24-Month STEM OPT Application


F-1 students with degrees in STEM fields (science, technology, engineering, and mathematics) may apply for a 24-month extension of their current post-completion OPT status based on several requirements. The 24-month STEM OPT extension may not be divided and may be used twice in non-consecutive periods. Go to STEM OPT Hub for more information.


  • Applicant must currently be in a 12-month period of post-completion OPT.
  • Applicant has completed a degree in a current STEM eligible field from a current U.S. accredited institution with SEVP certification within the 10 years before the STEM OPT application date and has not already utilized this degree to apply for an STEM OPT extension.
  • Student must have at least 20 hours per week paid employment at a job in the U.S. directly related to their STEM degree.
  • The employer must be enrolled in USCIS’s E-Verify employment eligibility verification program.
  • The employer must provide the student with formal training and learning objectives. 

When to Apply

  • Students may apply for an extension up to 90 days before the end date of the current 12-month OPT.
  • The application must be received by USCIS before the end of your 12-month OPT.

Continuing Employment

  • Students who file in a timely manner will have their post-completion OPT automatically extended while the STEM OPT application is pending until a final decision on the STEM OPT request is processed or for 180 days, whichever is first.
    • Your Receipt Notice is proof of the timely filing. 

Important Information

  • Students may not accrue more than 90 days of unemployment from the start date on their 12-month EAD card during their 12-month post-completion OPT or up to 150 days with a STEM OPT extension.
  • Although it is possible to change employers and/or have multiple employers during the STEM OPT extension period, all employers must be enrolled in E-Verify.
    • All employment must be paid and at least 20 hours per week.
  • If a student changes employers during the STEM OPT extension period, they must submit a new Form I-983 (Training Plan for STEM OPT Students) within 10 days of leaving the previous employer. If the time between employers is longer than 10 days, the student must report the loss of employment to the OISS advisor and submit the I-983 later.
  • International students are exempt from paying Social Security and Medicare taxes for the first 5 calendar years they hold F-1 status but are required to pay all federal and state taxes.
  • F-1 students cannot qualify for STEM OPT extensions unless they will be bona fide employees of the employer signing the Form I-983 because F-1 students may not provide employer attestations on their own behalf.


We advise that you do not travel if your STEM OPT is pending and your 12-month OPT has ended. To return to the U.S. during STEM OPT, you’ll need the following documents:
  • STEM OPT I-20 signed for travel (valid for 6 months) on the 2nd page;
  • Valid visa (it is possible to renew a visa after STEM OPT approval but difficult with a pending application);
  • Passport valid for at least 6 months from the date you re-enter;
  • If your STEM OPT has not been approved - Form I-797C (Receipt Notice);
  • If your STEM OPT has been approved – STEM OPT EAD card and employment letter or contract;
    • If your STEM OPT is approved while you are out of the country, you will need to have your EAD card and an employment letter or contract in order to return;
  • Please note: re-entry after travel out of the country is never guaranteed. If your application is denied while you are out of the country, it may not be possible for you to return on the F-1 visa or to resume STEM OPT. 

Reporting Requirements

  • Employers are responsible for reporting the termination or departure of the student to the OISS within 5 business days after the student leaves employment. Employers must consider a worker to have departed when the employer knows the student has left employment or if the student has not reported to work for a period of 5 consecutive business days without the employer’s consent, whichever date is earlier.
  • EVERY 6 months starting from the date the STEM OPT extension starts and ending when the student’s F-1 status ends or the STEM OPT extension ends, whichever is first, students must submit the 24-Month STEM OPT Validation Report to OISS.
    • We highly recommend you add reminders to your calendar to remember to submit the validation reports.
    • This is also a good time to review the I-983 you submitted for your STEM OPT application to make sure all the information is still the same.
      • If anything has changed, upload a new completed I-983 with the appropriate signatures to the validation report.
  • You may use the SEVP Portal to report physical/mailing address and phone number updates and to view information regarding your STEM OPT, including reporting deadlines.
  • If your employment changes (add employer, change employers, stop/lose employment) during your STEM OPT, you  must report any employment changes to OISS within 10 days of the change by submitting the 24-Month STEM OPT Update Form and any required supporting documents.
    • If you have multiple employers, you must work at least 20 hours per week for EACH employer.
  • Students must complete the “Evaluation on Student Progress” portion of the Form I-983 within 12 months of the listed STEM OPT start date. At the end of the STEM OPT extension, student must complete the “Final Evaluation on Student Progress” assessment. Once the evaluations are complete, the student must collect signatures from their employer and submit the form to the OISS advisor.
    • If you change employers during STEM OPT, submit a final evaluation for that employer.
  • Both the student and employer are obligated to report to the OISS advisor any material changes to, or material deviations from, the student's formal training plan.
  • Go to Students: STEM OPT Reporting Requirements for detailed reporting requirements.
