STEM OPT Extension

STEM OPT is an extension of the Optional Practical Training (OPT) program in the US. It allows F-1 students who have earned degrees in Science, Technology, Engineering, or Mathematics (STEM) fields to extend their work authorization for an additional 24 months beyond the initial 12-month OPT period. This extension is designed to provide students with more time to gain practical experience in their field of study.

USCIS may take 2 to 4 months to process STEM OPT applications, so we strongly encourage eligible students to apply as early as possible. To apply, please follow the instructions below carefully.

When to apply for STEM OPT: You must currently be on OPT. If you are still in your program, you must apply for OPT first, and then you can apply for STEM OPT 90 days before your regular OPT ends.

How to Apply for STEM OPT

Step 1) Learn About STEM OPT

There's a lot of information about STEM OPT, so it's crucial to learn as much as you can before you begin applying. First, watch the following video:

Be sure to inform your assigned international advisor that you intend to apply for STEM OPT before your current OPT expires!! ISSS is not responsible for last-minute STEM OPT application requests. It is the student's responsibility to file for STEM OPT in a timely manner. Remember, you must apply for STEM OPT before your OPT expires!

What is STEM Optional Practical Training (STEM OPT)?

STEM OPT is an extension of the special work authorization called OPT for students studying in majors related to Science, Technology, Engineering, and Math (STEM). STEM OPT is an extension of OPT that is only available for STEM students.

How long can I do OPT and STEM OPT?

Student Exchange Visitor Program (SEVP) regulations allow up to 12 months of OPT at each increasing degree level for a student in F-1 status. Science, Technology, Engineering, and Math (STEM) students are eligible for an extension of 24 months of OPT, meaning that the total of optional practical training can be 36 months (3 years).

When can I apply for STEM OPT?

The student must first be on regular OPT. Then, the student can file for the STEM OPT extension online up to 90 days prior to the student's regular OPT expiration date as seen on their EAD card. The student cannot apply for STEM OPT after the expiration date.

Failure to apply before OPT expiration, or to file last-minute without sufficient I-20 processing time, will result in the closure of STEM OPT opportunity. Then, the student will have a 60-day grace period to leave the US, enroll in a new program, or transfer to a new university.


We strongly encourage students to apply for STEM OPT as soon as possible, as it can take USCIS two to four months to adjudicate applications.

See USCIS's current I-765 (OPT application) processing times here.

Once your international advisor provides you with the special I-20 required for your online application, you must submit it within 60 days of the I-20 issuance. Failure to adhere to this regulation, and submitting your STEM OPT application with an expired I-20, will result in denial of your STEM OPT application and may cause you to fall out of F-1 visa status. Please be advised.

How long does it take for a STEM OPT application to be approved?

It may take USCIS two to four months to process a STEM OPT application. You can review current I-765 (OPT Application) processing times here.

Processing times are unpredictable and subject to change without notice, so we strongly recommend applying as early as possible!

USCIS provides students who timely filed for STEM OPT with an automatic 180-day grace period from the date their OPT card expires to continue working while their STEM OPT application is being processed (source). However, once the 180-day grace period is over, the student cannot continue working if the application is still pending.

Step 2) Receive Special I-20

After watching the video and consulting with your international advisor, you'll need a special I-20. The special I-20, also called an "STEM OPT Recommendation Letter" is issued specifically for your STEM OPT application.

To receive the special I-20, email your international advisor the following documents:

  1. Completed STEM OPT Acknowledgement Form - This form outlines all the regulations and information you need to know about STEM OPT. Although this form is not needed in your online application, TTU International Affairs requires it to ensure you understand STEM OPT guidelines.
  2. Completed I-983 Form - This form must be filled out by you and your employer. Please use the I-983 Guide to assist you with each section. Remember that your employer must be e-verified and employment must be related to your degree and 21 or more hours a week.

Once your international advisor reviews your valid documents, they will issue the special I-20 which you will use to submit in your online STEM OPT application.

*Note: USCIS must receive your STEM OPT application within 60 days of the special I-20 issue date! This means that after you receive the special I-20 from your international advisor, you must file your application as soon as possible or it may result in the denial of your STEM OPT application!

Step 3) Submit Online STEM OPT Application

After receiving your special I-20, please print it out, sign it with wet, black ink, and scan it again to use for your online STEM OPT application.

Now it's time to submit your online STEM OPT application, also called an I-765 Form. You will do this in your previous myUSCIS account here, or you can create a new account. Please follow along with this detailed, step-by-step OPT PowerPoint Guide to proceed:

Payment & EAD card

The online application will require an I-765 fee payment. When you've received confirmation of your payment (also called a Form I-797 Receipt Notice), your application is completed. USCIS will send your EAD card to the mailing address provided in your STEM OPT application, but if your mailing address changes, you must inform USCIS in your myUSCIS account and your international advisor for further assistance.

EAD Card Example

Please remember to provide a copy of the front/back of your EAD card to your international advisor. Then, they will provide you with STEM OPT reporting requirements necessary to maintaining your F-1 status. These requirements are different from the reports you made during OPT!

180-Day Grace Period

USCIS provides students who timely filed for STEM OPT with an automatic 180-day grace period from the date their OPT card expires to continue working while their STEM OPT application is being processed (source). However, once the 180-day grace period is over, the student cannot continue working if the application is still pending.

STEM OPT Reporting Requirements

For the full list of STEM OPT Reporting Requirements, please visit Study in the States here. 

STEM OPT REPORTING REQUIREMENTS

Per the requirements listed in your STEM OPT Acknowledgment form, you will be required to report any changes in your address, phone number, or employment within 10 days of the change. While you will still be able to report changes in your personal address or phone number through your SEVP Student Portal account, you will no longer be able to report changes in employment yourself in the Portal account once on STEM OPT.

Please follow this procedure to report any new or ended employment on STEM OPT: 

  1. For Ended Employment: Complete and email your international advisor the “Final Evaluation on Student Progress” page (second half of page #5 of the I-983) from your previous employer. Be sure to include your employment end date in this evaluation.
  2. For New Employment: Complete a new I-983 with the new employer and email it to your international advisor.

You additionally will have a six-month STEM OPT check-in and an annual evaluation from the I-983 due during your STEM OPT, per the requirements listed in the STEM OPT Acknowledgment form. Your validations are due exactly after 6, 12, 18, and 24 months counting from the start date of your STEM OPT EAD authorization (not the start date of your employment with your company). You will need to verify the following information for your international advisor, even if it has not changed:

  1. SEVIS ID Number:
  2. Current Home Address:
  3. Current Email Address (non-TTU):
  4. Current Employment Information (name and address):
  5. First Date of Employment during STEM OPT period:

The “Evaluation on Student Progress” from page #5 of the I-983 is due at the end of your first year of STEM OPT. This evaluates your first year of STEM OPT. The “Final Evaluation on Student Progress” is due at the end of your second year of STEM OPT and evaluates the second year, or if you end employment. Please email your international advisor these forms when they are due.

If you created your SEVP Student Portal account, then your Portal account will send you automated email reminders whenever you have the six-month check-in and/or annual reports due. 

For further questions, please contact your assigned international advisor.

Information for STEM OPT Employers

Employers play a key role in maintaining and strengthening the integrity of the STEM OPT extension program. Although compliance with the program's various reporting requirements predominately apply to students and their universities, there are instances where STEM OPT employers must assist in tracking the STEM OPT students and their practical training progress. Employers must be registered in E-Verify to employ international students on STEM OPT. In addition, the employment opportunity must be full-time (at least 21 hours per week). Review Study in the States STEM OPT Reporting Requirements here for more information.

DHS requires that the STEM OPT student and employer work together to complete the form I-983. Properly completing this form will successfully document the relationship between the STEM OPT opportunity, the academic degree received, and the learning objectives of the F-1 student.
Review the Study in the States Guide for I-983 Forms here for more information.


Site visits are when DHS officials visit the student's site of employment to ensure that STEM OPT students receive structured and guided work-based learning experiences and reduce the potential for abuses of the STEM OPT extension. During a site visit, DHS's intent is to confirm that information reported on the student's I-983 Form concerning the training opportunity is accurate, while not placing an unnecessary burden on employers. Review the Study in the State Site Visits here for more information.

We strongly encourage students to apply for STEM OPT as soon as possible, as it can take USCIS two to four months to adjudicate applications.

See USCIS's current I-765 (OPT application) processing times here.

Once your international advisor provides you with the special I-20 required for your online application, you must submit it within 60 days of the I-20 issuance. Failure to adhere to this regulation, and submitting your STEM OPT application with an expired I-20, will result in denial of your STEM OPT application and may cause you to fall out of F-1 visa status. Please be advised.

3. How long can I do STEM OPT?

The Student Exchange Visitor Program (SEVP) regulations allow F-1 students who have earned degrees in Science, Technology, Engineering, or Mathematics (STEM) fields to extend their work authorization for an additional 24 months beyond the initial 12-month OPT period. This extension is designed to provide students with more time to gain practical experience in their field of study.

4. How long does it take for a STEM OPT application to be approved?

It may take USCIS two to four months to process a STEM OPT application. You can review current I-765 (OPT Application) processing times here.

Processing times are unpredictable and subject to change without notice, so we strongly recommend applying as early as possible!

USCIS provides students who timely filed for STEM OPT with an automatic 180-day grace period from the date their OPT card expires to continue working while their STEM OPT application is being processed (source). However, once the 180-day grace period is over, the student cannot continue working if the application is still pending.

5. Do I need a job offer to apply for STEM OPT?

Yes, the student must secure an e-verified employer to apply for STEM OPT. The employer must assist the student in filing the I-983 form required to apply for STEM OPT. The employment must also be related to the student's STEM degree and provide 21 or more hours of work a week.

6. Am I still an F-1 student while on STEM OPT?

Yes. STEM OPT is only a work authorization for F-1 students, therefore, you are still an F-1 visa student and must continue to abide by F-1 visa regulations.

7. When should my STEM OPT Start Date be?

The STEM OPT start date is automatically the day after your regular OPT expires, even if you have not received your STEM OPT EAD card yet. You will be given an automatic 180-day grace period to continue working after the new start date on STEM OPT until your application is adjudicated. You cannot continue working once the 180-day grace period ends if your application is still pending, but you may start work again once the application is approved.

8. What do I do if my STEM OPT application has been pending for too long?

If you apply for STEM OPT and it is pending longer than the 180-day grace period you have after your regular OPT expires, you will still remain in status until the STEM OPT application is adjudicated. If the application is taking longer than the expected USCIS's I-765 processing times, you may be eligible to submit an inquiry via USCIS's e-Request website here.

You can also consider filing for Premium Processing for an additional fee by following the instructions here. Premium Processing guarantees that your application will be adjudicated in 30 calendar days, plus 1-3 weeks shipping time to receive your EAD.

9. How many unemployment days do I have on STEM OPT?

When you began regular OPT, you started with 90 unemployment days. If none of those days were used, you will receive an additional 60 days for STEM OPT, totaling 150 unemployment days. Remember, it is the student's responsibility to keep track of all accrued unemployment days. You may be able to review your unemployment days in your SEVP portal.

Unemployment days do not reset once STEM OPT begins. Your unemployment days used from regular OPT will "roll over" into your STEM OPT period. For example, if you accrued 20 unemployment days during regular OPT, then you would have 130 unemployment days remaining for your STEM OPT period.

10. What happens if all my 150 unemployment days are used?

BEFORE  you exhaust your 150 unemployment days, you must take action in one of these:

  • Leave the country
  • Receive admission for a new program at TTU (a new I-20 must be issued before the end of the 150 days)
  • Transfer out to a new school (SEVIS record must be released before the end of the 150 days)
  • Apply for a new visa status, commonly an H-1B (Please consult an immigration attorney for further assistance)
  • Find full-time STEM OPT employment related to your major with an e-verified employer to stop the unemployment clock

11. What kind of jobs can I have during STEM OPT?

All employment must be e-verified, related to your STEM OPT degree, and reach 21 or more hours a week (full-time).

12. What's the difference between EIN and E-Verify?

Be aware that EIN and E-Verify numbers are completely different numbers.

  • Your I-983 form will ask for the 9-digit EIN number.
  • Your online STEM OPT application will ask for the 4-7 digit E-Verify number.
Your employer will know which numbers you will use. Please ensure to use the correct number in the appropriate forms.

13. How many hours can I work during STEM OPT?

STEM OPT is for full-time employment only. In the immigration language, full-time employment means 21 or more hours.

14. Can I have more than one employer while on STEM OPT?

Yes, it is acceptable to work for more than one employer so long as each job is 21 or more hours, related to your degree, and both employers are e-verified.

15. Can I be self-employed while on STEM OPT?

No, self-employment is not eligible for STEM OPT. The US Department of Homeland Security has clarified that STEM OPT employment requires a bona fide employer-employee relationship between the student and the employer.

16. Can I travel while my STEM OPT application is pending?

Traveling with a pending application with USCIS is risky, as you are required to remain in the US until you receive your EAD card. There is also some risk that your SEVIS record may change while traveling (such as application approval/denial, or Requests for Evidence), and that you may re-enter with an outdated I-20 or miss time-sensitive requests from USCIS.

However, if you must leave the US during this time, please reach out to your international advisor.

17. Can I volunteer while on STEM OPT?

No, volunteer/unpaid positions are not allowed for STEM OPT employment.

18. What happens if I change my mailing address while my STEM OPT is pending?

If you are moving, you will need to update your address in your myUSCIS account here: How to Change Your Address | USCIS. If this does not work, you can file an AR-11 form online. You should also reach out to the United States Postal Office (USPS) to change your address as well to ensure you receive your EAD card.

Please inform your international advisor if your address has changed so they can update your records as well.

19. What happens if my STEM OPT is denied?

Please reach out to your international advisor immediately for further guidance and provide them with the official I-797 Denial Notice which details the reasons for which your STEM OPT was denied.

Your next steps will be determined by the timing of the denial and other factors which your international advisor will discuss with you.

20. What if my EAD card is lost in the mail?

First, you should contact both USCIS helpdesk here and the US Postal Service here to find out more information on where your EAD card is. Additionally, you can find assistance through the missing US Postal Service mail webpage here

If you learn that your EAD card may be lost for good, you can file for a replacement EAD card here, but please be advised that it will require the same fee as the original I-765 application.

Sometimes mail packages are delivered to your neighbors, so you may want to inquire with them as well.
