U.S. Citizens Traveling Abroad: The Complete Guide to Visas, Trusted Traveler Programs, Emergencies, and More

Planning an international trip as a U.S. citizen involves a lot more than just booking a flight and packing a suitcase. From figuring out whether you need a visa, to deciding if TSA PreCheck or Global Entry is worth the investment, to knowing exactly who to call if something goes wrong overseas — there's a surprising amount to keep track of before you head to the airport.

This guide brings together everything U.S. citizens need to know about traveling abroad, with links to detailed breakdowns on each topic so you can dive deeper into whatever applies to your trip.

Do You Need an International Driving Permit?
