Travel documents and entry requirements
The right documents decide whether you can board, transit and enter a country. Airlines check them at departure because they can be held responsible for passengers who are refused entry.
These guides explain the main document types in general terms. They are not legal or immigration advice. Requirements can change, always verify current rules with the relevant official authority before you travel.
