Can International Students Do Internships in the USA?

International students can do internships in the USA, but nearly every internship requires formal work authorization before the first day. For F-1 students, that authorization comes through Curricular Practical Training (CPT) or Optional Practical Training (OPT). J-1 exchange visitors use the Intern or Trainee categories through a designated sponsor. M-1 vocational students have a narrower route that only opens after they finish their program. Which path fits you depends on your visa, your degree stage, and how the internship connects to your studies.

CPT: The Fastest Route for F-1 Students

CPT is the quickest way for an F-1 student to start an internship because your school authorizes it directly. No federal application, no USCIS wait. Your Designated School Official (DSO) reviews the offer, endorses your Form I-20, and updates SEVIS.¹

To qualify, the internship must be an integral part of your degree program: it earns academic credit, fulfills a degree requirement, or is part of a cooperative education arrangement.² You also need to have been enrolled full-time at an SEVP-certified school for at least one full academic year. Graduate students whose programs require immediate practical experience can sometimes skip that waiting period.³ The work must relate directly to your major.

CPT comes in two forms based on weekly hours:

Part-time CPT: 20 hours per week or fewer, usually during the school term.
Full-time CPT: more than 20 hours per week, typically during summer or other breaks.³

Watch this closely. If you accumulate 12 months or more of full-time CPT at the same degree level, you lose eligibility for post-completion OPT entirely.² Part-time CPT does not count against OPT at all, which is why many students deliberately cap their hours at 20 per week to protect their post-graduation options.

You cannot start work before the CPT start date printed on your updated I-20, and SEVIS will not allow your DSO to backdate the authorization.⁴ Bring your offer letter to your DSO as soon as you have it.

OPT: 12 Months of Broader Work Authorization

OPT gives F-1 students up to 12 months of work authorization in a job related to their major.⁵ Unlike CPT, OPT requires a federal application: Form I-765 filed with USCIS, followed by a wait for your Employment Authorization Document (EAD). You cannot begin work until USCIS approves the application and the EAD start date arrives.

You can use OPT before or after finishing your degree:

Pre-completion OPT is available after one full academic year. It’s capped at 20 hours per week during the school term and can be full-time during breaks. Any time used here comes out of your 12-month total.
Post-completion OPT is the more common choice and gives you what remains of the 12 months to work after graduation.⁵

Timing is tight. For post-completion OPT, you can file as early as 90 days before your program end date and no later than 60 days after.⁶ Your DSO recommends OPT in SEVIS and issues an updated I-20 first; from that recommendation date, you have 30 days to get your Form I-765 to USCIS.⁷ Miss that window and USCIS will deny the application. Standard processing can run several months, so file early inside your window.

The STEM OPT Extension

If your degree is in an approved science, technology, engineering, or mathematics field, you can add 24 months to your initial 12-month OPT, for a total of 36 months of post-graduation work authorization.⁸

One requirement catches students off guard: your employer must be enrolled in E-Verify.⁹ Many small companies and startups aren’t, so check before you accept an offer you’re counting on for the extension. You can file up to 90 days before your current EAD expires, but not after it expires.⁶

J-1 Intern and Trainee Programs

The J-1 exchange visitor visa has two categories built specifically for practical work experience in the United States. Both require sponsorship by an organization designated by the U.S. Department of State, not by the host employer directly.¹⁰

J-1 Intern: for people currently enrolled at a foreign university or who graduated within the past 12 months. Programs run up to 12 months.¹¹
J-1 Trainee: for professionals with a foreign degree plus at least one year of related work experience, or five years of related experience without a degree. All qualifying experience must be from outside the U.S. Programs run up to 18 months.¹²

Once a sponsor accepts you, it issues Form DS-2019 (the Certificate of Eligibility for Exchange Visitor Status) and Form DS-7002, which sets out the goals and phases of the training.¹³ You use those documents to apply for the J-1 visa at a U.S. embassy or consulate.

J-1 Insurance Minimums

Every J-1 participant must carry health insurance meeting federal minimums for the full length of the program, and your sponsor is required to verify it. The coverage floor is:

Medical benefits of at least $100,000 per accident or illness
Repatriation of remains: $25,000
Medical evacuation: $50,000
Deductible no higher than $500 per accident or illness¹⁴

Many sponsors offer a group plan that meets these numbers. If you buy your own policy, check each threshold before your program begins.

The Two-Year Home Residency Rule

Some J-1 participants are subject to a two-year home-country physical presence requirement. If it applies, you must spend two years in your home country after the program ends before you can qualify for an H-1B, a green card, or certain other immigration benefits. The two years can be accumulated over time. It’s triggered if your program was funded directly or indirectly by the U.S. or your home government, if your field appears on your home country’s Exchange Visitor Skills List, or if you participated as a foreign medical graduate. Your DS-2019 will indicate whether the requirement applies. Don’t assume you’re exempt without checking; it can reshape your long-term plans.

M-1 Practical Training

M-1 vocational students have a narrower option. Practical training is the only work available to M-1 students, and it can only happen after the program of study is complete. Training must be full-time, and the duration depends on how long you studied: one month of practical training for every four months of full-time coursework, capped at six months.¹⁵

Zero days of unemployment are allowed during the authorized period, and part-time work is not permitted.¹⁵ If you haven’t chosen a visa category yet, factor these restrictions in.

Unpaid Internships Still Need Authorization

The most common misconception among international students is that an unpaid internship isn’t “employment” and therefore doesn’t need work authorization. In most cases it does. Both paid and unpaid internships related to your field of study generally require CPT or OPT for F-1 students.

USCIS has said students on post-completion OPT may work as volunteers or unpaid interns as long as the arrangement doesn’t violate labor laws and the work relates to their field of study.¹ The same principle applies to CPT: if the work relates to your major and is part of your curriculum, you need the CPT endorsement on your I-20 whether or not you’re paid. Working without proper authorization, even for free, can end your immigration status and block future visa eligibility. If you’re weighing an informal volunteer role with no connection to your field, ask your DSO first.

Costs, Processing Times, and Getting an SSN

CPT through your school is typically free apart from any tuition or course fees tied to the required academic enrollment. OPT is different. Form I-765 has a USCIS filing fee (check the current fee schedule at uscis.gov, since it’s adjusted periodically). Premium processing is available for an additional $1,780 as of March 2026 and guarantees USCIS action within a set timeframe.¹⁶ Without it, standard OPT applications can take several months.

J-1 costs vary by sponsor. On top of program fees, budget for the SEVIS I-901 fee, consular visa fees, and insurance premiums that meet the federal minimums. Sponsors generally require payment before they issue your DS-2019.

If your internship is paid, you’ll need a Social Security Number. Apply at a local Social Security office after your work authorization is in hand. The Social Security Administration recommends waiting at least 48 hours after reporting to your school so that DHS can verify your immigration status. Bring your passport, I-94, and either your I-20 with CPT endorsement or your EAD, depending on your authorization. Most cards arrive within about 14 days of approval.¹⁷

Staying in Compliance While You Intern

Getting authorized is only half the job. How you maintain status during the internship matters just as much.

On post-completion OPT, you cannot accumulate more than 90 days of unemployment during the 12-month authorization. Any day you’re not working at least 20 hours per week in a position related to your major counts.⁶ The STEM OPT extension adds another 60 days, for 150 days total across the combined period.⁸ Exceeding those limits ends your OPT and can affect your F-1 status.

You also have to report changes. Physical address, mailing address, employer name, and employer address updates are due within 10 days. F-1 students on OPT can update some information through the SEVP Portal; other changes go through your DSO.¹⁸ J-1 participants report changes to their sponsor, which updates SEVIS.

The consequences of getting compliance wrong are serious. Working without authorization, working outside the scope of what your documents allow (wrong employer, wrong dates, too many hours), or otherwise falling out of status can end your visa and bar future immigration benefits. For F-1 students, unauthorized employment makes you ineligible for OPT and can lead to removal proceedings. Depending on how long you stay out of status, multi-year bars on re-entry may apply. Any change to your internship, whether it’s a new employer, a new location, or a later end date, needs approval from your DSO or sponsor before it takes effect.
