The 3 Types of Visa Situations
1. Visa-Free Entry
Some countries allow passport holders from specific nations to enter without any prior visa. US passport holders can enter over 186 countries visa-free as of 2026.
2. Visa on Arrival
You obtain the visa upon landing. Thailand, Cambodia, Egypt, and Jordan commonly offer this. Always carry some USD cash for the fee.
3. Visa Required in Advance
You must apply before you travel. Countries like China, India, Russia, and the US require advance visas. Missing this step means a missed trip.
Europe: ETIAS
The Schengen Zone covers 29 countries. US, Canada, Australia, and UK can enter visa-free for 90 days. The ETIAS pre-travel authorization costs 7 euros and is valid 3 years. Check your requirements here.
