Can You Work in the USA on a Student Visa? F-1, CPT, and OPT

Working in the USA on a student visa is legal, but only through specific authorized categories, and every category except one requires paperwork before you start the job. F-1 students have several routes: on-campus employment, Curricular Practical Training, Optional Practical Training, a STEM extension of OPT, severe economic hardship authorization, and internships with recognized international organizations. M-1 students, who study in vocational programs, can only work through post-completion practical training. The rules are strict, the penalties for getting them wrong are severe, and the safest move is always to talk to your school’s Designated School Official (DSO) before you accept any offer.

On-Campus Work for F-1 Students

On-campus employment is the one option that doesn’t require a separate application to USCIS. Your DSO authorizes it directly. Qualifying positions include jobs at school-owned facilities like the bookstore, library, or dining hall, plus roles with private companies that provide services to students on campus.¹

You can work up to 20 hours per week during the academic term and full-time during school breaks and annual vacations, provided you plan to register for the following term. Because there’s no USCIS filing, this is the fastest way to start earning after you arrive.¹

Curricular Practical Training

Curricular Practical Training (CPT) covers off-campus jobs built into your degree: internships, cooperative education placements, and work-study assignments tied to your major. Your academic department has to confirm that the training is either required for graduation or earns academic credit, and your DSO authorizes CPT in SEVIS and issues an updated Form I-20. You cannot start work until you have that endorsed I-20 in hand.¹

You generally need at least one academic year of full-time enrollment before you’re eligible. Graduate programs that require immediate practical experience can be an exception.¹

Watch the CPT clock carefully. If you accumulate 12 months or more of full-time CPT, you lose eligibility for OPT after graduation. Part-time CPT (20 hours per week or less) doesn’t trigger that penalty, so students who want both should track their full-time hours.¹

One more trap: even unpaid internships at for-profit companies can require employment authorization. The Department of Labor uses a “primary beneficiary test” with seven factors to decide whether an intern is legally an employee under the Fair Labor Standards Act.² The safe approach is to get CPT authorization for any for-profit internship, paid or not.

Optional Practical Training

Optional Practical Training (OPT) gives F-1 students up to 12 months of work experience directly related to their major. You can use it before graduating (pre-completion, part-time only during the school year) or after graduation (post-completion, full-time). Most students save the full 12 months for post-completion use.¹

The process begins with your DSO recommending OPT in SEVIS and issuing a new Form I-20 with the OPT dates. You then file Form I-765 with USCIS within 30 days of that recommendation. Miss the 30-day window and USCIS will deny the application outright. For post-completion OPT, the start date must fall within 60 days after your program end date.³

Once post-completion OPT starts, your F-1 status depends on staying employed. You cannot be unemployed for more than 90 days total during the 12-month period. Every day without qualifying employment counts, and going over puts your status at risk.¹

STEM OPT Extension

Students who earned a degree in an eligible science, technology, engineering, or mathematics field can add 24 months to the initial 12 months of OPT.¹ The extension carries requirements that regular OPT does not.

Your employer must be enrolled in E-Verify. Companies that aren’t enrolled cannot hire you under STEM OPT, no matter how strong the offer.⁴

Before your DSO can recommend the extension, you and your employer must complete Form I-983, a Training Plan describing your learning objectives, how the training ties to your STEM degree, how the employer will supervise and evaluate you, and where you’ll work. If you change employers during the 24 months, you must submit a new I-983 within 10 days of starting the new position.⁵

The unemployment allowance changes too. STEM OPT students get 150 days of aggregate unemployment across the entire OPT period, including the initial 12 months, rather than 90.⁶

Cap-Gap Extension

If your employer files an H-1B petition on your behalf while you’re on OPT, you may qualify for a “cap-gap” extension that bridges OPT expiration and the H-1B start date. When the petition is timely filed and requests a change of status, your F-1 status and work authorization automatically extend until April 1 of the relevant fiscal year, or until an approved H-1B start date, whichever comes first. If the petition is denied, withdrawn, or revoked, the extension ends immediately.⁷

Severe Economic Hardship

If unexpected financial trouble hits after you’ve started your program, you can apply for off-campus work authorization based on severe economic hardship. This covers situations like losing your financial aid, a sharp currency devaluation in your home country, or large unexpected medical bills. You must have been in F-1 status for at least one full academic year and be in good academic standing.¹

USCIS wants to see that on-campus jobs either aren’t available or don’t pay enough to close the gap. Document the emergency thoroughly: correspondence about lost funding, bank statements, evidence of exchange rate shifts, medical bills. The authorization requires filing Form I-765, and the “unforeseen” requirement gets real scrutiny.

International Organization Internships

F-1 students can also apply for authorization to intern with a recognized international organization such as the World Bank or United Nations, as covered by the International Organization Immunities Act. The organization must certify that the work falls within its sponsorship scope, your DSO must confirm eligibility on your Form I-20, and you file Form I-765 with USCIS for the actual work permit.⁸

M-1 Students Cannot Work During Studies

If you’re on an M-1 visa in a vocational or non-academic program, the rules are much tighter. No on-campus work. No off-campus work during your studies. The only employment option is practical training after you complete your program, and it is strictly rationed: one month of authorization for every four months of full-time study, capped at six months total. The training must connect directly to your vocational coursework.¹

A 12-month vocational program would produce three months of practical training. M-1 students have no equivalent of CPT and cannot extend the training period.

How to Apply and Get Paid

For any category that requires USCIS approval (OPT, STEM OPT, severe economic hardship, international organization internships, M-1 practical training), you file Form I-765, Application for Employment Authorization. The filing fee is $470 online and $520 by paper. USCIS mails a Form I-797 receipt notice with a tracking number, and some applicants are called in for biometrics.

If approved, USCIS issues an Employment Authorization Document (EAD) showing the exact dates you’re allowed to work. You cannot begin employment until you have the EAD in hand and the authorized start date has arrived. File as early as the regulations allow, and coordinate the timing with your school well before graduation for post-completion OPT.³

You’ll also need a Social Security number before starting any job. Apply in person at a Social Security Administration office with original documents proving your immigration status, work authorization, age, and identity, plus evidence of actual employment such as a pay slip or a signed letter from your supervisor showing the job, start date, and hours. Photocopies and notarized copies aren’t accepted.⁹

Taxes on Student Earnings

Earning U.S. wages means filing taxes, and international students face a few rules Americans don’t. For the first five calendar years in F-1, J-1, or M-1 status, you’re generally classified as a nonresident alien for tax purposes. During that period, you’re exempt from Social Security and Medicare taxes (FICA) on wages from authorized employment connected to the purpose of your visa. The exemption covers on-campus work, CPT, and OPT.¹⁰

The FICA exemption ends once you’ve been in the U.S. for more than five calendar years and meet the Substantial Presence Test, because you become a resident alien for tax purposes at that point. It also does not cover work that isn’t authorized or isn’t connected to the purpose of your student visa.¹⁰

If you earned U.S. income, file Form 1040-NR by April 15.¹¹ Even if you earned nothing at all, nonresident aliens in F, J, or M status must file Form 8843, Statement for Exempt Individuals, by June 15 of the following year. Skipping Form 8843 can create complications later when you apply for other immigration benefits.

What Unauthorized Work Costs

Federal regulations are blunt: any unauthorized employment by a nonimmigrant is a failure to maintain status.¹² That includes working more hours than allowed, working off campus without authorization, or starting a job before your EAD start date. No warning, no grace period.

Once you’re out of status because of unauthorized work, you start accruing unlawful presence. Reinstatement to valid F-1 status is generally not available to students who worked without authorization. More than 180 days of unlawful presence triggers a three-year bar on reentering the U.S. after departure, and more than one year of unlawful presence results in a ten-year bar. Those bars apply even if you later qualify for a different visa category.

The principle running through every category is the same: get authorization before you work, keep your paperwork current, and don’t assume a reasonable-sounding arrangement is automatically legal. Your school’s international student office is the first call, not the last.
