The B-2 tourist visa is a non-immigrant visa that allows foreign nationals to visit the United States for tourism, vacation, or recreational purposes. It typically permits stays of up to six months, during which visitors can explore the country, visit family or friends, and engage in leisure activities. To apply for a B-2 visa, individuals must complete the DS-160 form, pay a visa application fee, and attend an interview at a U.S. embassy or consulate. Applicants must demonstrate their intent to return to their home country and provide evidence of sufficient funds to cover their stay in the U.S..
