Cap-Gap Extension Calculator
Determine your automatic F-1 status and OPT employment authorization extension dates when transitioning from OPT to H-1B. Enter your OPT end date and H-1B petition details to see your cap-gap coverage period, what you can and cannot do during this time, and critical travel warnings.
How This Tool Works
Enter your OPT or STEM OPT end date, confirm that you were selected in the H-1B lottery, and provide your H-1B petition filing status. The tool calculates your cap-gap coverage period, which runs from your OPT end date through September 30 of the fiscal year your H-1B is set to begin. If your H-1B petition has been denied or withdrawn, the tool shows that your cap-gap protection has ended and outlines your next steps.
What the Data Covers
Cap-gap is defined by 8 CFR 214.2(f)(5)(vi), which provides for the automatic extension of F-1 status and any OPT employment authorization for students who are the beneficiaries of H-1B petitions filed for October 1 start dates. The extension covers the period from the OPT end date through September 30 of that year. This tool applies those regulatory rules to your specific dates. It does not account for edge cases such as change-of-employer petitions or concurrent H-1B filings.

Data Source & Methodology
Cap-gap rules are defined in 8 CFR 214.2(f)(5)(vi) and apply to F-1 students whose employers file H-1B cap-subject petitions requesting an October 1 start date. The tool calculates the extension period based on the regulatory framework: coverage runs from the OPT or STEM OPT end date through September 30 of the applicable fiscal year. Denied or withdrawn petitions terminate cap-gap immediately. This tool does not replace advice from your DSO or immigration attorney.
Cap-gap has important limitations. International travel during cap-gap is extremely risky and may result in being unable to re-enter the United States. Employment is limited to the employer listed on your EAD. If your H-1B petition is denied, withdrawn, or revoked, cap-gap ends immediately. Edge cases such as employer changes, multiple H-1B filings, or cap-exempt petitions may affect your coverage. Always verify your specific situation with your DSO and a licensed US immigration attorney.
