Can a foreigner work for a U.S. employer while here on a B-1 business visitor visa?
A. No. The prominent feature of this category is that the alien cannot engage in gainful employment in the United States. Key here is whether the alien will be paid a salary from a U.S. company or otherwise engages in activity here that results in payment to the foreigner of a fee for services rendered here. Gray areas on this issue may become a problem for some business visitors in the B-1 category. It is best to consult directly with an immigration attorney to ensure that one remains in lawful status and does not violate federal immigration laws.
