STEM Extension

Students who hold degrees in Science, Technology, Engineering, and Mathematics (STEM) may be eligible to apply for an additional 24 months of Optional Practical Training (OPT), for a total of 36 months of OPT.  Please check the STEM Designated Degree Program List to determine if you are eligible to apply for an extension.  You must also be working for an E-Verify employer.

An OPT STEM extension application MUST be received by USCIS before your current OPT ends.  It is recommended that you mail your application to USCIS 90 days prior to your OPT end date.

It might be possible to apply for a STEM extension based on a prior U.S. degree.  The prior degree must have been issued in within the past 10 years from an accredited and SEVP-certified school.  Please contact OISS to find out if you are eligible.
