A tourist visa is an official document or stamp in your passport that allows you to enter a foreign country for leisure, sightseeing, and travel purposes. Typically, it does not permit you to engage in business or employment activities. The application process usually involves filling out a form, providing a valid passport, passport-sized photos, proof of travel plans, financial stability, and possibly an invitation letter. Processing times and fees vary by country. It’s important to check the specific requirements of the country you plan to visit.
