17-Month STEM Extension

The 17-Month STEM Extension OPT allows some students who have degrees in certain Science, Technology, Engineering, and Math (STEM) fields to apply for an additional 17 months of OPT, giving them a total of 29 months of work authorization.  

To be eligible for the 17-Month STEM Extension, you must:

  • be working for an employer who uses the E-Verify tracking system, and
  • have completed your STEM degree (check the CIP Code on the STEM Designated Degree Programs List and compare with your "primary major" on page 3 of your I-20)

USCIS recommends applying 3 to 4 months prior to the expiration date on the Post-completion OPT EAD. Download the 17-Month STEM Extension Application.  You may email your documents to IPS or mail them via USPS/FedEx.  Please make sure to include a pre-paid self-addressed return envelope. 

Additional student reporting requirements while on the STEM Extension OPT: Submit 17-Month STEM Extension Report Form.

Every 6 months you must submit a validation report to IPS. These reports begin on the date the STEM Extension starts and end when your F-1 status ends, or when the STEM extension ends, whichever is first. The validation report must include:

  • Full legal name
  • SEVIS ID number
  • Current mailing and residential address
  • Name and address of the current employer
  • Date you began working for the current employer

Students pursuing a period of 17-Month Extension OPT MUST:

  • Work/volunteer in a position for an E-Verify employer (paid or unpaid is acceptable)
  • Work only in a position related to your STEM degree
  • Have no more than 120 days of unemployment time during the entire period of Post-completion OPT (regular Post–completion OPT and the 17 Month STEM Extension OPT). This will constitute a violation of your F-1 status.  Go to our Guide to Unemployment (pdf) for additional information.

FAILURE TO COMPLY WITH ANY OF THE ABOVE REQUIREMENTS CONSTITUTES A VIOLATION OF YOUR LEGAL F-1 STATUS.
