The STEM OPT extension is only available to certain F-1 students who receive a qualifying degree in a STEM field at the bachelor’s level or higher from an accredited, SEVP-certified school. Students must be in their initial period of regular post-completion OPT to apply for the extension. The STEM OPT extension also involves additional forms and reporting requirements. F-1 students granted the STEM OPT extension by USCIS receive an additional 24 months of employment authorization for on-the-job training in their STEM field.

STEM OPT Eligibility

In order to be eligible to apply for STEM OPT, the following criteria must be met:

  1. The degree that is the basis for the 24-month OPT extension must be a Bachelor’s, Master’s, or Doctoral degree in a science, technology, engineering, or mathematics field that appears on the DHS STEM Designated Degree Program List at the time the DSO recommends the STEM OPT extension.
  2. The STEM degree (on the DHS List) that serves as the basis for the student’s currently active post-completion OPT period; or a previously-conferred STEM degree (on the DHS List), i.e. STEM degree that was conferred prior to the degree that serves as the basis for the student’s currently active post-completion OPT; within the last 10 years.
  3. Qualifying job must be a paid job, for at least 20 hours per week at each STEM employer.
  4. Employer must be enrolled in E-Verify and have an IRS Employer Identification Number (EIN); DHS says that there must be a “bona fide employer-employee” relationship and that the student may not be self-employed.
  5. The student and employer must complete the Training Plan for STEM OPT Students (I-983), and the student must present the completed I-983 to the DSO before the DSO recommends STEM OPT in SEVIS.
  6. USCIS must receive the student’s STEM OPT application package before the expiration of the student’s current post-completion OPT.

An eligible F-1 student can apply for the 24-month extension within 60-days of the DSO endorsement on your Form I-20, and up to 90-days before your current OPT employment authorization expires.

  • A student who has timely filed an application for a 24-month STEM OPT extension with USCIS may work for the STEM OPT employer while the STEM extension application is pending, for up to 180 days beyond the expiration of his or her post-completion OPT EAD. 
  • If a STEM OPT application is still pending more than 180 days beyond the expiration of the student’s regular or cap-gap OPT, the student must stop working.

STEM OPT employment authorization must be adjudicated by USCIS, after receiving the DSO endorsement and prior to beginning employment. Interested students should plan ahead and refer to the USCIS Case Processing Times for an estimated wait time.
