The B-1 visa is a temporary visa for business visits to the United States. It lets you enter the U.S. briefly for activities such as meeting with business associates, consulting with clients, attending conferences, negotiating contracts, or receiving short-term training. You are not allowed to take a regular job or work for a U.S. company under the B-1 visa. It is considered a non-immigrant visa, meaning you must have a home abroad that you intend to return to after your trip. Typically, B-1 visitors can stay in the U.S. for up to six months per trip (and in some cases, you may apply to extend that up to a year total). The B-1 is ideal if you need to be in the U.S. for work-related reasons without moving here long term.
