Extension Option for STEM Field Majors

STEP ONE: Confirm Eligibility

F-1 students whose OPT is based on a Bachelor's, Master's, or Ph.D. degree in Science, Technology, Engineering, or Mathematics (STEM) field, as defined by DHS, may be eligible for a one-time, 17-month extension of OPT. Click here for a current list of STEM-eligible IU majors. Updates will be made available as they develop.

In order to be eligible for this extension, students applying for this benefit must:

  1. Already be on post completion OPT based on a STEM-eligible degree.
  2. Be employed by, or have a job offer from, an employer who is registered with the E-Verify employment verification system. E-Verify is an internet-based system operated by the Department of Homeland Security in partnership with the Social Security Administration. For more information on E-Verify, visit this page.
  3. Have fewer than 90 days of unemployment while on OPT.
  4. Hold an appropriate degree in one of the DHS-approved STEM fields.
  5. Not have previously been approved for a 17-month extension of OPT.
  6. Submit the OPT application to USCIS prior to the expiration of the current post-completion OPT (USCIS must receive the application before the expiration date on the current EAD).

Applying For OPT STEM Extension Requests

F-1 students who are currently authorized for OPT based on completion of a Bachelor's, Master's or Ph.D. degree in a Science, Technology, Engineering or Math (STEM) field, as defined by DHS, may be eligible for a one-time only 17-month extension of OPT.

Students may apply for a STEM extension up to 120 days prior to the end date listed on their EAD Card. Due to processing and mailing times, it is wise to submit this extension request at least forty-five (45) days prior to the current OPT end date.

Students who file a timely application for an extension will be able to continue employment while the extension application is pending with USCIS, until it is approved or denied, or for 180 days, whichever comes first.

      2. New I-20 with DSO authorization for the OPT STEM extension

      Please note: If you send incomplete or inaccurate documents, the OISS will contact you for corrections and request that you resend corrected copies.  Incomplete or inaccurate documents will delay the processing of your application. It may take up to two weeks before we are able to process your packet.
