A tourist visa is an official document or stamp in a passport that allows a traveler to visit a foreign country for leisure, sightseeing, or recreational purposes for a limited period, typically ranging from a few days to several months. It does not permit the holder to engage in work or long-term studies. Some countries offer visa-on-arrival or visa-free entry to certain nationalities, while others require an application and approval before travel.

A business visa is a type of travel authorization that allows foreign nationals to enter a country for the purpose of conducting business activities, such as meetings, conferences, negotiations, or establishing partnerships. This visa is typically granted for a specific period and does not permit the holder to engage in employment or long-term residency.

A student visa is a type of visa that allows foreign nationals to enter and stay in a country for the purpose of studying at an accredited educational institution. The requirements for obtaining a student visa vary by country but generally include proof of admission to a recognized school, sufficient financial resources to support oneself during studies, and the intention to return to one's home country after the program ends.

A transit visa is a temporary, short-term visa issued to travelers who are passing through a country on their way to another destination. It allows the holder to stay in the country for a limited time, typically ranging from a few hours to a few days, depending on the country's regulations. Transit visas are often required if the traveler needs to leave the airport or transit through immigration.

A residence visa is an official document or permit that allows a foreign individual to live in a country for an extended period, usually beyond the duration allowed by a tourist or business visa. It is often issued for purposes such as employment, education, family reunification, or retirement and may come with specific conditions, such as maintaining a job or enrolling in an educational institution.

A diplomatic visa is a type of visa issued to individuals representing their home country in an official capacity, such as diplomats, consular officers, or government officials on assignment abroad. It grants privileges and immunities under international law, including exemption from certain taxes, customs duties, and legal jurisdiction in the host country.
