B-1: Visitor for business purposes coming to the U.S. on a short trip for a foreign employer. Typically, an individual’s initial admission in this status is limited to a maximum of six months. This visa status does not normally authorize an individual to work for a U.S. employer. The U.S. has implemented a visa waiver program that enables foreign nationals of many countries to enter the U.S. under B-1 status without obtaining a visa in advance.
B-2: Temporary visitor for pleasure (tourist). The visa waiver program available to nationals of certain countries also applies to the B-2 visa category.
