US passport holders can visit many countries visa-free, but a growing number require an electronic travel authorization, like the UK ETA, an eVisa applied for online, or a traditional visa from an embassy. Requirements depend on your destination, trip purpose, and length of stay. Check the State Department’s country page and the destination’s official government site before you book.

What’s the difference between a visa, an eVisa, and a travel authorization?
These terms describe different levels of pre-approval. Knowing which one applies tells you how far ahead to start.
- Visa-free: enter with just your passport, as in the Schengen Area, Mexico, Japan, and South Africa for typical tourist stays
- Electronic travel authorization: a quick online pre-clearance, such as the UK ETA, Kenya’s eTA, or Australia’s ETA
- eVisa: a visa applied for and issued online, as for India or Vietnam; Brazil reinstated an eVisa requirement for US citizens in April 2025
- Visa on arrival: issued at the airport, in some countries
- Consular visa: applied for through an embassy or consulate, often with documents and an appointment
How do you check entry requirements for your destination?
Start with the State Department’s country information page for each country on your itinerary, including places where you’ll connect. It lists passport validity, blank page requirements, visa rules, and required vaccinations. Then confirm with the destination’s official government or embassy site, since rules can change quickly.
Purpose matters. A visa-free entry for tourism may not cover paid work, and some business activities need a different visa.
How far ahead should you apply for a visa?
Electronic authorizations are often approved within days, but don’t leave them to the last minute. Embassy visas can take weeks or longer and may require appointments.
Watch timing in the other direction too. Some visas become valid from the date they’re issued, so applying too early can shorten your usable window. Build documents into your planning timeline.
Which popular destinations need something extra?
Requirements change, so treat these as starting points to verify, not final answers.
- Europe: visa-free for up to 90 days in 180 under the Schengen rule; ETIAS isn’t operating yet
- United Kingdom: ETA required since January 2025
- Kenya: an electronic travel authorization is required before arrival; see Kenya
- Tanzania: a visa is required and can be applied for online
- French Polynesia: visa-free for most US tourist stays; see entry requirements
- South Africa: visa-free for tourist stays, but plan for blank passport pages
How do you avoid visa scams and costly mistakes?
Apply through official government websites or apps, which usually end in .gov or the country’s official domain. Many look-alike sites charge extra fees, and some never submit your application.
Make sure every application matches your passport exactly, including your full name and passport number. If you renew your passport, check whether existing authorizations transfer; many don’t. Don’t confuse these systems with the US ESTA, which is for foreign visitors to the United States.
