OPT Extension

What is the OPT STEM Extension? 

The OPT STEM Extension is a 24-month extension of Post-Completion OPT work authorization for individuals who are engaged in Post-Completion OPT based on a bachelor's, master's, or Ph.D in certain STEM (Science, Technology, Engineering, Math) fields.

Who is Eligible for the OPT STEM Extension?  

 F-1 students who:

  • are on OPT following completion of a STEM degree
  • are currently on post-completion OPT and have only worked for a U.S employer in a job directly related to student's STEM field listed on I-20
  • have or will have an employer registered with E-verify
  • have never had a previous OPT STEM Extension (STEM Extensions provide a once in a lifetime authorization)

What is E-verify?

E-verify is a program that electronically compares information on the I-9 form with Social Security and DHS records to help employers verify identity and employment eligibility of new hires. It is currently free in all 50 states. Your employer can register with E-verify at www.uscis.gov.

When should I apply for the OPT STEM Extension?  

An F-1 student must apply for the STEM Extension in the 90 days window before the current EAD expires. You cannot apply more than 90 days before your OPT is scheduled to expire.  You must submit your OPT STEM Extension application maetrials to USCIS no later than 60 days after the I-20 with the OPT STEM recommendation was created.

When can I begin my STEM Extension work?  

The STEM Extension work authorization begins on the day after the expiration of the initial post-completion OPT authorization, and ends 24 months later, regardless of the date the actual extension is approved. Students who timely file a STEM Extension application will be able to continue employment with the E-verify employer while the extension application is pending, until adjudication or for 180 days, whichever comes first.  

Can I change employers during the OPT STEM Extension?  

Yes. However, you can only change employment to another employer registered with E-verify. The employment must also be directly related to your STEM degree. It is NOT recommended to change E-verify employers while the application is pending with USCIS since the I-765 names a specific employer.  

Can I remain unemployed during my OPT STEM Extension?

During this time, your F-1 status is dependent on employment. Students must not accrue an aggregate of more than 120 days of unemployment during the total 36 month OPT period.  

What are my reporting requirements while on the OPT STEM Extension?

STEM OPT students must report to the the Office of International Admissions every 6 months following the start date of the 24-month extension, even if there is no information to update.  The student must report: legal name, residential or mailing address, e-mail address, employer name, and employer address.  Students can report this information starting 15 days before the reporting date and up to 31 days after.  SEVIS will automatically terminate a student's OPT and F-1 status if the student fails to report to his/her school within this timeframe. This information is to be reported at: international@sunypoly.edu with "OPT STEM REPORTING" in the subject line of your email.  In addition, please complete form OPT STEM REPORTING.

What if I have a Bachelor's Degree in Actuarial Science but my current OPT is based on my MBA? Am I eligible?  

No. To be eligible for the OPT extension, the student must currently be in an approved post-completion OPT period based on a designated STEM degree.   If my primary major is not a STEM degree but my secondary major is in STEM, do I qualify?   Yes, as long as the secondary major is listed on your I-20 and your current OPT work directly relates to that major.
