You must have completed at least one academic year with the same SEVIS number (found at the top left side of page 1 of the I-20).
You must apply prior to the end of the 60 day grace period following the quarter/term in which all requirements for graduation are met (for graduate students this means all degree requirements except dissertation/thesis/project).
Students in F-1 status who are currently on OPT can extend their work authorization an additional 24-months total if they meet certain criteria. Students who extend are required to maintain their F-1 status under STEM OPT Extension regulations. Official Department of Homeland Security guidance on the STEM OPT Extension regulations can be used as a resource if needed.
Optional Practical Training (OPT) gives an F-1 student the opportunity to apply what they have learned in a degree program through off-campus employment after completion of all degree requirements.
Employment approval can take several weeks to 90 days or more, so careful planning is required. We recommend submitting your OPT request in the earliest timeframe possible according the OPT Timelines below.”
