Optional Practical Training (OPT) gives F-1 students up to 12 months of work authorization in the United States directly related to their field of study. The application process runs through USCIS and requires careful attention to deadlines, paperwork, and eligibility conditions. Missing a single date or submitting an incorrect document can result in rejection, lost work time, or a gap in lawful status. Understanding how the process works before you begin is the most effective way to avoid those outcomes.
What OPT Is and Who Qualifies
OPT is a form of employment authorization for F-1 students that allows them to gain practical experience in their major field of study. It comes in two forms: pre-completion OPT, which students can use before finishing their degree, and post-completion OPT, which begins after graduation. Most students apply for post-completion OPT.
To be eligible, a student must have been enrolled full-time for at least one full academic year in a program at a SEVP-certified school. Part-time enrollment does not satisfy this requirement. Students who have previously used 12 months of full-time Curricular Practical Training (CPT) are ineligible for OPT, since 12 months of full-time CPT exhausts OPT eligibility entirely.
The employment must be directly related to the student’s major area of study. A biology graduate working as a lab technician qualifies; the same graduate working as a restaurant manager does not. USCIS does not pre-approve specific job offers during the OPT application process, but the student is responsible for ensuring any job taken during OPT meets this requirement.
Students in STEM-designated programs - science, technology, engineering, and mathematics - may apply for a 24-month STEM OPT extension after their initial 12-month OPT period. This extension requires working for an E-Verify employer and submitting Form I-983, the Training Plan for STEM OPT Students, to the student’s Designated School Official (DSO).
Application Timing: The Window Is Narrow
The OPT application timeline is one of the most common sources of errors. USCIS allows students to apply for post-completion OPT up to 90 days before their program end date and no later than 60 days after that date. This creates a 150-day window, but the boundaries are strict.
The student’s DSO must first enter a recommendation for OPT in the Student and Exchange Visitor Information System (SEVIS) and issue an updated Form I-20 with an OPT recommendation. The student then files Form I-765, Application for Employment Authorization, along with the required supporting documents. USCIS must receive the application within 30 days of the DSO’s SEVIS recommendation date - this is a separate and often overlooked deadline.
If the application is filed too early (more than 90 days before the program end date), USCIS will reject it. If it is filed too late (more than 60 days after the program end date), the student will have fallen out of F-1 status and will no longer be eligible. USCIS does not make exceptions for applications that miss these windows due to postal delays or administrative errors.
USCIS processing times for Form I-765 have historically ranged from three to five months, though times fluctuate. Students should check the USCIS processing times page for the most current estimates. Because of this delay, students who want to begin working immediately after graduation should file as early as possible within the 90-day window. The Employment Authorization Document (EAD) cannot be issued with a start date earlier than the program end date, so filing early does not accelerate the actual work start date - it simply reduces the risk of a gap.
The requested start date on Form I-765 matters. The student selects this date, and it cannot be changed after filing. If the start date is set too far in the future, the student loses authorized work time. If the requested start date has already passed by the time USCIS approves the application, USCIS will use the approval date as the start date instead.
Common Reasons OPT Applications Are Rejected
USCIS rejects OPT applications for both technical and substantive reasons. Understanding the most frequent causes gives applicants a clear checklist before submitting.
Incorrect or missing Form I-20. The I-20 submitted with the application must include the DSO’s OPT recommendation and must be signed by both the DSO and the student within the past 30 days. Submitting an outdated or unsigned I-20 is one of the most frequent rejection triggers.
Wrong fee or missing fee. As of 2024, the filing fee for Form I-765 is $410 for paper filings. Fee amounts can change, and USCIS will reject any application with an incorrect payment. Students should verify the current fee on the USCIS website immediately before filing, since published guides and university handouts can become outdated.
Passport validity issues. USCIS requires that the student’s passport be valid for at least six months beyond the OPT start date. A passport that expires before that threshold will cause the application to be rejected or the EAD to be issued for a shortened period.
Photographs that do not meet USCIS specifications. Form I-765 requires two passport-style photographs taken within 30 days of filing. Photos must meet USCIS photo requirements: white background, 2x2 inches, full face visible, no glasses. Photos from a standard photo booth that includes background color or head coverings (except for religious reasons) are frequently flagged.
Missing or inconsistent supporting documents. The standard document package for post-completion OPT includes the completed Form I-765, the OPT-recommended I-20, copies of all previous EADs (if any), a copy of the SEVIS fee receipt, a copy of the F-1 visa, copies of passport biographical page and any entry stamps, and two passport photographs. Each copy must be legible. USCIS issues a Request for Evidence (RFE) for missing items, which extends the total processing time significantly, or issues an outright rejection for applications that are fundamentally incomplete.
Filing outside the authorized window. As discussed above, applications received more than 90 days before the program end date or more than 60 days after it are automatically rejected. USCIS uses the date the application is received - not the postmark date - for online filings, and the date of delivery for paper filings. Students filing by mail should use a trackable shipping method and file well before any deadline.
After Submission: What to Expect
Once USCIS receives the application, the student receives a receipt notice (Form I-797) with a case number that can be used to track the application online. During this processing period, a student in valid F-1 status who has applied for post-completion OPT on time may remain in the United States for up to 60 days after the program end date. This is sometimes called the “OPT grace period,” though it does not authorize employment - work can only begin once the EAD is in hand and the start date printed on the card has arrived.
If USCIS issues an RFE, the student has a set deadline - typically 87 days from the RFE date - to respond with the requested documents. Failing to respond in time results in denial. A denial is not automatically appealable; in many cases, the only option is to refile, which may or may not be possible depending on whether the student is still within the application window.
Students who are approved will receive a physical EAD card by mail. The card shows an explicit start date and end date. Employers must verify employment authorization using the EAD as part of the Form I-9 process. The student’s name on the EAD must match exactly with the name on the I-9 and their identity documents - any discrepancy can complicate the verification process.

The USCIS online account system now allows students to file Form I-765 electronically, which provides instant receipt confirmation and eliminates the risk of postal delays losing a paper application.
