Visa Policy of the United States

The U.S. visa policy determines who can enter the country and under what conditions. Visitors typically need a visa or qualify for a visa waiver program, depending on their nationality and purpose of visit (e.g., tourism, business, study). Visa categories include nonimmigrant visas for temporary stays and immigrant visas for permanent residence. Applicants must meet specific requirements, such as demonstrating intent to return home or qualifying for waivers. The process involves submitting an application, attending an interview, and meeting security and eligibility criteria set by U.S. immigration laws.
