F-1 OPT Deadlines: The 90/60-Day Window You Cannot Miss

Updated July 25, 2026

If you are an F-1 student planning to work in the US after graduation, post-completion Optional Practical Training (OPT) runs on one unforgiving window: you can generally apply starting 90 days before your program end date, and no later than 60 days after it. USCIS must receive your application within that window — and there is an additional requirement that your application arrive within 30 days of your DSO entering the OPT recommendation in SEVIS.

That is roughly a five-month span in total, which sounds generous until you are juggling finals, graduation, a move, and a job search at the same time. Students miss this window every year, and unlike most immigration deadlines, this one has essentially no forgiveness built in. Here is how the clocks work and how to stay ahead of them.

The three clocks in an OPT application

First clock: the window opens 90 days before the program end date listed on your I-20. You cannot file earlier. Applying early in this window is the standard advice, because your OPT cannot begin until the application is approved and your employment authorization is in hand.

Second clock: the window closes 60 days after your program end date. This is a hard deadline — USCIS must receive the application by then, not postmark it, not have it in transit. Filing on day 59 of the grace period is legal but leaves zero margin for a rejected payment, a missing signature, or a returned package.

Third clock, the one that surprises people: your Designated School Official (DSO) must recommend OPT in SEVIS before you file, and USCIS must receive your application within 30 days of that recommendation. A recommendation obtained early and then left sitting can expire out from under an otherwise timely application.

  • Window opens: 90 days before your I-20 program end date
  • Window closes: 60 days after your program end date — received by USCIS, not postmarked
  • File within 30 days of your DSO’s SEVIS recommendation
  • Check uscis.gov for current forms, fees, and filing details before submitting

Why filing early beats filing eventually

OPT approval is not instant, and you generally cannot start working until it is granted. Every week you wait to file inside the window is a week of potential work authorization pushed further out. Students who file at the start of the 90-day pre-completion window put themselves in the best position to start work close to their chosen start date; students who file deep in the 60-day grace period often watch job start dates slip.

Early filing also buys you error margin. Applications get rejected for fixable problems — fee issues, photo problems, missing pages. Caught in month one, a rejection is an annoyance. Caught in the final days of the grace period, it can be the end of your OPT eligibility entirely.

The STEM OPT extension has its own deadline

If your degree is in a qualifying STEM field, you may be eligible for the STEM OPT extension, which adds substantial additional work authorization on top of your initial OPT. The critical rule: you must file for the extension before your current OPT expires. File on time and you can generally keep working while the extension is pending; miss the expiration date and the door closes.

The STEM extension also requires an employer enrolled in E-Verify and a formal training plan, so it is not a last-minute filing even in the best case. Mark your OPT expiration date the day your initial OPT is approved, and start the extension conversation with your DSO and employer months ahead. Requirements and current details are on uscis.gov.

Map the dates the day you know your program end date

Everything in the OPT timeline is computable from one date: your I-20 program end date. Ninety days before it, your filing window opens. Sixty days after it, the window slams shut. The moment that end date is set, you can put every milestone on a calendar — and you should, because no one sends F-1 students deadline notices.

Set a reminder anchored to your program end date with nudges starting well before the window opens: time to meet your DSO, request the SEVIS recommendation, prepare the application, and file early with room to recover from any hiccup. Your OPT is a one-shot window; treat the reminder as part of the application.

Frequently asked questions

When can I apply for OPT?

For post-completion OPT, you can generally file as early as 90 days before your I-20 program end date, and USCIS must receive your application no later than 60 days after that end date. You also must file within 30 days of your DSO entering the OPT recommendation in SEVIS.

What happens if I miss the 60-day OPT deadline?

If USCIS does not receive your application within 60 days of your program end date, you generally lose eligibility for post-completion OPT for that program. There is no routine late-filing forgiveness, which is why filing early in the window matters so much.

Can I start working while my OPT application is pending?

Not for initial post-completion OPT — you need the approved employment authorization in hand before you begin work. The STEM OPT extension is different: if you file before your current OPT expires, you can generally continue working while the extension is pending.

When do I need to file for the STEM OPT extension?

Before your current OPT expires — that is the hard deadline. Because the extension requires an E-Verify employer, a training plan, and a fresh DSO recommendation, start the process months ahead of your OPT end date. See uscis.gov for current requirements.
