F-1 24-Month STEM Optional Practical Training (STEM OPT) Extension

What is the STEM OPT Extension?

Recipients of a Bachelor’s, Master’s, or Doctoral degree in a field listed among the U.S. Department of Homeland Security (DHS) STEM-Designated Degree Program List, and who are currently authorized for post-completion F-1 Optional Practical Training (OPT) may be eligible to apply for a 24-month STEM OPT Extension. Students may be eligible for a maximum of two periods based on different STEM degrees in their lifetime following the completion of eligible degrees.

The STEM-Designated Degree Program List is organized based on U.S. Department of Education CIP Codes and can be found at the Study in the States website.

  • CIP Codes at MIT are assigned to each academic program based on the MIT program curriculum and is determined in coordination with departments and the Office of the Provost, Insitutional Research
  • The CIP code is used to determine eligibility for a 24-month STEM OPT Extension
  • Please check your CIP Code on page 1 of your Form I-20 (under ‘Program of Study’ in the middle of the page) against the DHS STEM-Designated Degree Program List to confirm that your program is a STEM-designated degree program

For more information, Study in the States has launched the STEM OPT Hub.

Application Deadlines

The USCIS Processing Center must receive the complete STEM OPT Extension application and all required documents before your current OPT authorization/EAD card expires. Failure to comply with this deadline will result in loss of the entire STEM OPT Extension benefit.

  • The ISO recommends that you begin preparing the STEM OPT Extension documents and request for a new I-20 from the ISO approximately 100-120 days prior to the expiration of your EAD card.
  • You may submit your application for STEM OPT Extension to USCIS no earlier than 90 days prior to the expiration date of your current OPT authorization/EAD card.
  • The 24-month STEM OPT Extension begins on the day after the approved OPT end date printed on your current Employment Authorization (EAD) card.
  • The student’s employment authorization is automatically extended for up to 180 days if the 24-month STEM Extension application remains pending after the current post-completion OPT EAD expires.
    (This allows for continued employment at the STEM OPT employer while the application is pending. However, travel outside the U.S. is not recommended. See below for details.)

USCIS processing times can take as long as 3-4 months. Please apply as soon as possible to ensure that you receive Employment Authorization Document (EAD) on time. The EAD is the offical work permit issued by USCIS that allows you to be hired and work in the U.S.A. during OPT.
