OPT STEM Extension

General Information

Definition of STEM OPT

Practical work experience in your field of study, typically after completion of a degree for a maximum of 36 months (12 months of “regular” OPT with a 24-month extension possible).

Eligibility Criteria for the 24-month OPT extension

  • Students who have already been approved for 12 months of post-completion OPT; and
  • Who have earned a bachelor’s or higher degree in a field included on the U.S. Government's list of Science, Technology, Engineering, and Mathematics (STEM) fields within the last 10 years; and
  • Who are employed in a paid job directly related to his/her field of study; and
  • Who have a job or job offer with an employer enrolled in the U.S. Government's E-Verify program.

Please Note: All four of the above criteria must be met in order for a student to be eligible for the 24-month OPT extension.

List of degrees in STEM fields

If a student earned a degree in a field that appears on the U.S. government's official list of STEM fields, he/she may be eligible for the 24-month OPT extension. In order to verify that your degree is on this list, look at the major code(s) listed in the "Program of Study" section 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 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 https://www.e-verify.gov/.

Application time frame for the 24-month OPT extension

Students must apply for the 24-month 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, International Center will process a STEM recommendation I-20 no more than three months and one week in advance of your current OPT end date. *Please note: you cannot apply during the 60 day grace period.

Work authorization status while STEM extension is pending: If you successfully file the application for your 24-month OPT extension prior to the expiration of your current 12-month OPT period EAD, you may continue employment even if your previous EAD card is expired until your OPT extension is processed or until 180 days has passed, whichever is sooner.

Additional Information

Reporting requirements during the 24-month extension

Students approved for the 24-month OPT extension have additional reporting requirements in order to maintain their status and work authorization. Students must report to the IC within 10 days if there is any change of:

  • Legal name
  • Residential or mailing address
  • Employer name
  • Employer address, and/or
  • Loss of employment

Students must make a validation report to the IC every six months to confirm name and address, employer name and address, and continuation of employment. The report is due within 10 days of the six-month reporting date. Use the STEM Extension Reporting Requirement web form to submit your validation report.

Types of Employment Allowed during an OPT STEM extension

A student authorized for a 24-month extension must work at least 20 hours per week for an E-Verify employer in a paid position directly related to his or her DHS-approved STEM CIP code.

For students who are on a STEM extension, this employment may include:

  • Work for one or more employer. Students may work for more than one employer, but all employment must be related to each individual student's degree program and all employers must be enrolled in E-Verify.
  • Multiple employers. Students may work for more than one employer, but all employment must be related to each individual student's degree program and all employers must be enrolled in E-Verify.
  • Self-employed business owner. Students on a STEM extension can start a business and be self-employed. In this situation, the student must register his or her business with E-Verify and work full time. The student must be able to prove that he or she has the proper business licenses and is actively engaged in a business related to his or her degree program. HOWEVER, under the new STEM regulations, students may not fill out their own Form I-983, Sections 3 to 6, nor act as their own employer for the purposes of the form. This might result in the student NOT being eligible for a STEM extension if self-employed.
  • Employment through an agency or consulting firm. ** details to come.

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.

Starting and Ending Dates

The start date of the 24-month OPT extension will be automatically set to the day after the expiration of the current 12-month OPT authorization. The end date will be 24 months later. (It is not possible to request smaller increments of time for the OPT extension.)

Application Procedures for Students

  1. Submit electronic OPT STEM Extension I-20 Request Form on or after May 10, 2016. Please make sure to fill out all the fields and attach all the documents listed in the form.

This is a new form that requires information from both the student and the employer. For assistance in completing this form, please view our U-M I-983 Instructions. For more information, please see the Study in the States website.

    Note for applicants who are employed by U-M: once your OPT STEM Extension I-20 Request is received and approved by an IC advisor, the advisor will send an e-mail to your U-M supervisor with the university E-Verify number information. You will need this number for your OPT extension application with USCIS. Please ask your supervisor for the E-Verify number after you have been notified by an advisor that your request has been received.

  2. IC will prepare a new I-20 for you. In most cases your I-20 will be ready in 1-2 weeks. We will notify you via email once it is ready. If you are located close to U-M, you may come to the office to pick up your new I-20. If you are located far away from U-M, you may authorize a friend to pick up your I-20 or we can send it to you either via express mail (recommended) or via regular mail. Find more specific information and forms at Shipping Options.
  3. Checklist for mailing your application to USCIS
    Once you've requested a STEM recommendation through the U-M International Center and received your new I-20, you will need to prepare and submit an application packet to USCIS. Gather the following items in this order (from top to bottom):
    • Base Fee for I-765, payable to U.S. Department of Homeland Security. Personal check, cashier’s check, or money order is acceptable.
