STEM Extension


Recipients of bachelor’s, master’s, and doctoral degrees in certain STEM (Science, Technology, Engineering, Mathematics) fields eligible for a one-time 17-month extension of post-completion OPT (for a total eligibility of up to 29 months).

In addition, to be eligible for STEM OPT your employer must be registered in E-Verify, and agree to report to ISSS when your employment ends or is terminated.  You must agree to make periodic reports to ISSS regarding your employment.  Lastly, employment must be directly related to the major area of study.

ISSS facilitates the STEM OPT application process, but final authorization is processed by USCIS (Immigration). It is the student’s responsibility to ensure that the application is submitted at least three months prior to their current OPT end date.



  • Compile the following STEM OPT documents and submit to your International Student Adviser at least 3 months before your standard OPT end date.
    1. OPT STEM Extension document signed by student and employer.
    2. $380 check or money order payable to U.S. Department of Homeland Security
    3. 2 Passport-style photos
    4. Form I-765 with section 17 completed – List your degree as it is shown on your I-20 which should match your transcripts and diploma – List employer’s name as it is listed in E-verify along with their e-verify number. If you are working at Vanderbilt you can find Vanderbilt’s E-Verify information here.
    5. Form G-1145 completed
    6. Copy of transcripts and diploma; I-94 front and back; passport ID page(s) including expiration date; Visa stamp; all previous EAD cards
  • Once the above information is received by ISSS, your International Student Adviser will review your application materials, issue a new I-20 with STEM OPT recommendation, and finalize your STEM OPT Application Package.
