STEM Extension Information

STEM OPT Extension Guidelines


Students who hold degrees in STEM fields (Science, Technology, Engineering, and Mathematics) may be eligible to apply for a 24-month extension of Optional Practical Training (OPT), in addition to their 12-month Post-Completion OPT.

Non-STEM field students do not qualify to apply for the extension. It is possible, however, to use a prior U.S degree to apply for the extension if the degree was in a STEM field and was conferred within the last 10 years.

Please check the Designated STEM Degree Program List to see if your degree qualifies you for a STEM OPT extension. If you are not sure, please contact your ISO Advisor.
