Optional Practical Training STEM Extension

Students who have earned a degree from an accredited and SEVIS approved U.S. Institution, either currently or previously, in a STEM field (Science, Technology, Engineering or Mathematics) may qualify to apply for an extension of their OPT for an additional 24 months.  

Students must be employed by an E-verify company.  There must be an established employer-employee relationship between the employer and the F-1 student.

Students may apply for STEM OPT extension up to 90 days prior and no later than their current OPT expiration date. USCIS must receive your application by your OPT expiration date at the latest.

Students are eligible to continue working up to 180 days after their current OPT end date while waiting for a decision from USCIS as long as they have their I-797C Receipt Notice showing that USCIS has received their application.
