The F-1 OPT Unemployment-Days Limit, Explained

What the unemployment limit is and why it exists

Post-completion Optional Practical Training (OPT) lets an F-1 graduate work in a field directly related to their major. But OPT is training tied to your F-1 status, not an open-ended work permit — so U.S. Department of Homeland Security (DHS) rules cap how long you can go without a qualifying job during your authorized period.

The caps are counted in days of unemployment and tracked automatically in the government's Student and Exchange Visitor Information System (SEVIS). Going over the limit is a status problem, not a paperwork technicality: it can end your OPT and your ability to stay.

This is general information, not immigration or legal advice. The exact rules can change — always confirm the current numbers and your own situation on the official government source and with your Designated School Official (DSO).

• Post-completion OPT: a maximum of 90 days of unemployment.
• STEM OPT extension: a maximum of 150 days of unemployment across the whole OPT period (see below).
• The clock is tracked in SEVIS, not by you manually.

The two numbers: 90 days and 150 days

On standard post-completion OPT, an F-1 student may not accrue more than an aggregate of 90 days of unemployment during the authorized OPT period, per DHS. "Aggregate" means the days add up across the whole period, whether they come in one stretch or several.

If you receive the 24-month STEM OPT extension, the overall unemployment allowance rises to 150 days total. DHS describes this as the original 90 days during the initial post-completion OPT plus an additional 60 days during the STEM extension. The 90 days you may have already used carry over into that 150-day total — the STEM extension does not reset your counter to zero.

Because these are the current published figures and can be updated, verify the exact limits on the USCIS and Study in the States (SEVP) websites before you rely on them.

• 90 days — standard post-completion OPT.
• 150 days total — with the STEM OPT extension (90 + 60 more).
• Days already used on post-completion OPT count toward the 150.

How SEVIS counts a day of unemployment

SEVIS counts each day that your record has no valid employer information as a day of unemployment, starting from your OPT start date (the start date on your Employment Authorization Document, or EAD). If your record shows a qualifying job, those days do not count against you.

Weekends, holidays, and gaps between two jobs all count if no employer is listed for those dates. This is why a slow job search early on quietly burns days even before you feel "unemployed." The Unemployment Counter in SEVIS shows days allowed, days accrued, and days remaining for your active OPT or STEM OPT period.

• A day with no employer in SEVIS = a day of unemployment.
• The count begins on your EAD start date, not your graduation.
• Gaps between jobs count if the record shows no employer.

What counts as 'employed' on OPT

OPT is meant to be practical training in your field, so "employment" for the counter has specific meaning. On standard post-completion OPT, DHS recognizes several arrangements that can keep the clock stopped, including paid work, and — under the rules — certain unpaid or volunteer training and self-employment, provided the work is directly related to your major and meets the published conditions.

STEM OPT is stricter. Employers must be enrolled in E-Verify, the training must follow a formal Form I-983 training plan, and some arrangements allowed on standard OPT (such as certain volunteer or unpaid roles) are not permitted on the STEM extension.

The minimum-hours expectation, the treatment of self-employment, and the STEM employer conditions are all defined by DHS and can change. Confirm what qualifies for your specific case with your DSO and on the official pages before assuming a role "counts."

• Work must be directly related to your degree.
• Standard OPT and STEM OPT have different rules on what counts.
• STEM OPT requires an E-Verify employer and a Form I-983 plan.

Reporting is how you stop the clock

The counter only reflects what your record says. If you have a job but never reported it, SEVIS keeps counting you as unemployed. Reporting your employer — and any changes — is how you protect your remaining days.

Federal rules require you to notify your DSO of changes to your name, address, employer, and interruption of employment within 10 days. Your DSO then updates SEVIS (regulations allow the DSO up to 21 days to enter the change). Report a new job promptly, report when a job ends, and keep your address current.

Because reporting stops the count as of the employment dates you supply, delays can leave phantom unemployment days on your record. Reporting on time — not perfectly, but on time — is the single most useful habit on OPT.

• Tell your DSO within 10 days of any employment or personal-information change.
• Report both starting and ending a job.
• Unreported employment still counts as unemployment in SEVIS.

What happens if you go over — and how to avoid it

Exceeding your unemployment limit can cause your SEVIS record to be terminated and end your authorized OPT, which then affects your ability to remain in the United States. This is a serious consequence, so the goal is to never get close to the edge.

Check your accrued days regularly (your DSO can read the SEVIS Unemployment Counter with you), report every job on time, and remember that qualifying part-time, unpaid, or self-employment training may keep the clock stopped while you search — if it meets the rules. If you are running low, talk to your DSO early about options such as the STEM extension (if eligible) or a change of status.

We do not guarantee any outcome, and immigration decisions rest with the U.S. government. Use this guide to understand the mechanics, then verify specifics on the official source and act on your DSO's guidance.

• Going over the limit can terminate your record and end OPT.
• Monitor your accrued days with your DSO throughout OPT.
• Ask your DSO early about the STEM extension or a change of status if days are running low.
