OPT STEM Extension

Bridge from Student to Employee
UPDATE! The Department of Homeland Security just announced the new STEM OPT rule, which became effective on May 10, 2016. The new rule permits up to two STEM extensions of 24 months each, replacing the old rule which only allowed STEM extensions of 17 months. Just as with the old rule, the new rule authorizes STEM OPT extensions only for students employed by employers who participate in E-Verify, but also still allows those employers subject to the higher education E-Verify limitation to offer employment to students seeking the STEM extension. The new rule introduces compliance requirements for employers who hire STEM OPT workers, including Form I-983, which will document a formal training plan for the STEM employee. Employers will also be required to evaluate student progress annually, attest that the STEM OPT worker is not replacing a U.S. worker, and that the STEM student's compensation will be commensurate with that of other similarly employed workers. A copy of the new final rule is available here. For a detailed summary and additional resources, please click here.

F-1 students who are currently authorized for OPT employment based on completion of a Bachelor’s, Master’s or Ph.D. degree in a Science, Technology, Engineering or Math (STEM) field, as defined by DHS, may be eligible for a 24-month extension of OPT.

Eligibility Requirements for the 24-Month STEM Extension

  • 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 24-month STEM OPT extension.
  • Student has had fewer than 90 days of unemployment while on OPT.
  • Student is employed by or has a job-offer from an employer registered with the "E-Verify" employment verification system.

There is a lifetime limit of two periods of 24-month STEM OPT; each occurring after a higher degree level has been obtained.  A STEM degree obtained at a U.S. university prior to your current degree may be the basis for a STEM extension under certain circumstances.

Prior Degree

To use a prior degree to qualify for the STEM OPT extension, the F- 1 student must:

  • Most recent degree (need not to be STEM) from an accredited SEVP certified school.
  • Have received their prior, qualifying STEM degree (at the bachelor’s level or higher) within 10 years preceding the date of application for the STEM OPT extension with USCIS.
  • The qualifying STEM degree needs to be on DHS’s STEM List at the time the student submits their application for 24-months extension

When to Apply

A qualifying STEM degree holder may file the 24-month extension application within the 90 days before the current OPT end date. However, the STEM extension application must be received by USCIS within 60 days of the date on which UW-Platteville issues the new I-20 recommending the 24-month extension. In general, a 24-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 24-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.

How to Apply

Please see the documents listed in the "Instructions" box at the right.


Under STEM OPT Extension, students are allowed an additional 60 days of unemployment after their OPT ends, for a total of 150 days of allowable unemployment (90 days during the initial period of post-completion OPT plus an additional 60 days during the extension period).

Employer's Responsibility

  1. Complete and Certify the Form I-983. The STEM OPT program requires employers to submit and certify a mentoring and training plan (Form I-983) for the STEM OPT student they hire.
  2. Review student's annual self-evaluation of their own progress and sign it to attest to its accuracy. The student must submit the first assessment within 12 months of the OPT STEM start date, and a second, final assessment that recaps the training and knowledge acquired during the complete training period. The evaluation must have an applicable date range associated with it, so the relevant timeline for the evaluation is clear. The student submits the 12-month and final evaluations no later than 10 days following the conclusion of the applicable reporting period. The employer’s Official with Signature Authority from the Form I-983 must print, sign and enter the date of the signature to show concurrence with the assessment information that the student entered. Once signed, the employer must return the evaluation to the student, who will provide it to their DSO for recordkeeping.
  3. Report material changes to an existing Form I-983 (i.e. change in EIN, reduction in student compensation that is not tied to a reduction in hours worked, any significant decrease in hours per week that a student engages in a STEM training opportunity, changes to the employer's commitments or student's learning objectives as documented on Form I-983). So long as the STEM OPT student and employer meet the regulatory requirements, and the modified Form I-983 meets the specified requirements, the student’s employment authorization will not cease based on a change to the plan.
  4. Report student loss of employment. 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 ( 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.
  5. Employment must be paid and would be subject to wage protection.
