An international student on an F-1 visa can generally form a company. The difficulty is not the paperwork that creates it, it is what the student does inside it. Performing work, even unpaid, can count as employment, and F-1 status allows employment only in limited, authorized ways.
What F-1 status allows
The F-1 employment rules permit on-campus work within limits, off-campus work only through specific authorizations, and practical training tied to the degree. There is no general permission to run a business full time. Whether a task counts as employment depends on the facts, so a student’s designated school official is the right first stop.
Work permissions that may apply
Curricular Practical Training (CPT)Work authorization for F-1 students for training that is an integral part of an established curriculum and directly related to their major. A designated school official authorizes it in SEVIS and on the Form I-20, and the student may start only after receiving the endorsed I-20. Students generally need one full academic year of enrollment first, and 12 months or more of full-time CPT makes a student ineligible for post-completion OPT at that education level.See it in the glossary must be an integral, required part of the curriculum. SEVP issued guidance on August 24, 2026 that narrowed how schools may authorize CPT, so a startup that is simply optional or elective generally does not fit. Post-completion Optional Practical Training (OPT)Temporary work authorization that lets eligible F-1 students work in a job directly related to their field of study. It can be used before or after completing a program, for up to 12 months in total at each education level, and students with certain STEM degrees can apply for a 24-month extension. USCIS grants it on Form I-765 after the school's designated school official recommends it.See it in the glossary is more flexible than CPT, but the 24-month STEM OPT extension requires an employer-employee relationship and an employer enrolled in E-Verify, which makes solo self-employment a poor match for that extension.
Owning versus working
Holding shares, or having an idea, is different from working for the company. A student who writes code for, sells for or manages their own startup without authorization risks a status violation. The same caution applies to unpaid founder work. This is a common trap because the company can look like a hobby while the activity still counts as employment.
What comes after study
Founders often need a different status to work in their own company. Options include the E-2 treaty investor category for eligible nationalities, or an Cap-subject and cap-exempt (H-1B)The H-1B category has an annual limit of 65,000 new visas or statuses per fiscal year, plus 20,000 more for people with a U.S. master's degree or higher. Petitions counted toward that limit are cap-subject. Petitions from higher education institutions, their related or affiliated nonprofits, and nonprofit or governmental research organizations are cap-exempt.See it in the glossary where the company can establish a genuine employer-employee relationship with the founder, which is harder when the founder owns most of it. Compare the routes in the E-2 treaty investor visa, or the startup-focused E-2 versus L-1 new office comparison.
Practical steps
Talk to the school before starting anything, keep clear records of what work is done and by whom, and avoid taking pay for services without authorization. Our overview of the F-1 student visa lists the baseline rules, and the background on why study does not lead automatically to permanent residence is in our earlier explainer.
