OPT STEM Extension

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

If you would like your STEM OPT participation to be based on a previously‐obtained STEM degree, and not on the degree upon which your current post‐completion OPT was granted, you will need to check “yes” to the question on Form I-983 that asks if your STEM OPT extension is “Based on 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 and Reporting Requirements

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 (isss@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.
  5. Employment must be paid and would be subject to wage protection.

What is a Principal Designated School Official (PDSO)?

At schools authorized to receive international students, one or more Designated School Officials (DSOs) are chosen by the school as official representatives to the U.S. government and authorized by the government to issue F-1 class non-immigrant student visa-related documents. Each government-approved school must choose one PDSO who will be responsible for all the DSOs at the school, who will maintain the official government records for international students, and who is authorized to make changes in the DSO team.

What is a Responsible Officer (RO)?

All government-approved J-1 exchange visitor program sponsors appoint an RO to administer the program according to the regulations and to represent the sponsor to the U.S. government. Program administration refers to the daily operation of the program and includes selecting participants, providing pre-arrival and orientation information to participants, issuing Form DS-2019, overseeing the general activities of the participants, communicating with the U.S. Department of State, and maintaining records on the program.
