United Kingdom
- US Passport Holder: Eligible non-Europeans (including US citizens) visiting the UK will need an ETA (electronic travel authorization) from January 8, 2025.
- Non-US Passport Holder: If you hold a UK visa, you do not need an ETA. If your passport's issuing country allows visa-free travel to the UK, you will need to apply for an ETA.
