A tourist or visitor visa is an official document or electronic authorization granted by a country that allows international travelers to enter temporarily for leisure, holidays, business meetings, or family visits.

Generally, you need a passport valid for at least 6 months, recent passport-sized photos, visa application forms, proof of sufficient funds (bank statement), a detailed travel itinerary, hotel bookings, and professional proof (job certificate or trade license).

Processing times vary depending on the country. Some countries issue e-visas within 3 to 7 working days, while major destinations like the USA, UK, Canada, or Schengen countries can take anywhere from 2 weeks to a few months.

The best way to avoid rejection is by providing 100% genuine documents, showing strong financial capability to support your trip, and demonstrating solid professional or personal ties to your home country to prove you will return after your tour.
