A USA Visitor Visa is a document that allows foreign nationals to travel to the United States for tourism, medical treatment, business, or other temporary purposes. Also known as a B-2 visa, it is issued by the US Department of State and grants permission to stay in the US for up to six months. To obtain a visitor visa, applicants must demonstrate that they have strong ties to their home country, such as a job, property, or family, and that they have the financial means to support their trip to the US. They must also show that they intend to return to their home country after their visit and that they do not pose a security risk. The application process includes submitting a completed form and attending an interview at a US embassy or consulate in their home country. Once granted, visitors are allowed to enter the US and travel within the country for tourism or business purposes.
