Whether you need a visa depends on your nationality, the country you are visiting, the length of your stay, and the purpose of your trip.
Visa requirements vary between countries. It is your responsibility as the traveler to check if a visa is required for your destination, any transit countries, and for your return.
We recommend visiting the official website of the embassy or consulate of the country you are traveling to. There you will find the most accurate and up-to-date information based on your personal travel details.
Make sure to check this well in advance of your departure, as visa processing times can vary.
