The 17-Month STEM Extension is employment authorization for certain science, technology, engineering, and mathematics (STEM) degree holders who are about to finish their regular 12 months of OPT and wish to request additional 17 months of OPT.

Eligibility Requirements

  • Student is currently authorized for post-completion OPT and is working for a U.S. employer in a job directly related to his/her field of study at the time of application.
  • The degree that was the basis for the student's current period of OPT is a bachelor's, master's, or doctoral degree listed on the current STEM Designated Degree Program List. A minor field of study cannot serve as the basis for a 17-month STEM OPT extension.
  • Student has a job-offer from or is employed by an employer registered with the "E-Verify."
  • Student has not received a 17-month OPT extension for a prior STEM degree. An individual is eligible for only one 17-month STEM OPT extension. According to SEVP, this is a lifetime limit.

When to Apply

A qualifying STEM degree holder may file the 17-month extension application up to 120 days before the current OPT end date. However, the STEM extension application must be received by USCIS within 30 days of the date on which UW-Platteville issues the new I-20 recommending the 17-month extension. In general, a 17-month extension application will take three months to be approved. However, a student's work authorization is extended for up to 180 days while the 17-month extension application is pending. Note, however, that employment must conform to STEM conditions during this interim extension period, including the requirement that the student work only for an E-Verify employer.

Employer's Responsibility

The employer must agree to report within 48 hours the termination or departure of a STEM OPT employee to UW-Platteville International Student Services office via e-mail (intlinfo@uwplatt.edu) with the subject line, "STEM OPT Employer Update" if the termination or departure is prior to the end of the authorized period of OPT. An employer shall consider a worker to have departed when the employer knows the student has left the employment, or if the student has not reported for work for a period of 5 consecutive business days without the consent of the employer, whichever occurs earlier. The employer should provide the student's name, SEVIS ID (if available), and the date the student's employment ended.
