STEM OPT Extension

The STEM OPT extension is a 24-month extension of post-completion OPT. It is available two times to eligible F-1 students who have completed a STEM degree within the last 10 years from an accredited U.S. institution. The regulations for the 24-month extension, effective May 10, 2016, replace the previous regulations for the 17-month extension of OPT. 

Eligibility Criteria

You must meet the following eligibility requirements to be recommended for the STEM extension:

  • You are in a valid period of post-completion OPT

  • You must have recently completed a degree, or have a prior degree, at the bachelor's level or higher, in a field on Department of Homeland Security's STEM-Designated Program List. If your STEM application is based on a previous degree, it must have been awarded within the past 10 years by an accredited U.S. institution. Your degree did not need to be STEM-designated at the time it was awarded.

  • You are employed in a paid position by an employer registered in E-verify. You must work at least 20 hours per week and the employment must be directly related to your STEM degree. Your initial post-completion OPT employer does not need to be the same as your STEM OPT extension employer.  Because the Form I-983 requires a salary amount and employer official certification, self-employment and volunteering do not qualify for the STEM OPT extension.

  • You have not previously completed 2 STEM extensions.

When can I apply?

You must apply for STEM OPT extension before your current period of post-completion ends.

U.S. Citizenship and Immigration Services (USCIS) can receive your application:

  • No earlier than 90 days before your OPT period ends.

  • No later than the day before your OPT period ends.

Normal processing time for ISS is 10 business days. Please allow additional time to mail your application to USCIS. If you have filed your application with USCIS during this period, your employment authorization is automatically extended up to 180 days. It is your responsibility to find out what documentation your employer requires to verify your extended authorization. You may continue working while your STEM extension is being processed by USCIS. We recommend against traveling outside the U.S. while your application is pending with USCIS (Read Can I reenter if my request for OPT is pending? for more information).

Normal processing time for ISS is 10 business days. Processing time for USCIS is approximately 3 months. For information about how to expedite your application with USCIS, read Chapter 12 – Request to Expedite Applications or Petitions of the USCIS Policy Manual.  ISS will not expedite OPT requests and cannot review letters to USCIS to request expedited processing.

  • Work at least 20 hours per week in paid positions for E-Verify employers in positions related to your STEM degree

    • Every 6 months to validate your SEVIS information, regardless of whether there have been any changes

    • Every 12 months complete and upload page 5 of Form I-983. The self-evaluation must be signed by your supervisor.
