STEM OPT Extension

STEM Extension of F-1 Optional Practical Training (OPT)

The STEM (Science, Technology, Engineering and Math) extension allows students who have completed a degree in an approved STEM field to extend their OPT work authorization for an additional 24 months, for a total of 36 months, and gain further practical experience in their field of study, complementing the academic work. While on a STEM extension you remain in F-1 status and need to comply with F-1 regulations.

Change Employers

While on the STEM OPT, you are permitted to change employers provided the new job is directly related to your academic field of study and commensurate with your level of education, and the employer is enrolled in E-Verify. You need to submit a new I-983 Form to OISSS and update your employer information using the online OISSS form each time you change employers.

Travel While on OPT

Students can travel in and out of the U.S. while on STEM.  If a student travels outside the U.S. he/she must have an approved EAD card to enter, and must re-enter in F-1 status; otherwise the STEM authorization will automatically end


If you travel outside the U.S. while on OPT, you must re-enter in F-1 status; otherwise your OPT authorization will end. Please contact OISSS prior to travel to discuss any possible issues.

Students must present the following to the inspecting officer at the U.S. port of entry:

  • Valid passport

Change of Immigration Status, Permanent Departure of U.S. or Starting New Academic Program During STEM OPT

You MUST inform OISSS as soon as possible of any changes in your status, so that the F-1 record can be appropriately updated.

  • Change of immigration status: If approved for a change of immigration status (i.e. F-1 to H-1B) your F-1 status and OPT will end upon the start date of the new immigration status.  
  • Leave the U.S. permanently:  If you decide to leave the U.S. for longer than 5 months, your post-completion OPT is no longer valid.  
  • Start a new full-time academic program: If you are admitted into a new full-time academic program, your SEVIS record must be updated with the new program’s information or transferred to your new school. Your OPT is officially ended when the SEVIS record is transferred.

Students on the STEM Extension of OPT must submit a final self-evaluation (page 5 of the I-983 Form) when completing their OPT.
