Optional Practical Training (OPT) allows F-1 students to work in the United States in a job directly related to their field of study. It is one of the most time-sensitive processes an international student will encounter, and a single missed deadline or incorrectly completed form can delay or end work authorization entirely.

USCIS processes OPT applications through Form I-765, Application for Employment Authorization. Students do not file this form independently - they must first obtain a new I-20 from their Designated School Official (DSO) with the OPT recommendation endorsed before submitting the I-765 to USCIS. Understanding exactly when and how to file can make the difference between starting a job on time and waiting months without authorization.

OPT Eligibility Requirements

To qualify for pre-completion or post-completion OPT, a student must have been enrolled full-time for at least one full academic year in F-1 status. Part-time enrollment, leave of absence periods, or time spent in a different immigration status generally does not count toward that one-year requirement. Students who previously used OPT or Curricular Practical Training (CPT) for 12 months or more at the same degree level are ineligible for OPT at that level.

OPT comes in two forms: pre-completion and post-completion. Pre-completion OPT is used before graduation and counts against the total 12-month OPT allotment. Post-completion OPT, which most students pursue, begins after the program end date listed on the I-20. Students in STEM fields - specifically those on the Department of Homeland Security’s STEM Designated Degree Program List - may apply for a 24-month STEM OPT extension using Form I-765 and Form I-983, provided they have a qualifying employer enrolled in E-Verify.

A student must also maintain valid F-1 status at the time of application. If a student’s I-20 has expired, their SEVIS record has been terminated, or they have violated the terms of their F-1 status, they are not eligible to apply. USCIS will deny the I-765 in these cases, and the denial itself does not restore status.

Application Timing: The 90-Day Window

USCIS allows F-1 students to apply for post-completion OPT up to 90 days before the program end date on their I-20. The earliest date a student can submit the I-765 to USCIS is 90 days before that program end date. The latest date to file is 60 days after the program end date - this 60-day grace period follows graduation, during which the student must have already submitted the application.

The requested OPT start date on the I-765 must fall within 60 days of the program end date on the I-20. Students choose their own start date, but they cannot request a start date more than 60 days after their program end date. If approved, USCIS issues an Employment Authorization Document (EAD) with the start date the student requested - not the approval date. If the EAD arrives after the requested start date, employment cannot begin until the physical card is in hand.

USCIS standard processing times for Form I-765 have historically ranged from three to five months, though this varies significantly by service center and current workload. As of 2024, the USCIS website lists a processing time target of 3 to 3.5 months for most I-765 OPT applications, but actual times can exceed this. Students who miss the 90-day filing window and need faster processing may request premium processing only if it is available for their specific I-765 category - standard OPT I-765 filings are not eligible for premium processing as of current USCIS policy.

Common Reasons OPT Applications Are Rejected or Denied

USCIS distinguishes between a rejection and a denial. A rejection occurs before adjudication - the application is returned to the applicant because it was incomplete or improperly filed. A denial happens after USCIS reviews the case and determines the applicant does not qualify. Rejections are more recoverable, but only if the student is still within the eligible filing window.

The most frequent rejection reason is a missing or incorrect I-20 with the OPT recommendation. The I-20 submitted with the I-765 must be the most recent version, signed by the DSO within the past 30 days, and specifically endorsed for OPT. Submitting an old I-20, one missing a DSO signature, or one that lists a program end date that does not match the requested OPT start date timeline will result in rejection. USCIS also rejects applications where the I-765 form edition is outdated - students must use the current version found on the USCIS website at the time of filing.

Missing biographic documents cause a significant share of rejections. The required documents include a copy of the applicant’s passport biographical page, all previously issued EADs (if any), all previous I-20s, the F-1 visa stamp copy, and two passport-style photos that meet USCIS specifications. Omitting any of these, or submitting photos that do not meet the size and background requirements outlined in the Form I-765 instructions, leads to rejection without adjudication. Another common error is an incorrect mailing address - the EAD is mailed to the address on the form, and USCIS cannot forward documents; an incorrect or outdated address means the card ships to the wrong location, and the student must go through a lengthy replacement process using Form I-90.

STEM OPT Extension Errors

Students applying for the 24-month STEM extension face an additional layer of requirements. The employer must be enrolled in E-Verify, and the student must submit a completed Form I-983 (Training Plan for STEM OPT Students) signed by both the student and a company official. USCIS denies STEM extension applications when the employer’s E-Verify participation cannot be verified, when the I-983 is missing required fields, or when the STEM degree cited does not appear on the DHS STEM Designated Degree Program List. Students must also apply for the STEM extension before their initial OPT EAD expires - filing late results in a gap in work authorization that cannot be retroactively restored.

Maintaining Status During and After OPT

An approved EAD does not automatically extend F-1 status. During post-completion OPT, a student’s F-1 status remains valid as long as the EAD is valid, the student is working in a job related to their degree, and they maintain contact with their DSO. USCIS regulations at 8 CFR 214.2(f)(10)(ii) specify that OPT employment must be directly related to the student’s major area of study.

Unemployment during post-completion OPT is limited to a total of 90 days. Exceeding 90 days of unemployment during the standard OPT period, or 150 days during a STEM extension, results in a status violation. DSOs are required to report unemployment through SEVIS. Students who lose a job should immediately notify their DSO and actively document their job search efforts.

Once OPT ends, the student enters a 60-day grace period during which they may remain in the country to prepare for departure, change status, or take other action. Working during this grace period is not permitted. Students who receive an H-1B petition filed on their behalf before OPT expires may be eligible for a cap-gap extension, which is automatically granted under 8 CFR 214.2(f)(5)(vi) and extends F-1 status and EAD validity through September 30 of the applicable year.

The USCIS Form I-765 filing fee for OPT is currently $410 when filed by mail; students who file online through a myUSCIS account pay the same amount but receive faster receipt notices and can track case status in real time.
