Can You Work on a Student Visa in the US? F-1 Rules
A clear overview of the four ways F-1 students can work in the US, what counts as work, and how each category affects the next
F-1 students can work in the US, but only inside the rules. There are four authorized categories, each with its own eligibility timeline, hour cap, and approval route. On-campus employment opens first. Curricular Practical Training (CPT) covers work during your program. Optional Practical Training (OPT) covers work after graduation. A STEM OPT extension adds time for qualifying degrees. A narrow fifth path, severe economic hardship, opens after one full academic year.
Key takeaways
- F-1 students can work in four authorized categories: on-campus employment, CPT, OPT, and the STEM OPT extension.
- On-campus work is capped at 20 hours per week during the term, cumulative across every job, and can go full-time during scheduled breaks.
- CPT needs DSO authorization but no USCIS filing, and 12 months or more of full-time CPT eliminates post-completion OPT at the same education level.
- Post-completion OPT gives up to 12 months of work authorization per education level, and you can file Form I-765 starting 90 days before graduation.
- The STEM OPT extension adds 24 months but requires an E-Verify-enrolled employer.
- Working without authorization, even unpaid or remote for a foreign employer, can terminate your SEVIS record.
The four ways F-1 students can work
Each category sits on a timeline tied to your program and your SEVIS record. On-campus work opens at enrollment. CPT and pre-completion OPT need one full academic year in F-1 status, with limited graduate exceptions. Post-completion OPT and the STEM OPT extension come at and after graduation, in that order.
| Category | When you can do it | Hour limits | USCIS application required? |
|---|---|---|---|
| On-campus employment | Active F-1 from start date | 20 hours/week (term), full-time (break) | No |
| CPT | After one full academic year (graduate exceptions) | Part-time or full-time, DSO-set | No |
| OPT (pre-completion) | While enrolled, after one full academic year | 20 hours/week (term), full-time (break) | Yes (Form I-765) |
| OPT (post-completion) | After program completion | Minimum 20 hours/week | Yes (Form I-765) |
| STEM OPT extension | After initial OPT, with STEM degree | Minimum 20 hours/week at E-Verify employer | Yes (Form I-765) |
| Severe economic hardship | After one full academic year | 20 hours/week (term), full-time (break) | Yes (Form I-765) |
What counts as work on an F-1 visa
Work means any productive activity for an employer, paid or unpaid, US-based or foreign, in person or remote. Unpaid internships at for-profit companies, freelance gigs, and one-off paid projects all count. The one exception is volunteering for a role that is normally unpaid at a non-profit. Passive income, like dividends or savings interest, is not work.
What happens if you work without authorization
Unauthorized work is a status violation. It can end your SEVIS record, which ends your F-1 status and your right to work. You would have to stop working, and you may need to leave the US or apply to be reinstated. It can also affect future visa applications, so confirm a category applies before you start.
On-campus work for F-1 students
On-campus work is the easiest to start. Most students qualify from their first day with no USCIS application, and you can begin up to 30 days before classes. Your DSO gives you an authorization letter, which you take to the Social Security Administration with the employer's letter to get a Social Security number. Without that number you can be hired but not paid.
The limit is 20 hours per week while school is in session, counted across all your on-campus jobs together. Ten hours at the library plus twelve teaching is 22 hours, which is too many. During school breaks you can work full-time if you plan to enroll the next term. On-campus means the school's property or an affiliated site like a teaching hospital, so a third-party shop on campus may not count. Off-campus work in your first year is not allowed.
Curricular practical training (CPT)
CPT lets you work while enrolled, but only when the work is a required, credit-bearing part of your degree, and only after one full academic year. Graduate programs that require training sooner are the exception. Your DSO approves CPT on a new Form I-20, with no USCIS application or fee. It can be part-time (20 hours or less per week) or full-time.
One rule matters most. Twelve months or more of full-time CPT at one degree level removes your post-completion OPT at that level. Part-time CPT does not count and does not affect OPT. Some graduate programs offer CPT from day one, which is allowed when the training is a real course requirement but gets extra review on later H-1B and green card filings.
Optional practical training (OPT)
OPT gives you up to 12 months of work authorization per degree level, approved by USCIS and not tied to one employer. You can use it while enrolled (pre-completion) or after graduation (post-completion), though most students save it all for after.
Pre-completion OPT during the term is part-time, up to 20 hours per week, and it counts against your post-completion time at half rate. Six months of part-time pre-completion OPT uses up only three months, leaving nine. Full-time pre-completion OPT, allowed during breaks, counts at the full rate.
For post-completion OPT, file Form I-765 between 90 days before your end date and 60 days after, and within 30 days of your DSO's recommendation in SEVIS. You can be unemployed for up to 90 days total during post-completion OPT before your status is at risk.
STEM OPT extension
If your degree is on the DHS STEM list, you can add 24 months to post-completion OPT, for 36 months in total. The STEM OPT extension needs an employer enrolled in E-Verify and a Form I-983 training plan, and it raises the total unemployment limit to 150 days. A past STEM degree can qualify even if your latest degree is not STEM, if the conditions are met. Those 36 months usually cover two to three H-1B lottery cycles, which is why the extension matters for staying long-term.
CPT, OPT, and STEM OPT compared
| CPT | OPT | STEM OPT | |
|---|---|---|---|
| Eligibility prerequisite | One full academic year, plus an integral curricular component | One full academic year of F-1 status | Initial OPT plus a STEM-designated degree |
| Hour limits | DSO-set, part-time or full-time | 20 hours/week minimum (post-completion) | 20 hours/week minimum |
| USCIS application? | No, DSO authorizes | Yes, Form I-765 | Yes, Form I-765 |
| Maximum duration | Per program, no fixed cap | 12 months per education level | 24 additional months |
| Unemployment cap | None during enrollment | 90 days cumulative | 150 days cumulative |
| Employer requirement | Cooperative agreement with school | Directly related to degree | E-Verify enrolled, Form I-983 |
From OPT to H-1B: the cap-gap extension
If an employer files a change-of-status H-1B petition before your OPT ends and you are selected in the lottery, your F-1 status and work authorization continue automatically to bridge the gap to your H-1B start date.
As of June 2026, that extension runs until April 1 of the relevant fiscal year, or your H-1B start date if earlier, under the H-1B rule from January 2025. It applies only to change-of-status filings, not consular processing, and it ends if you are not selected or are denied.
Because the lottery is competitive, it helps to focus on employers that file H-1B petitions. Migrate Mate is a job board that shows US employers with a documented H-1B filing history, so you can see where to apply while you still have OPT time.

Can I count CPT hours toward my OPT if the employer later wants to hire me full-time?
No. CPT and OPT are separate authorizations. Hours worked under CPT don't count against your OPT allotment, and they don't give the employer any credit toward future work authorization. Once your CPT authorization ends, you need a new authorization category to continue working for that employer. Full-time CPT used for 12 months or more does eliminate post-completion OPT eligibility at the same degree level.
Can I work on-campus if I transfer to a new school mid-year?
Your on-campus work authorization resets when you transfer. You must enroll full-time at the new school before working, which means there's a gap between your last day at the old school and when you can start on-campus work at the new one. Your new DSO needs to issue a transfer-in I-20 and confirm your SEVIS record is active before any employment. Work authorization from your previous school ends the day your SEVIS transfer is initiated.
Can I work as a contractor or do freelance work on OPT?
Self-employment and 1099 contracting are allowed on post-completion OPT if the work is directly related to your degree. You're your own employer, which satisfies the employment requirement, but you must be able to document that the work constitutes at least 20 hours per week of degree-related activity. STEM OPT has a stricter requirement: self-employment doesn't satisfy the E-Verify employer requirement, meaning you can't extend your OPT under STEM OPT while self-employed. For STEM OPT you need a qualifying employer who is enrolled in E-Verify and signs your Form I-983 training plan.
Does Day-1 CPT affect my future H-1B petition?
Yes, it can, specifically if the school loses SEVP certification after you graduate. USCIS has denied H-1B petitions on the grounds that the underlying CPT was authorized by a school that was subsequently decertified, even when the student's enrollment was legitimate at the time. The practical risk: if your school's SEVP certification lapses between your graduation and your H-1B petition filing, the employer's attorney will need to document the CPT authorization's validity at the time it was issued. Check your school's current SEVP status through ICE's SEVP-certified school search before your H-1B petition is filed.
Can I get H-1B after OPT?
Migrate Mate filters employers by H-1B LCA (Labor Condition Application) filing history, which is the most direct indicator that an employer has an established H-1B process. The H-1B path requires your employer to file a petition during the annual cap registration in March, and if selected, your status changes to H-1B on October 1. If your OPT expires before October 1 after a timely H-1B filing, cap-gap protection extends your work authorization through September 30 automatically.
Can I fix a period of unauthorized work before applying for a new visa?
Unauthorized work can't be retroactively authorized. If you worked without authorization and then apply for a new visa or change of status, the officer reviewing your application will see the period and may deny on the basis of unlawful activity. An unlawful presence bar (the three-year or ten-year bar) applies only to overstays past 180 days, but unauthorized work is a separate inadmissibility ground that can apply even if you never overstayed. Consulting an immigration attorney before filing anything is the standard advice once unauthorized work has occurred.
Can F-1 students work remotely for a foreign company?
Not while you're physically in the U.S. F-1 work rules apply based on where you're sitting, not where your employer is incorporated. Working remotely for a foreign employer from inside the U.S. is unauthorized work and triggers SEVIS termination.
Can I do an unpaid internship without CPT?
If the internship builds the employer's business rather than only your degree, no. You still need CPT authorization before it starts, even unpaid. Volunteer work for a charity that doesn't normally pay anyone for the role is the only narrow exception, and the work must avoid displacing a U.S. worker.
How long is the F-1 visa valid?
F-1 status currently lasts for the duration of your studies, plus any approved OPT, plus a 60-day grace period, with no fixed end date on your I-94. The visa stamp itself can have a different expiration set by your country's reciprocity schedule, but the I-94 governs how long you can stay. A proposed 2026 rule may replace duration of status with a fixed end date, but it hasn't finalized.
Can I invest in stocks on an F-1 visa?
Yes. Passive investment income such as stocks, ETFs, savings interest, and dividends isn't "work" for F-1 purposes. Active day trading as a business, or income from operating a U.S. business, would be unauthorized work. Open a U.S. brokerage account with your SSN or Individual Taxpayer Identification Number (ITIN) once you have one.
What if my OPT EAD is delayed past my intended start date?
You can't legally start work until you physically hold the EAD card, and the approval notice alone isn't enough. If your card hasn't arrived 30 days after approval, contact USCIS through the Contact Center. File as early as the 90-day pre-completion window opens, since standard I-765 processing runs 60 to 90 days per the USCIS processing times tool. If your start date is firm, premium processing at $1,780 guarantees adjudication within 30 business days per the USCIS premium processing alert.
