How to Make Money as an International Student in the USA

If you are on an F-1 or J-1 visa, there are legal ways to make money as an international student in the USA, but each one requires a specific authorization before your first day on the job. F-1 students can work on campus, do Curricular Practical Training (CPT), use Optional Practical Training (OPT) before or after graduation, add a 24-month STEM extension if their field qualifies, or apply for off-campus work based on severe economic hardship. J-1 students earn money through program-based employment or academic training approved by their program sponsor. Paid or unpaid, on campus or off, the rule is the same: get the authorization in writing first.

On-Campus Jobs

On-campus work is the simplest way to start earning as an F-1 student because it does not require approval from U.S. Citizenship and Immigration Services (USCIS). The job has to be physically located on your school’s campus, or at an off-campus site that is educationally affiliated with your university. Positions with commercial businesses that operate on campus and serve students directly, like a bookstore or a dining hall run by an outside company, count too.¹

While classes are in session, you are limited to 20 hours per week. During official breaks and summer vacation, you can work full-time if you intend to register for the next term.¹ You do not file anything with USCIS, but your school’s international student office still has to authorize the position internally. Get that sign-off before your start date, not after.

Curricular Practical Training (CPT)

CPT lets you work off campus when the job is a required part of your degree program. The position has to be an internship, cooperative education placement, or similar experience that is built into your school’s established curriculum, and it must connect to your major field of study. Your Designated School Official (DSO) authorizes CPT directly, so no USCIS application is involved.¹

CPT can be part-time (20 hours or less per week) or full-time. Here is the trap: if you accumulate 12 months or more of full-time CPT at a given degree level, you lose eligibility for OPT at that same level.¹ That is a serious trade-off, because OPT is typically the best path to working after graduation. Part-time CPT does not count toward the 12-month threshold, so if you have a choice, part-time preserves your future options. Every full-time CPT month you use also gets deducted from your available post-completion OPT time.²

Optional Practical Training (OPT)

OPT is the main work authorization most F-1 students use after finishing a degree. You get up to 12 months per educational level, and the work has to relate to your major.¹ OPT can be used before graduation (pre-completion) or after (post-completion), but any pre-completion time is subtracted from your 12-month total.

When to File

The filing window for post-completion OPT is tight. You can submit Form I-765 as early as 90 days before your program end date, but no later than 60 days after.² Miss the 60-day deadline and you forfeit OPT entirely at that degree level. Your DSO must enter the OPT recommendation into your SEVIS record before you file, and you have to submit your application within 30 days of that recommendation.³ Processing times vary widely, from a few weeks to well over a year, so file as early as you can. You cannot begin working until your Employment Authorization Document (EAD) is approved and in hand.

The 90-Day Unemployment Cap

Once post-completion OPT starts, you are allowed a maximum of 90 days of aggregate unemployment during the entire OPT period. Every day you are not employed in a position related to your major counts against that total.¹ Exceeding 90 days violates your F-1 status. Line up a job as close to your OPT start date as possible, and treat gaps between roles as a real risk.

The 60-Day Grace Period

After OPT authorization expires, you get 60 days to prepare to leave the country, transfer to another school, or apply for a change to a different immigration status. You cannot work during this period.⁴

STEM OPT Extension

If your degree is in a qualifying science, technology, engineering, or mathematics field, you can apply for a 24-month extension on top of the standard 12-month OPT, for up to 36 months of post-graduation work authorization.¹ The qualifying fields are broader than most people expect. Beyond traditional engineering and hard sciences, the Department of Homeland Security’s designated list includes certain programs in business analytics, digital communications, psychology, homeland security, and agricultural sciences, among others.⁵ Check whether your program’s Classification of Instructional Programs (CIP) code appears on that list before assuming you do not qualify.

The STEM extension carries added conditions. Your employer must be enrolled in E-Verify, the federal system that confirms work eligibility.¹ You and your employer also complete a training plan on Form I-983, which outlines how the job relates to your degree. During the extension, you must report changes in employer, address, or employment status to your DSO within 10 days, and validate your SEVIS record with your DSO every six months.⁶

Cap-Gap Extension to H-1B

Students moving from OPT to an H-1B work visa often hit a timing gap, because OPT usually expires before the H-1B start date of October 1. The cap-gap extension fills that gap automatically for students whose employer has filed a timely, cap-subject H-1B petition. You do not file a separate application or receive a new EAD for the cap-gap period.⁷

One catch matters for earning income: if you have already entered your 60-day grace period when the H-1B petition is filed, your F-1 status gets extended, but you are not authorized to work during that extended period.⁷ If the H-1B petition is denied or withdrawn, the cap-gap extension ends.

Severe Economic Hardship Employment

If your finances fall apart because of circumstances you did not cause and could not have predicted, you can apply for off-campus work authorization based on severe economic hardship. Qualifying situations include losing a financial sponsor, major currency devaluation in your home country, or unexpected medical expenses. The financial crisis must have started after you arrived in the United States.¹

To qualify, you need to have been in valid F-1 status for at least one full academic year and be in good academic standing. You also have to show that on-campus employment is either unavailable or insufficient to cover your financial need.¹ This authorization goes through USCIS and requires filing Form I-765 under eligibility code (c)(3)(iii).³ If approved, you can work off campus for up to 20 hours per week during school terms and full-time during breaks, and the authorization lasts one year at a time.

Build the strongest case you can. Attach documentation that proves the crisis was both unforeseen and beyond your control: news articles about economic or political events in your home country, letters from family explaining changed circumstances, or bank statements showing the impact. A vague personal statement without supporting evidence is where most of these applications fail.

J-1 Work Options

J-1 students have different work rules than F-1 students, and the two are often confused. If your program involves work by design, such as a teaching assistantship, research fellowship, or summer work-travel placement, the employment is built into your program authorization. Your program sponsor’s responsible officer can also authorize part-time on-campus employment based on the terms of a scholarship or assistantship, or based on serious or unforeseen economic need.⁸

The J-1 equivalent of OPT is academic training. Your responsible officer can authorize up to 18 months of practical training during or immediately after your studies. For doctoral students, the limit rises to 36 months. Academic training can be paid or unpaid and must relate to your field of study.⁸ One advantage: academic training is authorized by your program sponsor rather than USCIS, so approval is generally faster than OPT.

Unpaid Internships and Volunteering

A common and dangerous misconception is that unpaid work does not count as employment and therefore does not need authorization. That is wrong. Off-campus work, whether paid or unpaid, requires authorization for F-1 and J-1 students. An unpaid internship at an off-campus company still needs CPT or OPT authorization, just like a paid one. Working without that authorization, even for free, is a status violation.

True volunteering for a nonprofit or charitable organization, where you receive no compensation and the organization does not benefit commercially from your labor, is generally permissible. The line between volunteering and unpaid employment is blurry, and getting it wrong carries the same consequences as any other unauthorized work. If you are unsure whether an opportunity is genuine volunteering or unpaid labor that needs authorization, talk to your school’s international student office before you start.

Getting Paid: Social Security Number and Taxes

You need a Social Security Number (SSN) to be paid legally in the United States, and you can only apply once you have authorized employment. For on-campus work, you will bring the Social Security Administration a letter from your DSO confirming your enrollment and employment details, along with evidence from your employer such as a signed letter describing the job and your start date.⁹ For OPT, you will need your approved EAD card, your I-20 with the OPT endorsement, your passport, and your most recent I-94 arrival record.

Expect the SSN card to arrive two to four weeks after your application is approved. If additional verification is needed, the wait can stretch to four to eight weeks. The Social Security Administration will not give you the number in advance of mailing the card, so build this lead time into your plans when starting a new job.

Earning U.S. income creates tax duties many students overlook. If you had any taxable U.S. income during the year, you must file a federal income tax return, typically Form 1040-NR as a nonresident alien. Even if you earned nothing, every F-1 and J-1 student physically present in the U.S. during the tax year must file Form 8843.

On payroll taxes, F-1, J-1, and M-1 students who have been in the U.S. for fewer than five calendar years are generally exempt from Social Security and Medicare taxes on wages from authorized employment. The exemption applies to on-campus work, CPT, and OPT positions. If your employer withholds these taxes anyway, which happens often because payroll systems default to withholding, alert the payroll department. The exemption only covers employment that USCIS has authorized and that connects to the purpose of your visa. After five calendar years in the U.S., or once you become a resident alien for tax purposes, the exemption ends.¹⁰

What Happens if You Work Without Authorization

Unauthorized employment as an F-1 or J-1 student is a deportable offense. Your SEVIS record can be terminated, which ends your legal status immediately. The consequences reach further than the moment: when you apply for any future immigration benefit, whether an H-1B work visa, permanent residency, or even a tourist visa, officers can review your tax returns, employment history, and prior immigration records. Unauthorized work in those records can lead to denial of the new application.

This applies to all unauthorized work, including unpaid positions and freelance gigs on platforms that do not check immigration status. There is no exception for small amounts of income or short periods of work. The single most important rule for international students earning money in the U.S. is straightforward: get authorization in writing before you start, every time.
