Mexico Visa Information
British citizens need a tourist card rather than a visa to visit Mexico. You can obtain this on arrival by filling out an immigration form available at border crossings or on-board flights to Mexico. Before being allowed entry, you may have to provide immigration officials with proof of your departure plans, but this is not a formal entry requirement.
Passport Validity for Mexico Travel
Your passport should be valid for the entirety of your stay in Mexico and it should have at least one blank page. For further information, please check with the embassy.
