F-1 STEM OPT Extension

The 24-month extension of Post-Completion OPT is for students who have completed a degree listed in the STEM Designated Degree Program List. Students who have completed a previous degree in a STEM designated program from a U.S. institution within the past ten years and have completed a new degree at Northwestern University are also eligible for STEM OPT Extension. 

To verify whether you qualify for the STEM OPT Extension, check the STEM Designated Degree Program List and verify your program name and the CIP code for your major found on page 1 of your I-20 under Program of Study. 

Eligibility Requirements for STEM OPT Extension

  1. Your program listed on your I-20 must be listed in the STEM Designated Degree Program List.

    The Department of Homeland Security (DHS) maintains a complete list of fields that fall within the regulatory definition of “STEM field” that qualifies certain degrees to fulfill the STEM OPT extension requirement. This list is known as the STEM Designated Degree Program list.  

    The  Northwestern Academic Programs and CIP Codesalso identifies programs with a STEM eligible CIP code. Please note this list is organized first by education level (Bachelor's, Master's, Doctorate) and then by CIP Code, in numerical order within each education level. 

  2. You must currently be employed or have a job offer from an employer registered with E-Verify
  3. Your employer/supervisor must complete the Form I-983 Training Plan for STEM OPT Students. The form is to be completed jointly by the STEM OPT student and employer/supervisor.
  4. You must apply before your post-completion period of OPT expires, and your application must be sent to USCIS within 60 days of the date the STEM OPT Extension I-20 was issued and signed by the OISS Advisor. You may apply up to 90 days before your post-completion OPT expires. Please note that you may continue to work up to 180 days while your STEM OPT Extension application is pending with USCIS and you have your receipt notice.

Ending STEM Extension, Departing the U.S., and Changes of Status

While on STEM OPT, you continue to hold F-1 status sponsored by Northwestern University and your F-1 record remains active in SEVIS. It is extremely important that you notify your OISS advisor of any changes to your immigration status.

If you are planning to leave the U.S. permanently

You must notify OISS BEFORE you leave the United States and submit a completed final employment evaluation from page 5 of the Form I-983 within 10 days of changing your status (leaving your job). You can submit your evaluation and employment end date by submitting the OPT/STEM OPT Employment Update at the OISS Portal.

If you change to another visa status in the U.S.

If you change to another visa status in the U.S., such as H-1B, E-3, G-4, TN, etc. or obtain Permanent Resident status, you must notify your OISS advisor. To report this change, you will need to send your advisor evidence of your new status (e.g. new I-94 arrival/departure record, I-797, or green card). You will also need to submit a completed final employment evaluation from page 5 of the I-983 within 10 days of changing your status.

Frequently Asked Questions

What are CIP codes?

Classification of Instructions Programs (CIP) codes are published by the National Center for Education Statistics (NES).   Your CIP code determines whether your major has been designated as a STEM major eligible for the STEM OPT Extension. The U.S. Department of Homeland Security (DHS) STEM Designated Degree Program List is a complete list of fields of study that DHS considers to be science, technology, engineering or mathematics (STEM) fields of study for purposes of the 24-month STEM optional practical training extension.

My department changed CIP codes. Can I apply for the STEM OPT Extension?

There is an administrative process that NU departments must go through to change the CIP code. Once the CIP code change has been approved, the NU registrar updates the CIP code based on the parameters of the approval. After the registrar updates the CIP code, the OISS will update the CIP codes in SEVIS. You may request a new I-20 with the updated CIP code. Please request a reprint for your I-20 via the OISS Portal. In the request, please choose Other from the drop down and explain that your CIP code changed in the area provided.

Once the CIP code has been updated, you may meet the CIP code requirements for STEM OPT Extension eligibility.

Can I apply for the OPT STEM Extension based on a prior degree?

If you otherwise qualify for the STEM OPT Extension and can fill-out the I-983 training plan with your current employer outlining how you are using your STEM coursework in your job, you can apply for the STEM OPT extension based on a previously earned degree as long as both degrees were received from currently accredited educational institutions.

You will need to contact your OISS Advisor to initiate a STEM OPT Extension request based on a prior degree. 

Can I apply for STEM OPT more than once?

If you complete another STEM-eligible degree at a higher academic level, you may apply for a second 24 month period of STEM OPT if you otherwise meet the STEM OPT Extension qualifications.

What is the H-1B Cap- Gap Extension?

A cap-gap extension is a regulatory provision which extends an eligible F-1 student's status to bridge the gap between the end of F-1 status and start of H-1B status, thereby allowing the student to remain in the U.S. during the "gap”. The cap-gap extension is available to students who, as of April 1st, were either on approved OPT or in their 60-day grace period and have a pending or approved change-of-status H-1B petition with USCIS that was filed in a timely manner.

To qualify for the "H-1B cap-gap extension" you must be in valid F-1 status, and you must be the beneficiary of an H-1B petition that meets all of the following:

  • Has been timely filed.
  • Requests an employment start date of October 1 of the following fiscal year
  • Requests a change of status

Cap-Gap extensions cannot be used if you will be in H-1B status in a non-profit or research educational institution.

For more information, please contact your OISS advisor.
