The STEM OPT extension is a 24 month extension of your post-completion OPT for certain students with qualifying majors and employment opportunities.

STEM OPT Eligibility

  • Must be on active post-completion OPT.
  • Must have completed a degree in the United States in a qualifying STEM field.pdf (Science, Technology, Engineering and Mathematics)
  • Must have active or have an offer of paid employment directly related to the STEM degree with an employer that uses E-Verify to confirm employment eligibility. The employer must also have an EIN number, and agree to certain requirements listed on the I-983 Training Plan. Self-employment is not appropriate for the STEM OPT extension.
  • Employment through staffing agencies may not be suitable for the STEM OPT extension.  USCIS states, "Staffing and temporary agencies and consulting firms may seek to employ students under the STEM OPT program, but only if they will be the entity that provides the practical training experience to the student and they have and maintain a bona fide employer-employee relationship with the student".  This means your training and supervision must be provided by the employer completing your I-983, and cannot be delegated to the client or customer of the staffing agency. See  USCIS STEM OPT Employer Requirements and Responsibilities.
  • UConn is not an E-Verify employer. You may not work for UConn while on an active OPT STEM Extension.
  • You may be approved for up to two STEM OPT extensions per lifetime. Each extension must be based on a separate period of post-completion OPT, and the second STEM OPT extension must be based on a higher earned degree level than the first STEM OPT extension.
  • Most students apply for an OPT STEM Extension based on the degree their current OPT is based upon. However, you may apply for a STEM OPT extension based on a past STEM degree in certain circumstances (check with your ISSS advisor).
  • You may accrue up to 150 days of unemployment during the STEM OPT Extension, but this includes any unemployment days already accrued during the standard post-completion OPT period.

When to Apply

USCIS will receive your application up to 90 days before your current post-completion OPT end date. Your application must be received within 60 days of the ISSS STEM OPT Recommendation. If your application is timely filed, yet pending approval when your current OPT expires, you may work for the STEM extension qualifying employer for up to 180 days while awaiting your new EAD.

If your STEM OPT Extension will begin in October, select Fall term. If your STEM OPT Extension will begin in January, select Spring term.)

After reviewing the OPT Application, ISSS will return to you the following:

1) Updated Form I-20 with STEM OPT recommendation and STEM employer information on page 2

2) Form I-765 with any suggested revisions.

3) Instructions on what and where to send your STEM OPT application packet.

Documents to prepare for USCIS Application:

  • Form G-1145, if you want to receive email/text message application status updates.
  • Two recent color passport style photographs (write name and SEVIS ID number softly in pencil or felt pen on back of photos). See I-765 Filing Instructions for further photo details.
  • $410.00 USCIS Filing Fee. This can be paid by personal check, bank check or money order made out to U.S. Department of Homeland Security.  While it is possible to pay by credit card, we do not recommend that students do this.
  • Completed Form I-765, typed and printed and signed in blue ink.  
  • Photocopy of the new Form I-20 with STEM OPT recommendation on page 2. Sign the bottom of your form before making a photocopy.
  • Photocopy of all previous Forms I-20 (all pages). Include Forms I-20 received from other schools, if applicable.
  • Print out of most recent I-94 admission record OR photocopy of I-94 card (front and back) if you have a paper I-94 attached to your passport OR I-797 approval notice with attached I-94 (if you changed status to F-1 within the U.S.).

  • Photocopy of your diploma or transcript showing earned STEM degree.
  • List of all employers and dates of employment during your 12-month standard OPT period.

Step 4: After You File Application with USCIS

Receive I-797 (Receipt Notice)

Several weeks after receiving your application, USCIS will send you a Receipt Notice (I-797). This will list the Service Center where your application is being processed, the date your application was officially received, and a case number assigned to your application. Carefully review the notice to make sure your name is spelled correctly and the correct mailing address is listed.  If it is not, call the National Customer Service Center (NCSC) number listed on your receipt notice immediately.

Receive I-797 (Approval Notice)

After processing your OPT application, USCIS will mail you an approval notice (I-797).  This is a notification on your application status, NOT your work authorization/permission.

Receive an Employment Authorization Document (EAD)

You will receive an EAD separately in the mail from USCIS. This is your proof of employment authorization. You may not start working until you receive your EAD and the start date becomes effective. EADs cannot be forwarded by the post office, so if you move or change your mailing address you MUST notify USCIS with the updated address for EAD mailing.

For Employers

By employing an F-1 student visa holder with an OPT STEM Extension, you are providing a valuable training opportunity for the student to enhance their degree learning, and you will benefit from the skills, perspective and cultural competence they will bring to your organization. As the STEM OPT employer you do not need to file any government petitions or pay any visa related fees. However, you are responsible to complete and adhere to an individualized training plan for your STEM OPT employee. STEM OPT Employers agree to report to the Designated School Official any termination or departure of your employee within 5 days of the occurrence. To report the departure of your UConn STEM employee, please email

While completing the I-983 training plan with your employee, you may find it helpful to refer to the government’s Instructions for Completing Form I-983. ISSS may not provide you with any specific information regarding your employee or their visa status. Please refer to the resources below for further information on the STEM OPT Extension.

If your employee’s STEM OPT extension is not approved by the date their current OPT expires, and your employee had a timely filed STEM OPT Extension, they may continue to work for up to 180 days on the expired EAD while awaiting the STEM OPT EAD. For guidance on how to complete the I-9 in this situation, see the I-9 Manual for Employers 7.4.4. F-1 STEM OPT Extension.
