STEM OPT Employer Responsibilities

The 24-Month STEM extension of OPT is a temporary employment authorization available to eligible F-1 students whose degree is on the STEM (Science, Technology, Engineering, Mathematics) Designated Degree Programs list following Post-Completion Optional Practical Training (OPT).
  • Eligible students will receive a 24-month extension of OPT for a maximum of 36 total months of OPT authorization.
  • A student who has been granted a 24-month extension of OPT cannot accrue more than 150 days of unemployment.
    • Students must not exceed 90 days of unemployment time before applying for the 24-month STEM extension.
    • Students that applied for a 17-month STEM extension must not exceed 120 days of unemployment time before applying for the 7-month STEM extension.  Once the student is approved for the 7-month STEM extension, the student is then eligible for the full 150 days of unemployment.
  • 24-month extension of OPT employment can only be with an E-Verified employer.
  • The following types of employment can no longer be counted as fulfilling employment requirements during the 24-month extension of OPT:
    • Part-time employment under 20 hours per week;
    • Volunteering;
    • Self-Employment or sole proprietorships;
    • "Start-Up" businesses that do not adhere to regulatory requirements as outlined in Form I-983;
    • Employment through "temp" agencies, consulting firm arrangements that provide labor for hire; and
    • Other employment situations that do not constitute a bona fide employer-employee relationship.
Please refer to the links below of information regarding the 24-month STEM Extension:

Applicants whose degree is on the STEM (Science, Technology, Engineering, Mathematics) Designated Degree Programs lists, available for review at The degrees are listed using Classification of Instructional Programs (CIP) codes developed by the U.S. Department of Education's National Center for Education Statistics. ISS has no role in determining which CIP code corresponds to each major or which majors are eligible for the 24-month extension of OPT.
  • Applicants must have been granted Post-Completion OPT and must be in legal immigration status.
  • Applicants who have accrued less than 90 days of unemployment during their initial Post-Completion OPT.
  • Applicants who will be employed in a position directly related to their field of study and commensurate with their education level.
  • Applicants who will be working for an employer that is enrolled in E-Verify. For more information on E-Verify, please visit
  • Applicants who have not received more than two previous STEM extensions of OPT.
  • Applicants who have previously earned a STEM degree at an SEVP-approved institution and have not yet participated in a STEM Extension for that degree.
Students must not exceed 90 days of unemployment time before applying for the 24-month STEM extension.‚Äč
The applicant must apply before the current period of Post-Completion OPT authorization expires. USCIS will accept applications for STEM Extensions up to 90 days prior to the expiration date listed on the student’s current EAD card.
Students must complete a two-part application process in order to apply for a STEM OPT Extension, as outlined below.
  1. Obtain ISS Recommendation for STEM OPT Extension: Students must first apply for a STEM OPT Recommendation by submitting the following documents to ISS by email at or by dropping the paperwork off at the ISS office on the campus of Texas A&M University.
    1. 24-Month STEM Extension Form
    2. DHS Form I-983
    3. Copies of the F-1 student’s most recent I-20 and I-94 record 
    4. A legible copy of the applicant's current EAD card (front and back) clearly depicting the OPT start and end dates
  1. Mail the STEM Extension Application to the appropriate U.S. Citizenship and Immigration Services (USCIS) Service Center: After receiving an updated I-20 from ISS with the appropriate STEM OPT Recommendation, students must then submit an OPT and EAD Card application to USCIS for processing.  USCIS will review the STEM extension of OPT application (this can take 2-3 months). If the application is approved, USCIS will issue a new Employment Authorization Document (EAD).
  • Requests with invalid employer E-Verify information will be denied and, if time permits, the student will have to reapply with the correct Employer E-Verify information. Please make sure your student has the correct E-verify number to input on Form I-765 of the USCIS application packet.
  • ISS recommends that students retain copies of all information that are sent to USCIS. It is good practice to use a mailing method that provides delivery confirmation. If your employee asks, please advise them on U.S. mailing practices.
  • It is recommended that students send a copy of the Form I-983 along with the USCIS STEM application, even though it is not required by USCIS at this time, so this form should be completed in full and accurately.
While you are on the STEM extension of OPT, you will need to abide by the STEM OPT Reporting Requirements as listed below:
  • General Reporting: Update ISS with any changes to your legal name, address, and phone number within 10 days of a change.  You can update your address and phone number in the Howdy Portal.

    • Self-Evaluations: The self-evaluations on Form I-983 are due at 12 and 24 months from the start date of your STEM OPT period.  You can submit these self-evaluations by emailing the updated Form I-983 and the OPT Employment Reporting Form to
    • Material Changes in Employment: If there are any of the following material changes in your employment, you are required to submit a modified Form I-983 to ISS as soon as you are able to do so:

      • Any reduction in student compensation that is not tied to a reduction in hours worked;
      • Any significant decrease in the number of hours of work per week that was specified on Form I-983;
      • Any decrease in the number of hours worked; and
      • Changes to the employer’s commitments or student’s learning objectives as documented on the Form I-983.
    • End of Employment Reporting: If your employment ends, the following must be submitted to ISS within 5 business days of the termination of your employment.
