STEM: Optional Practical Training Extension

STEM OPT Extension

The STEM OPT Extension is a 24-month extension of work authorization available to international students who are currently engaged in Optional Practical Training (OPT) and who have earned a qualifying degree in a science, technology, engineering, or math (STEM) field. Students require a STEM OPT I-20 from ISSS as part of their application to U.S. Citizenship and Immigration Services (USCIS).

How to Apply for STEM OPT

Follow the steps below:

  1. Begin by completing an I-983 with your employer and emailing it to Then, visit our STEM OPT Request and Reporting form to request your new STEM OPT I-20. The I-983 requires information from both the student and the employer. For assistance in completing this form, please view our Guide to Completing the I-983.
  2. ISSS will prepare a new I-20 for you. In most cases your I-20 will be ready in one week. We will notify you via email once it is ready.
  3. After receiving your new I-20, you must submit an application packet to USCIS. Refer to page 3 of the Optional Practical Training: STEM Extensions packet for a checklist. Mail the documentation on the Checklist to USCIS. Keep in the mind following:
    • The earliest date to apply is 90 days before OPT end date (ISSS will not process your request before this date).
    • USCIS must receive your application within 30 days after the OPT I-20 is issued.
    • USCIS must receive your application before the expiration date of your Employment Authorization Document (EAD).


We recommend using a trackable mail service such as FedEx or United Parcel Service (UPS). The address you use on the I-765 determines where you should send your application (see USCIS I-765 mailing instructions).


Start planning for your STEM OPT application before your current EAD card expires. After that expiration date, you are no longer eligible to apply for STEM extension. See step 3 above for specific timelines required by USCIS.  

These deadlines refer to when the USCIS will receive their application, so students should allow time for working with ISSS on the application and mailing it in.


Is my degree eligible for a STEM extension?
A student must have earned a bachelor’s or higher degree on the STEM Designated Degree Programs* list within the last 10 years. To check if your major is eligible, look at the “Primary Major” on your I-20, then search for that code in the CIP code column on this list.

Do I need a job offer to apply for STEM OPT?
Yes, you must already have an employer to fill out an I-983.

How do I choose my start date? What should my end date be?
The start date of the 24-month OPT extension will be the day after the end date on your OPT EAD card and the end date will be 24 months later. For example, if my USCIS authorized OPT end date is 06/02/2018, then my STEM start date is 06/03/2018 and the end date will be 06/02/2020. These dates are not flexible.

Where can STEM OPT students work?
Anywhere in the US for an E-Verify employer in a paid position directly related to his or her major.  A student authorized for a 24-month extension must work at least 20 hours per week.

What happens after I submit my application?
Approximately 2-3 weeks after USCIS receives your application, they will mail a receipt notice to the address listed on your I-765. The receipt includes a tracking number to check the progress of your STEM OPT application online. Your card should arrive to the address listed on your I-765 approximately 3-5 months after USCIS receives your application. If your OPT extension is approved, you must send a photocopy of your new EAD card to the ISSS at

What if my STEM extension is still pending after my OPT end date?
If you have timely filed the application for the STEM extension, you may continue working even if your EAD card has expired and until your OPT extension is processed or until 180 days has passed, whichever is sooner.

What is the unemployment limit on STEM OPT?
You are allowed a maximum of 150 days of unemployment time, which includes any unemployment accrued during 12-month OPT.

How do I report changes in my employment status, or my personal contact information?
You are required to report any of the following through the STEM OPT Request & Reporting form within 10 days:

  • Starting a new job (send an updated I-983 to
  • 12-month or final evaluation reports (send an updated I-983 to

You are also required to report any of the following changes through the SEVP Portal within 10 days:

  • Your legal name or contact information (phone number, mailing address)
  • Your employment address/location

You should also share the Study in the States: STEM OPT Hub, a USCIS website designed to help students and employers navigate STEM OPT.

Yes, students may work for more than one employer, but all employment must be related to student's degree program and all employers must be enrolled in E-Verify.

Yes, students may take a position where they perform a service based on a contractual relationship rather than an employment relationship. The company must be registered with E-Verify. If requested by DHS, students must be prepared to provide evidence showing the duration of the contract periods and the name and address of the contracting company.

Technically, no.  Under the regulations, students may not fill out their own Form I-983, Sections 3 to 6, nor act as their own employer for the purposes of the form. Therefore, self-employment is not acceptable for the purposes of STEM OPT employment.

A student can apply for STEM OPT once per degree level (i.e., bachelor's, master's or doctorate) for a maximum of two STEM OPT periods.

To participate twice in the STEM OPT extension, a student must earn a second qualifying degree at a higher education level and must be participating in active post-completion OPT at the time they apply to USCIS for their second STEM OPT extension. In some cases, students may be eligible to use a prior STEM degree to qualify for their second STEM OPT extension.

You must complete a new I-983 with your new employer and submit it to our office. You must also report this change through our STEM OPT Request form by selecting this option: My STEM extension is pending. I have changed employers and am providing updated employment details. Once you have completed this process, our office will report the change to the USCIS.
