International students on Optional Practical Training (OPT) don’t lose status the moment a job ends — but the clock starts running immediately, and it’s stricter than most students realise. Here’s exactly how USCIS counts unemployment days, what counts as “employed,” and what happens if you cross the line.
The limits
- Standard post-completion OPT (12 months): 90 cumulative days of unemployment, maximum, across the full 12-month period.
- STEM OPT extension (24 additional months): 60 more days, for a combined 150 cumulative days across the initial OPT period plus the STEM extension.
These aren’t 90/150 consecutive days — they’re a running cumulative total. A week unemployed in month 2 and three weeks unemployed in month 9 both draw down the same bank of days. (USCIS — Optional Practical Training (OPT) for F-1 Students; USCIS — STEM OPT Extension)
When the clock starts — and what “employed” means
The count begins from your OPT start date printed on your Employment Authorization Document (EAD) — not your program end date, not the date you actually landed a job. If your EAD start date arrives before you’ve secured work, days start burning immediately.
To stop the clock, you need qualifying employment: paid or unpaid work (including some volunteer roles and self-employment) that is related to your field of study, at at least 20 hours per week. Multiple part-time roles can be combined to clear the 20-hour threshold. STEM OPT applies a stricter version of the same rule — the work must be at least 20 hours/week and directly related to your STEM degree, tied to a signed Form I-983 Training Plan with a genuine employer-employee relationship, not just any job.
What happens if you exceed the limit
Going over 90 cumulative days (or 150 for STEM OPT) triggers automatic termination of your SEVIS record, ending your F-1 status and OPT work authorization. This isn’t a warning-then-grace process — once the threshold is crossed, the record can be terminated without further notice, which puts you out of status immediately and creates real risk for any later US immigration filing (including an H-1B change of status).
Reporting requirements that feed the unemployment count
Your unemployment days aren’t tracked automatically from nowhere — they’re derived from what you and your school report:
- Standard post-completion OPT: report employment start/end dates, employer changes, and address changes to your Designated School Official (DSO), who has up to 21 days to log them in SEVIS. Gaps between reported employment are what generate unemployment days on your record.
- STEM OPT: stricter reporting — employer changes, loss of employment, and address changes must be reported within 10 days via the SEVP Portal (sevp.ice.gov/opt), plus a check-in to validate your information every 6 months, even with no changes.
Falling behind on reporting doesn’t stop the clock — it just means your DSO or SEVP finds out late that days have been accruing.
The 60-day grace period is a different thing
At the end of OPT (or STEM OPT, if you did the extension), F-1 students get a one-time 60-day grace period to prepare to depart the US, transfer to a new SEVIS program, or change status. This grace period is separate from the 90/150-day unemployment allowance — it doesn’t add to it, and it only starts once your OPT authorization has actually ended, not while you’re still mid-OPT and racking up unemployment days.
FAQ
Does part-time work under 20 hours a week stop the unemployment clock? No — for standard OPT and STEM OPT alike, qualifying employment generally needs to reach at least 20 hours per week (combining multiple jobs if needed) to count against the unemployment cap.
Does unpaid work count? Yes, unpaid work and some volunteer roles can qualify for standard post-completion OPT, provided the role is genuinely related to your field of study and meets the hours threshold — but it must still be reportable, real work, not a nominal arrangement.
If I’m approved for a cap-gap H-1B extension, does unemployment still count? Yes — unemployment accrued during an H-1B cap-gap extension of OPT still counts toward your overall 90/150-day limit. (USCIS — Extension of Post-Completion OPT and F-1 Status under H-1B Cap-Gap)
Can I appeal if my SEVIS record is terminated for exceeding the limit? There’s no routine appeal — terminated records generally require restarting your F-1 pathway (e.g., a new SEVIS record via readmission) rather than reinstating the old one. Talk to your DSO the moment you’re close to the limit, not after you’ve crossed it.
This is general guidance, not legal advice. OPT and SEVIS rules are enforced strictly and change over time — confirm your specific day count with your DSO and check current guidance on USCIS’s OPT page and Study in the States before making any decisions.
