24-Month STEM Extension

F-1 students with STEM (Science, Technology, Engineering, Mathematics) degrees in fields listed on the ICE STEM Designated Degree Program List may be eligible for the 24-Month OPT STEM Extension. It allows you to continue working off-campus in a job related to your major directly after the completion of Post-Completion OPT.

• You must be currently authorized for Post-Completion OPT (or you are on the "Cap Gap Extension").
• You must have received a bachelor’s, master’s or doctoral degree from a SEVIS certified U.S. school in a field on the ICE STEM Designated Degree Program list.  Only degrees received within 10 years of the date of your DSO recommendation for an OPT STEM Extension are eligible.
• You may use a degree received from a U.S. school other than the University at Buffalo, provided that you meet all of the requirements listed in this section.
• You must have a job or a job offer from an employer that meets all of the requirements explained below:  
  • The employer must be registered in the E-Verify system. E-Verify is an Internet-based system operated by the Department of Homeland Security (DHS) in partnership with the Social Security Administration (SSA).  It allows participating employers to electronically verify the employment eligibility of their newly hired employees. 
  • Your employment must be directly related to your field of study. It is your responsibility to prove and document how your employment is directly realated to your field of study. 
  • You must work at least 20 hours per week.
  • You must be paid. Volunteer employment is not permitted.
  • You cannot be self-employed.
  • The employer must agree to sign and adhere to the training program outlined in Form I-983.
• Each student is permitted a lifetime maximum of two OPT STEM extensions.  To qualify for a second OPT STEM Extension, your second STEM eligible degree must be at a higher level than your first STEM eligible degree and you must have a valid Post-Completion OPT EAD card. 
• We recommend that both students and employers review the 24-Month OPT STEM information found on the Department of Homeland Security’s Study in the States website for information on employer responsibilities and other requirements.

The earliest you can apply for the 24-month OPT STEM Extension is 90 days prior to the expiration of your EAD card.  If it is submitted too early, the USCIS will deny the application. 

Your application must be received by the USCIS before your current OPT EAD card expires.

  • Please review these photo specifications. If your photos do not meet USCIS requirements exactly, your application may be rejected or denied.
  • In pencil, please write your name and I-94 number lightly on the back of each photo.

The address to use depends on the mailing address listed on your I-765. Please refer to the USCIS' lockbox page for details.

You should use a reliable, express delivery service (e.g. UPS, FedEx) to mail your application. Utilizing an express delivery service will enable you to track your application and its delivery. Please save your receipt.

ISS recommends that you use a mailing address on your Form I-765 where you can receive mail for 3-5 months after applying for OPT. However, if your mailing address changes after you submit your OPT application to USCIS, you must notify the USCIS, the Post Office and ISS of your change in address within 10 days of the change. Failure to notify USCIS and the Post Office in a timely manner could result in delays in receiving your EAD.

To notify the USCIS, use their online Change of Address Form. You will need your OPT Application Receipt Number to complete the form. If you move to a new address, you should also notify the US Postal Service (USPS) using their online form.  Finally, to notify ISS, follow the instructions found at the bottom of this page.

Currently, processing time at the USCIS can be as long as 5 months. However, processing times vary widely, depending on the time of year and workload at the Service Center to which you send your application. We encourage you to regularly review the processing times found on the USCIS website.

If you have a job offer and 120 days has passed since the Receipt Date on your I797 Receipt Notice, you may contact us for assistance. We can inquire with USCIS about the status of your application. However, we cannot guarantee that our inquiry will result in an expedite or change in processing times.

Once you have waited 150 days, or beyond the current maximum published USCIS processing times, we recommend that you take the following actions:

• Email ISS with a copy of your receipt notice and a description of the actions you have already taken (any communication with USCIS, for example). If ISS has not already inquired with USCIS on your behalf, we will do so.
• File an "Outside Normal Processing Time E-Request" with USCIS.
• File a Case Assistance Request with the CIS Ombudsman Office. You can find additional information about the role of the CIS Ombudsman and how to file a request for assistance here.

USCIS expedite criteria are very strict and it can be difficult to provide sufficient evidence to meet the USCIS criteria. Having a job offer or the possibility of losing that job do not generally qualify for an expedite unless you can effectively make an argument that your situation does meet the criteria. If considering an expedite, please ensure that you have sufficient documentation and a compelling argument.

Additional information on expedite criteria and how to file can be found on the USCIS page. 

 If you submitted your complete application to the USCIS in a timely manner (i.e. before your EAD card expired), then you may continue working for up to 180 days while your application is pending with the USCIS. However, if your application is denied by the USCIS, you must stop working upon the date of denial or risk accruing unlawful presence.

It is possible to change employment while your application is pending with the USCIS. However, you are required to report any change of employment to ISS and to the USCIS.  ISS must issue you a new I-20 reflecting your new employment information.  Your new employer must meet all USCIS criteria for a STEM Extension employer and you must submit a new Form I-983 and Final Evaluation for your previous employment, to ISS.    

Contact ISS for instructions on how to report your new employment to the USCIS. 

If your Post-Completion EAD has expired, we do not recommend traveling outside the U.S. until after your 24-Month OPT STEM Extension application is approved and you have your new EAD card.

For additional, general OPT travel information visit our Travel While on OPT page.  

It is imperative that you read, understand, and adhere to OPT STEM requirements. Failure to do so could result in the denial of future immigration benefits.

If you maintained your immigration status during your 24-Month OPT STEM Extension, you will have a 60-day grace period after your EAD expires.  You are permitted to remain inside the U.S. during those 60 days to prepare for your departure, apply to change your status (if eligible) or begin a new degree program.  If you are not admitted to a new degree program or do not submit a change-of-status application before the end of the 60 days, you must leave the U.S.

• If you transfer to another school or begin study at another educational level at UB, then your OPT authorization will automatically be terminated.  
• If you are accepted to begin another degree program at UB and your OPT has not yet expired, your OPT will terminate on the first day of classes for your new degree program.
• If you later decide not to mail your 24-Month OPT STEM Extension application to USCIS for any reason, you must notify ISS immediately so that we can cancel your OPT recommendation in SEVIS.
• While on OPT, you are still in F-1 status.
