What is OPT?
Optional Practical Training (OPT) is a period of temporary employment authorization for F-1 students that allows you to work in the US in a job directly related to your major area of study. You get up to 12 months of OPT per degree level, and it comes in two forms:
- Pre-completion OPT — used before graduation, while you're still enrolled. Time used here counts against your 12-month total.
- Post-completion OPT — used after graduation. Most students use this form.
Your work must be in a job related to your field of study, but the rules are interpreted broadly. Most employers doing relevant work qualify.
The OPT application window
Timing is everything with OPT. Miss the window and you lose the ability to apply. The rules are strict:
USCIS processing takes 3–5 months in 2026. If you apply at graduation, your EAD won't arrive until months later and you'll have significant unemployment time eating into your 90-day limit. Apply as close to the 90-day window as possible.
What you need to file (Form I-765)
- Completed Form I-765 — use eligibility category (c)(3)(B) for post-completion OPT
- Filing fee: $470 online / $520 by paper
- Two identical passport-style photos (2×2 inches, white background)
- Copy of your passport bio page
- Copy of your F-1 visa
- Copy of your I-94 record
- Copy of all previous I-20s
- Copy of your new OPT I-20 (issued by your DSO)
Filing Form I-765 online at uscis.gov is faster than paper, gives you a receipt immediately, and lets you check status in real time. Always choose online unless your DSO instructs otherwise.
Common mistakes that get OPT denied
Post-completion OPT must use category (c)(3)(B). Using (c)(3)(A) or (c)(3)(C) causes automatic denial. Double-check before submitting.
Your DSO recommendation is time-stamped. Once 30 days pass, USCIS will reject the application. Request your OPT I-20 early and file within days of receiving it.
Form I-765 must be signed and dated. An unsigned form is rejected regardless of everything else being correct.
Photos must be identical, recent (taken within 30 days), 2×2 inches, and on a plain white background. Staple them correctly — don't tape or glue.
Include copies of every I-20 you've ever been issued, not just the current one. USCIS checks your complete immigration history.
Tracking unemployment days
This is where many students get into serious trouble. OPT comes with strict unemployment limits that, if exceeded, automatically terminate your F-1 status.
| OPT Type | Max unemployment | What counts as "unemployed" |
|---|---|---|
| Standard OPT (12 months) | 90 days | Any day your EAD is active but you have no qualifying employment |
| STEM OPT extension (24 months) | 150 days total across all OPT | Same — days accumulate across both OPT periods combined |
Unemployment days start counting the moment your EAD becomes active — not when you graduate. If USCIS approved an early OPT start date, you're already accruing days even before you've walked across the stage.
By 2026, DHS monitors unemployment in near real-time through SEVIS. If you change jobs or become unemployed, report it to your DSO within 10 days. Failure to report can trigger a SEVIS status termination within 48 hours of a discrepancy being detected.
STEM OPT extension
If your degree is in an eligible STEM field, you can apply for a 24-month extension, bringing your total OPT to 36 months. STEM OPT is one of the most valuable immigration benefits available to international students in the US.
Eligibility requirements
- Your degree must be on the DHS STEM Designated Degree Program List
- You must currently be on post-completion OPT (not pre-completion)
- Your employer must be enrolled in the E-Verify program
- You and your employer must complete a Training Plan (Form I-983)
When to apply
Apply no earlier than 90 days before your current OPT EAD expires. USCIS must receive your application before the EAD expiration date. If USCIS receives it on time and your case is pending when your EAD expires, you receive an automatic 180-day extension to continue working while they process.
STEM OPT reporting requirements
STEM OPT comes with ongoing reporting obligations you cannot miss:
- Report any changes in employer, address, or employment status to your DSO within 10 days
- Complete a self-evaluation at 12 months of your STEM OPT using Form I-983
- Your employer must submit an annual evaluation confirming you are meeting training goals
Cap-gap: bridging OPT to H-1B
If you're on OPT when your employer files an H-1B petition on your behalf and you're selected in the April lottery, there's a gap between when your OPT ends and when H-1B employment begins (October 1). The cap-gap rule fills this.
If your H-1B petition is selected in the lottery AND your OPT EAD expires between April 1 and September 30, your F-1 status and work authorization are automatically extended through September 30 (or October 1 if your petition is still pending). You do not file a separate application. Your DSO issues a cap-gap I-20 as proof.
Cap-gap only covers you if your employer's H-1B petition was properly filed, selected in the lottery, and isn't denied or withdrawn before October 1. If your petition is rejected or denied before the H-1B start date, your work authorization ends and you enter your grace period.
After OPT ends: your options
When your OPT (and STEM OPT if applicable) expires, your F-1 status ends. You have a 60-day grace period to take one of these actions:
- Start H-1B employment — if your H-1B was approved and your start date is in the future
- Change to another status — such as H-4 (dependent of H-1B), O-1, L-1, or another eligible visa
- Enroll in a new degree program — starting a master's or PhD resets your OPT eligibility for that degree level
- Depart the US — within 60 days of OPT expiration
You cannot continue working after your EAD expires, even one day into the grace period. The 60 days is only for making arrangements and departing or changing status — not for continued employment.
