Optional Practical Training (OPT) allows F-1 students to work in the United States in a job directly related to their field of study. USCIS grants up to 12 months of OPT authorization, with a potential 24-month extension for graduates in STEM fields. The application process involves both your Designated School Official (DSO) and USCIS, and missing key deadlines can end your work authorization before it begins.
What Is OPT and Who Qualifies
OPT is authorized under 8 CFR 214.2(f)(10) and is available to F-1 students who have been enrolled full-time for at least one full academic year. There are two types: pre-completion OPT, which you can use before graduation, and post-completion OPT, which begins after you finish your degree. Most students apply for post-completion OPT, as it provides a full 12 months of work authorization following graduation.
To be eligible, you must be in valid F-1 status at the time of application. Students who have already used 12 months of pre-completion OPT will have that time deducted from their post-completion OPT allotment. If you used 6 months of pre-completion OPT, for example, you would only receive 6 months of post-completion OPT. Each degree level - bachelor’s, master’s, doctorate - comes with its own 12-month OPT period, meaning a student who completes both a master’s and a doctorate can apply for separate OPT periods for each.
Students applying for STEM OPT extension must have a degree in a field listed on the official DHS STEM Designated Degree Program List and must be employed by an employer enrolled in the E-Verify program. The extension application is filed on Form I-765, the same form used for initial OPT, and must be submitted while the initial OPT EAD is still valid. USCIS allows the STEM extension application to be filed up to 90 days before the initial OPT period ends.
Your DSO plays a central role throughout. They must update your SEVIS record and issue a new Form I-20 with an OPT recommendation before you can file with USCIS. Without that updated I-20, USCIS will reject your application outright.
Filing Form I-765: Timing Is Everything
The application for OPT is filed using Form I-765, Application for Employment Authorization. The filing fee is $410, though USCIS periodically adjusts fees, so verify the current amount at uscis.gov before submitting. You must file by mail to the designated USCIS lockbox facility listed in the form instructions - online filing is not currently available for OPT applications.
For post-completion OPT, USCIS rules establish a firm filing window. You may file Form I-765 no earlier than 90 days before your program end date and no later than 60 days after your program end date. Your DSO must have entered the OPT recommendation in SEVIS before you mail the application. If you file outside this window, USCIS will reject the application regardless of how complete and accurate it otherwise is.
The OPT start date matters and requires careful planning. You select your requested OPT start date on Form I-765, and it must fall within 60 days after your program end date. USCIS will not approve a start date earlier than the date the application is received. Standard processing for Form I-765 currently averages between 3 and 5 months, though this fluctuates. Because you cannot begin working until you receive your Employment Authorization Document (EAD), most students select a start date several months out to account for processing time, then confirm through USCIS’s case status tool whether premium processing is available - it is not available for initial OPT.
Once USCIS approves your OPT, you receive an EAD card that lists your authorized start and end dates. You must begin working within 90 days of the OPT start date listed on your EAD, or USCIS may consider you to have violated your F-1 status. For STEM OPT students, you also have a 150-day unemployment limit across the full 24-month extension period.
Your I-94 record and F-1 visa stamp do not need to be current for you to work on OPT inside the United States, but if you travel internationally after your visa expires, you will need a new F-1 visa stamp to re-enter. Plan international travel carefully during your OPT period.
Common Reasons USCIS Rejects OPT Applications
USCIS rejects a significant portion of OPT applications due to avoidable errors. Understanding the most frequent rejection reasons can save months of delays and potential status violations.
Filing outside the application window is among the most common problems. Students who mail their application even one day before the 90-day opening or more than 60 days after their program end date will receive a rejection. USCIS does not grant exceptions for mailing delays or clerical mistakes. The date USCIS receives the package - not the date you mailed it - is what counts.
Mismatched information between Form I-765 and your SEVIS record or I-20 causes frequent rejections. Your name, date of birth, SEVIS number, and program end date must all match exactly. A middle name present in SEVIS but omitted from the form is sufficient grounds for rejection. Review every field carefully before submission.
Missing or incorrect supporting documents also lead to rejections. For initial post-completion OPT, USCIS requires the completed Form I-765 with your signature, the filing fee, a copy of your I-94, a copy of your current and all previous F-1 visas, a copy of your current I-20 with the DSO’s OPT recommendation signature, copies of all previous I-20s, two passport-style photos, and a copy of your passport biographical page. Omitting any of these - particularly old I-20s - results in rejection.
Filing before the DSO has updated SEVIS is another straightforward mistake. If your DSO has not yet entered the OPT recommendation in SEVIS, your I-20 will not reflect the correct dates and status. USCIS verifies SEVIS records directly. Do not mail your application until your DSO confirms the SEVIS update is complete and has provided you with the updated I-20.
Incorrect OPT start date selection creates problems that cannot easily be corrected after the fact. The requested start date cannot be more than 60 days after your program end date, and USCIS will not approve a start date earlier than the receipt date of your application. Students who request a start date that has already passed when USCIS adjudicates the case may have the start date automatically shifted, shortening the total OPT period.
What to Do If Your Application Is Rejected or Denied
A rejection differs from a denial. USCIS rejects applications for procedural issues - missing documents, wrong fee, filing outside the window - and returns the package. A denial occurs after USCIS reviews a complete application and concludes you do not qualify. Rejections can generally be corrected and refiled if the application window is still open. Denials require a more formal response, including a Motion to Reopen or Reconsider on Form I-290B, or in some cases an appeal.
If your application is rejected and the filing window has closed, consult an immigration attorney immediately. Some students in this situation apply for a change of status or explore whether a cap-gap extension applies to their circumstances. The cap-gap rule, established under 8 CFR 214.2(f)(5)(vi), automatically extends the F-1 status and OPT of students who have a timely filed H-1B petition for the following fiscal year, bridging the gap between OPT expiration on April 30 and the H-1B start date of October 1.
