Visitors on the Visa Waiver Program (ESTA), B-1 or B-2 status, F-1* status, or F-2 dependents are generally NOT permitted to fundraise or work in the United States. It is expected that all of your expenses come from outside the United States, and working or fundraising for expenses (e.g. car washes) may be a violation of U.S. immigration law. * Degree-seeking F-1 students may be eligible to apply for Optional Practical Training (OPT) – a work-permit to allow you to work in the U.S. for up to 1-year, in your field of study, after the completion of your program. Our F-1 visa team can advise you on this matter.
