Optional Practical Training (OPT) is a period of temporary employment authorization that allows F-1 students to work in the United States in a job directly related to their major field of study. It is one of the most time-sensitive applications in the student visa process, and errors in timing or documentation routinely result in denials or reduced work authorization periods.

USCIS processes OPT applications through Form I-765, Application for Employment Authorization. The agency’s average processing time for this form currently runs between three and five months, which makes understanding the filing window essential before a graduation date or program end date arrives.

Consult a licensed immigration attorney or your Designated School Official (DSO) before filing OPT paperwork to address your specific circumstances.

What Is OPT and Who Qualifies

OPT is available in two forms: pre-completion OPT, which can be used before a degree program ends, and post-completion OPT, which begins after a student finishes their academic program. Most students apply for post-completion OPT, which provides up to 12 months of employment authorization. Students in STEM fields - science, technology, engineering, and mathematics - may apply for a 24-month STEM OPT extension, bringing total authorized work time to 36 months.

To qualify for post-completion OPT, an F-1 student must have been enrolled full-time for at least one full academic year at a Student and Exchange Visitor Program (SEVP)-certified school. Students who have already used 12 months or more of full-time Curricular Practical Training (CPT) are ineligible for OPT. Part-time CPT usage does not count against OPT eligibility. The regulations governing this are found at 8 CFR 214.2(f)(10)(ii).

Each degree level carries its own 12-month OPT allotment. A student who used OPT after a bachelor’s degree can still apply for a separate 12-month OPT period after completing a master’s program, provided they have not exceeded their cap at that education level.

The Application Window and Why Timing Matters

The filing window for post-completion OPT opens 90 days before a student’s program end date and closes 60 days after it. The I-765 application must be received by USCIS within this window. Filing outside of it results in automatic denial, with no exceptions granted for postal delays or administrative errors.

Before filing with USCIS, a student must obtain a new OPT-recommended Form I-20 from their DSO. The DSO enters the OPT recommendation into the Student and Exchange Visitor Information System (SEVIS), and the I-20 must reflect this recommendation. USCIS will not approve an OPT application that lacks a properly endorsed I-20. Students should request the new I-20 from their DSO at least 30 days before they intend to file, as DSOs at large universities may have processing queues of their own.

The requested OPT start date on the I-765 must be between the program end date and 60 days after it. Students cannot request a start date more than 60 days after their program ends. If an application is pending and the chosen start date passes, USCIS will assign the approval date as the new start date - cutting into the total 12-month authorization period. For this reason, requesting a start date later than necessary reduces the available work authorization without any benefit.

How to File Form I-765 for OPT

Filing the I-765 requires assembling a specific set of documents. USCIS requires the completed I-765 form, two passport-style photos, a copy of the OPT-recommended I-20, copies of all previous I-20s, a copy of the F-1 visa stamp, copies of any previous EADs (Employment Authorization Documents), a copy of the passport biographical page, and a copy of the most recent I-94 arrival/departure record.

The filing fee as of mid-2024 is $410 for paper filing. USCIS began accepting online filing for the I-765 for certain categories; F-1 OPT applicants should verify current online filing availability on the USCIS website before submitting. Paper applications are mailed to one of two USCIS lockbox facilities depending on the student’s location - the correct address is listed in the I-765 form instructions and changes periodically. Using an outdated mailing address is a common cause of rejected filings.

Once USCIS accepts the application, it issues a receipt notice (Form I-797). Students should track the case using the receipt number on the USCIS online portal. If a Request for Evidence (RFE) is issued, the student typically has 87 days to respond. Failure to respond within that window results in denial.

Common Reasons OPT Applications Are Rejected or Denied

Filing outside the application window is the most straightforward rejection. If USCIS receives the I-765 before the 90-day opening date or after the 60-day post-program closing date, the application is rejected and the filing fee is not refunded. Postal tracking records from the carrier are not treated as the filing date; USCIS uses the date of receipt at the lockbox facility.

Missing or incorrect I-20 is the second most common issue. An I-20 that is not endorsed for OPT by the DSO, that carries an incorrect program end date, or that does not match the student’s name exactly as it appears on their passport will cause delays or denial. Any name discrepancy between USCIS records and the I-20 must be corrected before filing.

Ineligibility due to full-time CPT trips up a notable number of applicants. Students who accumulate 12 months of full-time CPT authorization sometimes do not realize this makes them ineligible for OPT. The CPT months are recorded in SEVIS and are visible to USCIS. Applying for OPT after exceeding the CPT threshold results in denial.

Photographs that do not meet USCIS specifications are a frequent reason for rejection at the lockbox stage. USCIS requires photos taken within 30 days of the application, measuring 2 inches by 2 inches, with a white or off-white background. The applicant’s name and I-94 number must be written lightly on the back. Photos printed from smartphones or taken in non-compliant lighting are regularly flagged. After receiving an Employment Authorization Document (EAD), students must not begin working before the start date printed on the card, even if the card arrives early - working before the authorized start date violates F-1 status and can result in removal proceedings.

STEM OPT Extension Considerations

Students pursuing the 24-month STEM OPT extension file a separate I-765 along with Form I-983, Training Plan for STEM OPT Students. The employer must be enrolled in E-Verify, a federal employment eligibility verification program. If the employer is not in E-Verify, the extension cannot be approved regardless of the student’s qualifications.

The STEM OPT extension application must be filed at least 90 days before the initial OPT EAD expires. If filed within 90 days of expiration and the current OPT EAD is still valid, USCIS grants an automatic 180-day extension of the existing work authorization while the new application is pending. Filing after the expiration of the OPT EAD eliminates this cap-gap protection, leaving the student without valid work authorization during processing.

A student whose STEM OPT extension is denied has 60 days from the denial date to either depart the United States or transfer to a new school and change status. Reapplication after denial requires addressing the specific grounds cited in the denial notice, which USCIS provides in writing with each adverse decision.

The SEVIS record for an F-1 student on OPT remains active and must be maintained. A student on OPT who is unemployed for more than 90 cumulative days (150 days for STEM OPT) is considered to have violated their OPT terms, which terminates the SEVIS record and ends lawful status. Reporting any employment changes to the DSO through the OPT portal within 10 days of the change is required by regulation at 8 CFR 214.2(f)(17).
