B-1 visas are usually issued to aliens who are coming to the
United States to enter into or negotiate
contracts, purchase goods for shipment abroad, obtain orders for products
manufactured abroad, attend business conventions, consult with business
organizations, or to investigate business opportunities in the United States.
They may also be used to check on business investments that the alien has
previously made in the United States,
and to permit the alien to open and establish a new US business, although, it must be
pointed out that, the alien cannot actively participate in the management of
said business.
