About Optional Practical Training (OPT) STEM Extensions

The OPT STEM Extension is a work authorization extension granted by the Department of Homeland Security (DHS) through the United States Citizenship & Immigration Services (USCIS), which enables a student to continue working after their first year of OPT has ended.

Students who have earned a degree from an accredited and SEVIS approved U.S. Institution, either currently or previously, in a STEM field (Science, Technology, Engineering, or Mathematics) may qualify to apply for an extension of their OPT for an additional 24 months.  

Students must be employed by an E-verify company.  There must be an established employer-employee relationship between the employer and the F-1 student.

OPT STEM Extension Eligibility Requirements

In order to apply for OPT STEM Extension, students must meet the following requirements:

  • Must have graduated from a qualifying STEM program with a qualifying CIP Code

  • Must be currently authorized on post-completion OPT

  • Must have an E-Verify employer

  • Must be employed for a minimum of 20 hours per week

  • Must be employed in your major field of study

  • Must be receiving compensation for your work

When Students can Apply for an OPT STEM Extension

Students may apply for STEM OPT extension up to 90 days prior and no later than their current OPT expiration date. USCIS must receive your application by your OPT expiration date at the latest.

OPT STEM Extension Application Process

Updating Mailing Address while OPT is Pending

If you move while your OPT application is pending with USCIS and you did not give them a separate mailing address, you will need to update your mailing address with USCIS.

It is recommended that all OPT students also verify their address with USPS before updating USCIS.

Responsibilities and Maintaining F-1 Status while on OPT STEM Extension

After you receive your EAD card from USCIS, submit a copy of the card (front and back) through your International Student and Scholar Services Portal. This is necessary to check that there are no errors on the card. If either you or your international student advisor finds errors on the card, it will need to be mailed back to USCIS for correction. Please contact your international student advisor for this situation.

Within 10 days of any changes to the student’s address or employment (moving to a new address, starting a job, quitting a job, adding a second job, etc.), contact your international advisor.

OPT SEVP Portal

Since your OPT will have already been approved, you will not receive a new email to activate the SEVP OPT Portal. While this account will have been automatically generated for students on OPT, International Student and Scholar Services strongly recommends that students instead use the International Student and Scholar Services Portal to complete all employer reporting so that International Student and Scholar Services can better assist if there is a problem. 

Employment on OPT

EAD Card was not Delivered or was Lost by USPS

If the USCIS Case Tracker says that the EAD card was delivered but it is not in the mailbox, there are not a lot of options available.

International Student and Scholar Services recommends that students first contact their local USPS to file an inquiry.

If students are unable to find the EAD card, then it is recommended to contact ISSS for additional guidance to request a replacement EAD by filing a new Form I-765 online and paying a filing fee. If you did not receive an EAD that USCIS mailed, you can also submit an inquiry on non-delivery of a card.

Options After OPT STEM Has Ended

Just like with completing your degree program and first year of OPT, you will have a 60-day grace period after your OPT STEM extension has ended. You will need to choose to do one of the following:

  • Return to your home country before the end of your 60-day grace period,

  • Change your immigration status by filing an application with USCIS

  • Begin a new degree program (either at UNLV or another school)
