A tourist visa is a type of travel document that allows individuals to enter a foreign country for leisure or vacation purposes. It typically permits a stay for a limited duration, often ranging from a few weeks to several months, depending on the country's regulations. Tourists must apply for this visa before their trip, providing necessary documentation such as a valid passport, travel itinerary, and proof of accommodation. Obtaining a tourist visa usually involves filling out an application form and paying a fee. Some countries may require an interview or additional documentation, while others offer visa-on-arrival options. It is essential for travelers to check the specific requirements of their destination country to ensure a smooth entry.
