STEM Extension

Science, Technology, Engineering and Math.

Optional Practical Training (OPT) can be extended for STEM majors for an additional 24 months after the initial 12 month OPT for a total of 36 months.  The applicant must be in a currently approved 12-month OPT period.


  • STEM extension is usually based on the student’s major, not the student’s degree concentration

  • May be based on a STEM degree earned at a prior university.

  • Be in a current period of initial, approved, post-completion OPT (1st 12 month approval)

  • Have current employment or an offer of employment from an employer participating in the E-Verify program.

  • Have a degree with an eligible STEM CIP code.

  • To determine your CIP code, look on your I-20 for the 6-digit numerical code listed directly beside your major

Application Timeline

Students must apply for the STEM extension before the expiration date listed on their current EAD card (Employment Authorization Document) issued by USCIS. USCIS recommends that students apply 90-120 days prior to their EAD expiration date. the SEVIS Compliance Office recommends eligible students apply no later than one month prior to the EAD expiration date, to allow time for formal receipt processing at USCIS.


The SEVIS Compliance Office strongly recommends you make copies of all documents you send USCIS for your records.

Dates of Approval

Upon approval by USCIS, the STEM extension period will begin the day after the expiration of the first OPT period (as listed on the EAD card), and will end 24 months after that. For example, if the current EAD expires on October 1, the STEM period will begin on October 2 of the same year.

Working BEFORE STEM Approval

If your current EAD has expired and a STEM extension is pending with USCIS, you may continue to work for up to 180 days while the extension is pending. Upon approval, USCIS will issue and mail you a new EAD card showing the extended dates.
