends your OPT and F-1 status from the normal OPT end date through September 30, bridging any gap.
STEM degree holders are eligible for a 24-month OPT extension (total 36 months of OPT). This provides up to 3 additional chances at the H-1B lottery. STEM OPT requires: a degree in a STEM-designated field, employment with an E-Verify enrolled employer, and a formal training plan (Form I-983). The extended OPT time is valuable — it gives you multiple lottery attempts and allows you to build experience that strengthens future H-1B petitions.
If your employer files a timely H-1B petition on your behalf (change of status from F-1), and your OPT or STEM OPT would expire before October 1, the "cap-gap" rule automatically extends your employment authorization through September 30. This prevents any gap between OPT expiration and H-1B start date. The cap-gap extension applies only if the H-1B petition is filed as a change of status (not consular processing) and is pending or approved.
If not selected, your options include: STEM OPT extension (if eligible and not already used), cap-exempt employment at universities or research organizations, employer transfer to a foreign office and later L-1 visa, O-1 visa for extraordinary ability, entrepreneur visa options, graduate school enrollment to maintain F-1 status, or employment in a country with reciprocal trade agreements (Canada, Australia).
Yes, if you have valid EAD from OPT. The cap-gap provision extends both your F-1 status and employment authorization through September 30 of the fiscal year for which the H-1B was filed.
If the H-1B petition is denied, your cap-gap extension ends and you must stop working. You may have a brief period to depart the U.S. or change status. Consult your DSO immediately.
During OPT, you can change employers with some restrictions (must be related to your field of study). If the new employer files the H-1B, the cap-gap applies to the new petition.
