Employers’ STEM OPT Responsibilities

If you are an employer who wants to hire an international student for the STEM OPT extension you must:

  • Be enrolled in the E-Verify program and remain in good standing.
  • Provide an employment opportunity that is commensurate with those of similarly situated U.S. workers in duties, hours, and compensation
  • Document and provide a formal training program to augment the student’s academic learning through practical experience.
  • Complete the Form I-983, Training Plan. In this form, you must attest that:
    • You have enough resources and trained personnel available to appropriately train the student;
    • The student will not replace a full- or part-time, temporary or permanent U.S. worker; and
    • Working for you will help the student attain their training objectives.
  • Report material changes to the student’s employment to the DSO within 5 business days.

The United States Immigration and Customs Enforcement (ICE) may visit your worksite(s) to verify whether you are meeting the STEM OPT program requirements, including whether you are maintaining the ability and resources to provide structured and guided work-based learning experiences for the student.


Maintaining F-1 Status during the OPT STEM OPT Extension


You are required to report the following information to the Slater International Center throughout the entire period of your STEM OPT extension:

  • Your legal name
  • Your residential or mailing address
  • Your email address
  • Your employer’s name
  • Your employer’s address

You must report any change in this information to the Slater International Center within 5 business days of the change.  Failure to report properly could be considered a violation of your F-1 student immigration status and could result in the termination of your SEVIS record.

It is your responsibility to follow these reporting requirements but the Slater will send reminder emails with a form to update every six months to verify your contact and employment information. Please complete the form and return it to the Slater International Center within 5 business days.

Evaluation Reporting

You must also complete two self-evaluations. These evaluations are found on page 5 of the Form I-983.  The first evaluation must be submitted within 12 months of the STEM OPT start date.  The second evaluation must be submitted at the end of the STEM OPT period.  You and your immediate supervisor must sign the evaluation and submit it to the Slater International Center.

Changing Employers while on STEM OPT

If you leave your current place of employment while on STEM OPT, you must let the Slater International Center know within 5 days of ending employment and complete the “Final Evaluation on Student Progress” on page 5 of the Form I-983 and submit it via the STEM OPT Validation Report.

If you begin new employment, you must also submit a new Form I-983 with your new employer information and training plan. Please submit the new Form I-983 via the STEM OPT Validation Report prior to beginning your employment. A Slater International Center staff member will review your training plan and if it is complete, issue you a new Form I-20 with your new employer information. You may not begin employment until your Form I-983 has been reviewed and approved.


For STEM OPT, you are granted an additional 60 days of unemployment for a total of 150 days of unemployment for the duration of your OPT. Please let the Slater International Center know if you are approaching 150 days of unemployment so we may assist you in maintaining your status.


Travel and Re-Entry to the United States

You must have a valid travel signature on your Form I-20 to travel and re-enter the United States in F-1 status. (while on STEM OPT the travel signature is valid for 6 months)

Documents Required to Re-Enter the U.S. While on STEM OPT:

  • A valid F-1 visa
    If your F-1 visa has expired and you must travel outside of the U.S., you will need to apply for a new visa at a U.S. Consulate outside of the U.S. You may remain in the U.S. with an expired visa as long as your EAD, Form I-20, and passport are valid.
  • A valid passport (must be valid at least six months into the future.)
  • A valid EAD – While the EAD is marked, “Not valid for re-entry,” this simply means that the card alone is not sufficient for re-entering the U.S.
  • Form I-20 with STEM OPT showing "Approved" and a travel signature less than 6 months old
  • Proof of employment – A letter from your current or prospective employer which indicates that you have a temporary job offer and that you will be employed.

Note: If you re-enter the U.S. in visa waiver or tourist status during your OPT authorized period, you are no longer eligible for STEM OPT.
