STEM Extension Information




On February 26, 2021, USCIS announced flexibilities for certain foreign students affected by the delays in receipting OPT/STEM applications. 

Note: these flexibilities apply only to applications received on or after Oct. 1, 2020, through May 1, 2021, inclusive.

1. If your application was rejected, USCIS will accept a refiled Form I-765 for OPT and STEM OPT as filed on the original filing date if:

  • The original, timely filed application was received on or after Oct. 1, 2020, through May 1, 2021, inclusive; and
  • USCIS subsequently rejected it.

Refiled applications must be received by May 31, 2021, for USCIS to treat the application as though filed on the original received date. Do NOT refile if your application was not rejected.

2. Applications with missing or deficient signatures will continue to be rejected at the lockbox.  However, if an application with a with missing or deficient signatures is receipted, the application will not be denied but instead receive an RFE to give applicants am opportunity to correct the deficiency.

For more information, please visit the USCIS Alerts Page.

If you have not heard from USCIS:

US Citizenship and Immigration Services (USCIS) is experiencing significant delays with receipting OPT/STEM OPT applications nationwide. The processing delays are affecting all OPT and OPT STEM applications. Delays of up to 8-9 weeks are now common.  If you have filed your application on time, you may legally stay in the U.S. until your application has been adjudicated.

We recommend all applicants who have not received a receipt notice within 60 days of filing to follow the steps below:

  1. Retain all evidence that you filed your application in a timely manner as well as proof of delivery.  You should also keep a copy of any communications you have sent to USCIS.
  2. Check with your bank/financial institution to see if funding has been processed by USCIS.
  3. Contact USCIS. Check to see your application status and if they can provide you a receipt number.  There are times when the application has been receipted but the notice has not yet been sent out.
  4. E-mail the USCIS “lockbox” at [email protected]
  5. If USCIS does not respond to your inquiry within 30 days, you may submit a request for case assistance to the CIS Ombudsman.

*The ISO does not recommend refiling a new application if there are no errors with your original application.  Doing so may cause further delays and result in students being possibly charged twice for the filing fee. *

If it has been more than 6-weeks since your application arrived at USCIS and your case still has not been receipted, you can e-mail the USCIS “lockbox” (they process the incoming applications) at [email protected].

Please reach out to the ISO at [email protected] for any additional inquiries/concerns you may have.

Students who hold degrees in STEM fields (Science, Technology, Engineering, and Mathematics) may be eligible to apply for a 24-month extension of Optional Practical Training (OPT), in addition to their 12-month Post-Completion OPT.

Non-STEM field students do not qualify to apply for the extension. It is possible, however, to use a prior U.S degree to apply for the extension if the degree was in a STEM field and was conferred within the last 10 years.

Please check the Designated STEM Degree Program List to see if your degree qualifies you for a STEM OPT extension. If you are not sure, please contact your ISO Advisor.

Sending Your Application to USCIS

On 4/12/2021, U.S. Citizenship and Immigration Services (USCIS) announced that F-1 students seeking Optional Practical Training (OPT) can now file their form I-765 online if filling under the pre-completion, post-completion and the 24-month STEM extension categories.

It is extremely important to proceed carefully with the online application process. The system allows you to submit your application without all required documents and this may result in complications with your online application.

Otherwise, you may continue to submit the OPT application to USCIS by mail. Please consult with an ISO advisor if you are unsure about the process.

Students are eligible for the Cap-Gap extension if:

The employer files the H-1B petition and it is received by USCIS prior to the end of the post-completion OPT. In this case, a student’s employment authorization is extended until September 30th.

The employer files the H-1B petition and it is received by USCIS after the end of post-completion OPT but during your 60 day grace period following OPT. In this case, the student is allowed to remain in the US but not authorized to work until the H-1B goes into effect on October 1st.

Note: If the H-1B is not approved by Sept 30, the F-1 employment authorization will end. A student will have the standard 60-day grace period from the Cap Gap end date of Sept 30.
