What this means
Electronic travel authorizations (like the US ESTA, Canadian eTA, or UK ETA) are filled out online in minutes, usually approved within hours, and typically stay valid for multiple trips over several years. Airlines check for one at check-in, so apply before you head to the airport.
Apply only on the destination's official government site — lookalike third-party sites charge large markups for the same form. An approved authorization still doesn't guarantee entry; the border officer makes the final decision.
Before you travel
- Passport validity: many countries require your passport to be valid 3–6 months beyond your stay, with at least one blank page.
- Border officers can ask for a return or onward ticket, accommodation details, and proof of funds — have them reachable.
- Apply on the official government portal only, and carry a printed or offline copy of the approval.
- These rules cover short tourist/business visits on an ordinary passport. Work, study, residence, journalism, and diplomatic travel follow different rules.
- Connecting through another country? Check that country's transit rules separately.
