24 Month STEM Extension

F-1 students who receive science, technology, engineering, and mathematics (STEM) degrees, and who meet other requirements (see below) are eligible to apply for a 24-month extension of their post-completion OPT. As of May 10, 2016, the 24-month STEM extension replaced the 17-month STEM OPT extension previously available to STEM students.


All four of the below criteria must be met in order for a student to be eligible for the 24-month OPT extension:
  1. Students who have already been approved for 12 months of post-completion OPT; and
  2. Who have earned a bachelor’s, master’s or Ph.D. (certificate programs are not eligible) in a field included on the U.S. Government’s list of Science, Technology, Engineering, and Mathematics (STEM) fields within the last 10 years (see below for more details about how to find out if your degree is STEM eligible); and
  3. Who are employed for at least 20 hours per week in a paid job directly related to his/her field of study; and
  4. Who are working for an employer that is enrolled in the U.S. Government’s E-Verify program.
List of degrees in STEM fields

In order to verify that your degree is on U.S. government’s office list of STEM fields, look at the code listed under “Primary Major” on Page 1 of your I-20 form, and then look for that code in the CIP code column of the U.S. Department of Homeland Security STEM Designated Degree Programs list:

E-Verify Program

E-Verify is a database system operated by the Department of Homeland Security in partnership with the Social Security Administration. It allows participating employers to electronically verify the employment eligibility of newly-hired employees. E-Verify is currently voluntary in most states. For more information visit

24-Month Extension Available Twice

The 24-month extension of OPT is available to each student at TWO non-consecutive periods of time. Please note that this rule is different from the application rules for the “standard” 12-month OPT, under which students could be approved for multiple OPT periods for each higher degree earned in the U.S. (i.e. bachelor’s, then master’s, then doctoral). Each STEM extension must meet the above-listed STEM eligibility requirements.

24-Month STEM OPT Extension based on previous degree

Students now have the ability to apply for a STEM OPT extension based on a previously earned STEM degree from an accredited U.S. institution within 10 years under which the student has not previously applied for STEM OPT Extension. Example: a student had a bachelor’s degree in Engineering, didn’t have STEM OPT based on that degree, then got an MBA, received regular (12-month) OPT based on the MBA; the student is eligible (if meeting all other STEM OPT eligibility requirements) to apply for 24-month STEM OPT at the end of the 12-month OPT after his/her MBA.

Employment during STEM OPT

Restrictions on types of employment permitted during 24-month STEM OPT

  • Any job the student has on STEM OPT must be related to his/her program of study.
  • Students on STEM OPT are only allowed to work for e-verified employers.
  • Volunteering/unpaid employment is not permitted during the STEM OPT extension
  • Self-employment is not permitted during the STEM OPT extension

Travel Outside USA during STEM OPT

If you travel outside the United States or U.S. possessions during the approved STEM OPT extension period, to re-enter the country, you must present the following documents at the border:

  • Your passport valid for at least six months into the future and your unexpired F-1 visa stamp
  • I-20 with a valid travel signature. While you are participating in OPT, travel signatures are valid for only 6 months.
  • Your EAD card for STEM OPT Extension*
  • Proof of employment

*If your STEM OPT application is pending and you plan to travel abroad, please make sure your Post-OPT EAD is still valid. If your Post-OPT EAD is already expired, traveling abroad is NOT recommended.

When to apply

Students must apply for the 24-month STEM OPT extension prior to the expiration of the first 12 months of “regular” OPT. The application must be received by USCIS prior to the expiration date of the first OPT period EAD in order to be properly (timely) filed. USCIS will not accept I-765 applications for STEM extensions any earlier than 90 days before the current EAD expiration date. Accordingly, OGS will process a STEM recommendation I-20 no more than three months and three weeks in advance of your current OPT end date.

*You cannot apply for STEM extension after your Post-OPT EAD has expired.

Processing Time

  • The OGS requires 10 business days to process a request for STEM OPT recommendation.
  • Note that USCIS advertises normal processing time for STEM OPT requests as 90 days.
  • If you receive your EAD and there are errors on your card, please call the USCIS Customer Service line at 1.800.375.5283 to rectify any mistakes.

After the documentation leaves the respective Lockbox, it is forwarded to the USCIS Service Center where it is generally adjudicated within a period of 90 days. In about fifteen days of USCIS’ receipt of your application for the 24-month OPT extension, you should be receiving a Form I-797, a receipt notice from USCIS.

What happens after I submit my documents to USCIS?

  • You should receive a receipt notice from USCIS. You can look up your case status online using the case number.
  • Once your STEM OPT is approved, expect to first receive an approval notice and then an EAD card
  • While your 24-month OPT STEM extension application is pending, you may continue working for up to 180 days (6 months)*

*The period of the 24-month STEM OPT extension starts the day after the expiration of your original period of approved Post-Completion OPT. While your 24-month OPT STEM extension application is pending, you may continue working for up to 180 days (6 months). The Code of Federal Regulations, 8CFR 214.2(f)(11)(i)(C) and 8CFR 247a.12(c)(6)(iv), automatically extend your work authorization while the application is pending. However, you must have already submitted all the appropriate documentation to USCIS and paid the filing fee prior to the expiration date of your Post-Completion OPT.

Important reminders and most common application mistakes

  • Do not submit STEM OPT application to USCIS prior to obtaining I-20 with STEM OPT recommendation
  • USCIS must receive the STEM OPT application within 60 days of the STEM OPT recommendation by the OGS; if the application is not received by USCIS within 60 days after the issuance of STEM OPT I-20, the application will be denied.
  • Do not mail in your application so that USCIS receives it more than 90 days before your OPT EAD end date. Your application must be received by USCIS before your OPT EAD expires. Applications received outside of these times will be denied.
  • If your entire application is returned to you (in plastic), consult with an OGS Advisor before resubmitting the application; your application may not be considered “received” and you may need a new I-20 with STEM OPT recommendation.
  • Make sure that the address on I-765 is valid for receiving mail at all times while your STEM OPT is pending

Reporting Requirements


  • If you change employers while on STEM, you must update your Employer name and address within 10 days
    •  Note: If you change employers, you and your new employer will need to complete a new I-983 and submit it to the OGS.  You also must submit the “Final Evaluation on Student Progress” section of the I-983 for your previous STEM employer.
  • You and your employer(s) must report any I-983 Updates to the OGS; updates are required for the following:
    • Any change in of Employer Identification Number
    • Any reduction in your compensation that is not tied to a reduction in hours worked
    • Any significant decrease in your work hours per week
    • Loss of employment (within 5 business days of termination of employment)


  • The following updates are mandatory to report for all students while on STEM:
    1. 6 Month validation – You are required to confirm to the OGS every 6 months the validity of the following information (regardless if there is a change or not) Legal name, Residential address, Employer name and address, Status of current employment
    2. Evaluation on Student Progress(I-983) – You must submit “Evaluation on Student Progress” only after you have completed 12 months of the STEM employment with the same employer (Note: if you leave the employer prior to completing the 12 month during your STEM period, you do not need to complete this section.)
    3. Final Evaluation on Student Progress (I-983) – You must complete “Final Evaluation on Student Progress” for the following:
      • At the end of the 24 month STEM period
      • If you leave an employer at any time during the 24 month STEM period


Note: If you have more than one employer while on STEM, you will need to complete this for each employer.

Changing Employers during STEM OPT

Students on STEM OPT are allowed to change employers, but every employer they work for while on STEM OPT must be enrolled in E-Verify.


When a student leaves his/her 24-month STEM OPT employer, the student is required to provide his/her Final Evaluation on Student Progress (I-983). When a student starts working with a new employer, he/she must submit a new Form I-983 for the new employer. 


If your application is pending with USCIS

 A student who has a pending STEM OPT application can change employers, but the new employer must also be an E-Verify Employer. The student must report the change of employer to USCIS by doing the following:

  1. Submit the STEM Extension I-20 Request to OGS
  2. Send the following documents to USCIS (to the address on the STEM OPT application receipt notice, NOT to the lockbox address where the original application was mailed):
    • New Form I-765 (with new employer information)
    • Cover letter explaining why you are submitting new I-765 (change of employer) and referencing your pending case #
    • Copy of USCIS receipt notice
    • Copy of new STEM OPT I-20 (with updated employer information)

If your STEM OPT Application has already been approved

If a student changes his/her employer after the STEM OPT extension is approved, there is no need to notify USCIS about the change. The student needs to submit the update via Employer Update Form. You and your previous employer will need to complete the “Final Evaluation on Student Progress” on Form I-983.  You and your current employer will need to complete a new Form I-983.

Unemployment time during 24 month STEM OPT

Students are permitted an additional 60 days of unemployment under the STEM OPT period, in addition to the current 90 days of unemployment allowed during the 12 month post-completion OPT period; up to 150 days of total unemployment.

Additional information that must be reported to OGS

  • A decision to discontinue STEM OPT and depart the U.S.—Submit the Request to Complete OPT & SEVIS Record along with a copy of a flight itinerary indicating you have/will depart the U.S.
  • Change of status to a status other than F-1
  • A decision to begin a new program of study at Northeastern or transfer to another school in the US
