STEM Extension OPT


Students applying for F-1 Optional Practical Training (OPT) and STEM Extension OPT may file Form I-765 online or via regular post. You should NOT mail your documents to USCIS if you choose to file online. If you choose to mail in your OPT application to USCIS, you can find the filing address for the USCIS Chicago Lockbox Facility on the USCIS website at If you choose to file online, here are some things to consider:

  • Students must still obtain an OPT-endorsed I-20 or STEM OPT-endorsed I-20 from the Office of International Affairs before filing Form I-765
  • Students must be within the United States when filing their OPT application online
  • USCIS may require you to appear for an interview or provide biometrics (fingerprints, photograph, and/or signature) at any time before making a decision on your application
  • USCIS must still receive your OPT application within 30 days of the OPT-endorsed I-20 issuance date
  • You must upload a passport-style photograph (2 inches by 2 inches) of you must  be uploaded in JPG, JPEG or PNG file formats
  • Other files such as I-20 copies, passports and/or previous EAD must be uploaded in JPG, JPEG, PDF, TIF, or TIFF file formats (max size: 6 MB per file)
  • Foreign language documents must have an English translation
  • All uploaded files must have titles in English and no special characters (#, ?, etc.)
  • Do not enter “N/A” for non-applicable fields on the online application
  • The application will be submitted once the non-refundable $470 payment has been made. If you would like a student immigration coordinator to review your OPT application during a virtual appointment, please do not submit payment until we have reviewed your application

Eligibility for a second period of STEM OPT after higher degree

Example: If you receive a 24-month STEM OPT extension based on your bachelor's degree in computer science, and you later earn a master's degree in computer science or another STEM eligible field, you may apply for Post-Completion OPT and then the additional 24-month STEM OPT extension based on your master's degree.

Eligibility based on a previously obtained STEM degree

If you are currently in a degree field (or on Post-Completion OPT from that degree) that is not identified as STEM eligible but have previously earned a STEM-eligible degree from an accredited U.S. higher education institution, you may be eligible to apply for a STEM OPT extension under certain conditions:

Example: If you are currently participating in Post-Completion OPT based on a master's degree in business and management, but you previously received a bachelor's degree in mathematics, you may be able to apply for a STEM OPT extension based on your bachelor's degree in mathematics as long as you meet all the criteria above.

When to apply

Here are the basic steps of a STEM OPT application:

The application must be submitted to the Office of International Affairs no later than one week prior to the end of your current Post-Completion OPT. The STEM OPT application must be received by USCIS before the expiration of the current OPT period. However, you can submit an application to USCIS as early as 90 days prior to the end of the current OPT period.

If you timely file your STEM OPT extension application, you will be able to continue employment while your application is pending until a final decision is made by USCIS or for 180 days beyond the expiration of your Post-Completion OPT, whichever comes first. It normally takes up to 90 days for USCIS to process STEM OPT extension applications.
