The F-1 visa has the strictest default work rules of any major study destination — no general off-campus work permission exists at all, unlike the UK, Canada, or Australia, where a standard weekly hours cap applies to off-campus jobs from day one. In the US, everything outside a narrow on-campus allowance requires a specific, separate work authorization, and getting the category wrong — working off-campus without CPT or OPT, or misunderstanding what counts as "on-campus" — is treated as unauthorized employment, one of the most serious F-1 status violations there is. This guide walks through exactly what's permitted, what changed in 2026, and how the different authorization categories fit together.
For a side-by-side comparison of how the US rules stack up against the UK, Canada, Australia, and other destinations, see our general guide to part-time work rules by country.
Quick Reference: F-1 Work Authorization at a Glance
| Category | Where | Hours (Term) | Hours (Break) | Requires Separate Authorization? |
|---|---|---|---|---|
| On-campus employment | On your own campus (or certain off-campus locations educationally affiliated with your school) | Up to 20 hrs/week | Full-time (40 hrs/week) | No — permitted under standard F-1 status |
| CPT (Curricular Practical Training) | Off-campus, tied to your curriculum | Part-time or full-time, per DSO authorization | Full-time if authorized | Yes — DSO authorization required before starting |
| OPT (Optional Practical Training) | Off-campus, in your field of study | Full-time (or part-time pre-completion) | N/A | Yes — USCIS-approved EAD card required |
| STEM OPT Extension | Off-campus, STEM field, E-Verify employer | Full-time, minimum 20 hrs/week | N/A | Yes — separate USCIS application, on top of standard OPT |
| Severe Economic Hardship | Off-campus, any employer | Up to 20 hrs/week | Full-time | Yes — USCIS approval, requires 1 full academic year in status first |
On-Campus Employment
On-campus work is the only category available to F-1 students without applying for anything beyond your standard student status — no separate USCIS filing, just your school's own hiring process (library jobs, dining hall, research assistant roles, bookstore, etc.).
- Cap: 20 hours per week while school is in session; full-time (up to 40 hours/week) during official school breaks and the summer if you're returning the following term
- What counts as "on-campus": work physically at the school, or at an off-campus location that is educationally affiliated with your program (for example, an on-campus contractor like a food service company, or research funded by an affiliated grant) — a private employer that simply happens to have an office near campus does not count
- When you can start: as soon as your F-1 status is active (after your program start date on your I-20), no waiting period required
Because this cap is tracked by hours, not shifts, combining multiple on-campus jobs (e.g., a library job plus a research assistantship) still counts toward the same 20-hour weekly total — going over it, even across two different campus employers, is a violation.
Curricular Practical Training (CPT)
CPT authorizes off-campus employment that is an integral, curriculum-required part of your academic program — most commonly a required internship or co-op.
Eligibility
- Full-time enrollment for at least one full academic year (with a documented exception for some graduate programs that require practical training earlier in the curriculum)
- Not enrolled in an English-language training program
- A confirmed job offer/training position tied to your specific curriculum
- Prior written authorization from your Designated School Official (DSO) — CPT approved retroactively, or started before authorization is issued, is treated as unauthorized work
Important 2026 change
In 2026, SEVP (the Student and Exchange Visitor Program within DHS) issued tighter guidance narrowing what counts as "an established curriculum" for CPT purposes — under the new interpretation, CPT eligibility is limited to experiences required of all students in a degree program (domestic and international alike) and formalized through a cooperative agreement between the school and employer, rather than the looser "related to your major" standard many schools had applied previously. This materially affects programs (especially some master's programs) that used a broadly defined "CPT elective" or internship-for-credit course as their basis for authorizing CPT. Confirm directly with your DSO whether your specific program's CPT pathway still qualifies under the current guidance before accepting an offer that depends on it — this is exactly the kind of rule that shifts between cohorts, so don't rely on what a senior student did the year before you.
The 12-month full-time CPT trap
Accumulating 12 months or more of full-time CPT makes you permanently ineligible for OPT afterward. Part-time CPT (20 hours/week or less) does not count against this limit, no matter how much of it you do — only full-time CPT triggers the OPT eligibility loss. If your program involves a full-time co-op semester, ask your DSO explicitly how much of your OPT eligibility, if any, it will consume.
Optional Practical Training (OPT)
OPT authorizes temporary employment directly related to your major field of study, and unlike CPT, it isn't tied to a specific curriculum requirement — you apply for it independently through USCIS.
| Detail | Rule |
|---|---|
| Standard OPT length | 12 months, usable before graduation (pre-completion, part-time during term/full-time during breaks) and/or after graduation (post-completion, full-time) |
| Application timing | File with USCIS as early as 90 days before your program end date, no later than 60 days after |
| Processing | Apply for an Employment Authorization Document (EAD) — you generally cannot start work until the EAD is approved and in hand |
| Unemployment limit | Up to 90 days of unemployment during standard post-completion OPT |
| Field requirement | Job must be directly related to your degree field — a marketing job on an OPT tied to a computer science degree is a violation |
STEM OPT Extension
Graduates with an eligible STEM degree can apply for an additional 24 months of OPT beyond the standard 12, for a total of up to 36 months of post-completion work authorization — a major advantage for STEM graduates over non-STEM peers.
| Detail | Rule |
|---|---|
| Extension length | 24 additional months, on top of the initial 12-month OPT |
| Eligible degree | Must be in a DHS-designated STEM field from an SEVP-certified, accredited school |
| Employer requirement | Employer must be enrolled in E-Verify |
| Additional unemployment allowance | 60 extra days, for a combined maximum of 150 days of unemployment across the full 36-month OPT + STEM OPT period |
| Reporting | Requires more frequent validation reporting to your DSO than standard OPT |
Note on 2026 regulatory uncertainty: proposed changes to STEM OPT rules were set to take effect in September 2026 but were blocked by a federal court order shortly before their effective date, leaving the prior rules in place while litigation continues. This is a live legal situation — confirm the current rule with your DSO or an immigration attorney before making plans that depend on STEM OPT specifics, rather than relying on any single source (including this one) as the final word.
Off-Campus Work for Severe Economic Hardship
A narrower, less commonly used pathway exists for students facing serious, unforeseen financial difficulty.
- Eligibility: at least one full academic year in valid F-1 status, good academic standing, and a documented "severe economic hardship" caused by circumstances beyond your control (loss of financial support, major currency devaluation, unexpected medical costs, a sharp tuition or cost-of-living increase)
- Process: requires a USCIS application (Form I-765) with your DSO's recommendation — this is not something your school can approve on its own, unlike CPT
- Hours: up to 20 hours/week while school is in session, full-time during official breaks
This route is intended as a genuine hardship safety net, not a general alternative to CPT/OPT — approval requires documented evidence of the hardship, and it's a meaningfully slower and less certain process than either of the curriculum-based pathways.
Common Mistakes F-1 Students Make
- Assuming "part-time off-campus" is generally allowed. Unlike UK, Canadian, or Australian student visas, F-1 has no general off-campus work allowance — every off-campus job needs a specific authorization category (CPT, OPT, or hardship approval).
- Starting CPT before written DSO authorization is issued. Even a genuine, curriculum-relevant internship counts as unauthorized work if you start before the authorization date on your CPT I-20.
- Not tracking full-time CPT months. Losing OPT eligibility because of an unplanned full-time CPT semester is one of the most common and most regretted mistakes F-1 students make — always ask your DSO for a running total.
- Working before the OPT EAD card physically arrives or is approved, not just after filing the application — USCIS filing receipt is not the same as work authorization.
- Misjudging what counts as "on-campus." A job at a coffee shop physically located in a university-owned building is not automatically "on-campus" for F-1 purposes unless it meets the educational-affiliation test — confirm with your international student office before assuming.
- Ignoring the field-of-study requirement on OPT. Taking a job unrelated to your degree field while on OPT, even if it pays better, is a violation that can jeopardize your status.
FAQ
Can F-1 students work off-campus at all without CPT or OPT? Generally no, except under the narrow severe economic hardship pathway, which requires a full academic year in status and USCIS approval. Otherwise, off-campus work requires CPT (curriculum-tied) or OPT (post-authorization, field-related).
How many hours can I work on-campus as an F-1 student? Up to 20 hours per week while classes are in session, and full-time (up to 40 hours/week) during official school breaks, including summer if you're returning for the following semester.
Does CPT use up my OPT eligibility? Only full-time CPT counts against OPT eligibility, and only once you accumulate 12 months or more of it. Part-time CPT (20 hours/week or less), regardless of duration, does not reduce your OPT eligibility.
What's the difference between OPT and the STEM OPT extension? Standard OPT gives 12 months of work authorization in your field after (or before) graduation. The STEM OPT extension adds up to 24 more months — total up to 36 months — but only for graduates of DHS-designated STEM degrees working for E-Verify-enrolled employers.
Did CPT rules actually change in 2026? Yes — SEVP issued narrower guidance on what counts as an "established curriculum" for CPT eligibility in 2026, tightening the standard many schools previously used for internship-based CPT programs. Confirm with your DSO whether your specific program still qualifies before relying on CPT for an upcoming internship.
Can I work for a company that isn't E-Verify enrolled during standard OPT? Yes — the E-Verify employer requirement applies specifically to the STEM OPT extension, not standard 12-month OPT.
