Entry requirements and visas
Visa and entry rules depend on your nationality and change often, so Trip Rulebook does not summarise them. Each government explains the rules for its own citizens. If you travel on another passport, check with the embassy or the official immigration website of United Kingdom.
This page is guidance, not legal advice. Laws and advice change without notice and are written for each government's own citizens, so they may apply to you differently. Confirm everything with the official source before you travel. Terms of use.
