The 24-Month STEM OPT Extension Information Page

An Introduction to the 24-Month STEM OPT Extension

Former students engaged in standard Optional Practical Training (OPT) based on a bachelor’s, master’s, or doctoral degree in a qualified STEM field can apply to USCIS for a one-time (per degree level) 24-month extension.  When and how to apply for the STEM OPT Extension varies slightly from that of the standard Post-Completion OPT.

Those interested in applying for the STEM OPT Extension must contact their International Student Advisor well before the end of their standard Post-Completion OPT authorization period (the expiration date listed on their OPT EAD Card), to allow for ample time for advising, issuance and mailing of the new I-20 with the STEM OPT recommendation.   The application for the STEM OPT Extension must be submitted and received by USCIS prior to the expiration date of the current OPT EAD Card.

The STEM OPT Extension may be issued for a prior STEM degree obtained by the student, as long as that student is in a current period of post-completion OPT. Students may apply for the STEM Extension once per degree level, two times, over the course of their career.

Eligibility for the STEM OPT Extension

In order to be eligible for this extension, students applying for this benefit must:

  • Already be on valid OPT based on a STEM-eligible degree.
  • Have had fewer than 90 days of unemployment while on OPT
  • Be employed by, or have a job offer from, an employer who is registered in the E-Verify employment verification system
  • The student must have a job directly related to the STEM major and the employer must be registered with E-Verify (

When To Apply for the STEM OPT Extension

It is important to be aware of the rules surrounding the STEM OPT Application Process. An application that is received by USCIS too early, or too late, may be rejected.

  • Earliest date to apply for the 24-month STEM OPT Extension: No more than 90 days before the current OPT EAD Card expiration date
  • Latest date to apply: the application for the 24-month STEM OPT Extension must be filed (and received by USCIS) before the OPT EAD Card expiration date

 Applicants should note that the STEM OPT Extension application takes more time, and requires additional documentation, than the application for standard post-completion OPT application.  Applicants should take care to familiarize themselves with this process, and to contact their International Student Advisor well in advance of the expiration date of their OPT EAD Card; doing so will ensure ample time for issuance and shipping of the new I-20 with the STEM OPT recommendation.

Maintaining Your F-1 Status While on the STEM OPT Extension and Completion of the STEM OPT Extension

Reporting Requirements & Maintaining Legal Status during STEM OPT

While on OPT, students are responsible for reporting  any of the following changes to their International Student Advisor:

  • Student name
  • Current physical address
  • Name of current employer
  • Address of current employment
  • Start date of current employment
  • End date/date of termination, or any interruption, of employment
  • Any change in your home address, each time that you move
  • Any change in the name AND/OR the address of your employer by submission of a new I-983 form
  • You and your employer agree to submit a new I-983 form to update your employment information as soon as a material change occurs, and within 10 days of each 12-month evaluation.
  • You will “check in” with your DSO every 6 months to verify that your contact and employment information is accurate.

Unemployment During the OPT STEM Extension

Students on their 24-month STEM OPT Extension may not accrue an aggregate of more than 150 days of unemployment during the total OPT period, inclusive of any period of unemployment accrued during the original 12-month post-completion OPT period.

Students with STEM OPT Extension authorization who are unemployed for more than 150 (including days of unemployment during the 12 months of post-completion OPT) days are in violation of their immigration status.

Travel While on OPT

Students on post-completion OPT are permitted to return to the U.S. to resume employment. If you are on OPT and are outside of or plan to leave the U.S., and you do not have a job offer at the time of re-entry, it is possible you will not be permitted to re-enter the U.S. Also, if you have an I-20 with a Cap Gap notation and an expired EAD card, it is possible you will not be permitted to re-enter the U.S. The following are required in order to re-enter the U.S. to resume employment under OPT:

  • A valid passport
  • A valid F-1 visa (waived for those exempt from the visa requirement)
  • Your current original I-20 with a valid travel signature (no older than 6 months). If you need a new travel signature, please contact your DSO well in advance of your anticipated travel date
  • Your Employment Authorization Document (EAD)
  • Evidence of a job or job offer

You may experience difficulties or may even be denied re-entry if you try to return to the U.S. without any of the above items. It may also be helpful to travel with your documentation of financial support and a copy of your transcript or other academic record.

Completion of OPT

F-1 students can remain in the U.S. for a 60-day grace period after the  STEM OPT Extension period ends.  Employment is not permitted during the 60-day grace period.  Upon departure from the U.S., re-entry during the 60-day grace period as an F-1 student is not permissible.

Students on the STEM OPT Extension  who have reached a total of 150 days of unemployment (an aggregate between standard Post-completion OPT and the STEM Extension) do not have a 60-day grace period and must leave the U.S. immediately.

Upon completion of, or at any time during OPT, students may transfer their F-1 status to another U.S. institution. It is important to note that a transfer of F-1 status prior to the OPT end date automatically cancels any remaining OPT time. Students who want to transfer their F-1 status at the end of their OPT simply need to contact their DSO (your DSO will need a copy of your notice of admission to the new program and the name and contact information for the international student advisor at the new school).  Transfers of the  F-1 status (SEVIS record) should be done prior to the end of the 60-day grace period.

Students who have been approved for H1 status and who have a Cap Gap notation on their I-20 are permitted to remain in the U.S. beyond the 60-day grace period.
