Most popular destinations let U.S. citizens stay 90 days visa-free — but limits vary widely: Mexico gives 180 days, the UK and Canada 6 months, Georgia a full year, while Schengen Europe counts 90 days per 180-day period across ALL its countries combined. Some destinations (China, India, Brazil, Russia, Nigeria) require a visa before travel.
The big picture
Your U.S. passport opens ~180+ destinations visa-free or with visa-on-arrival — but 'visa-free' never means 'stay forever'. Every country sets a maximum, and overstaying gets you fined, deported, or banned from re-entry.
Stay limits for top destinations

The Schengen trap
The 90/180 rule is where Americans most often overstay without realizing: your 90 days count across ALL Schengen countries together — a month in France + a month in Italy + a month in Spain = you must leave for 90 days. Use our Schengen rule guide to calculate your exact allowance.

How the clock actually works
- Per entry: count resets when you leave (Mexico, Japan, most countries)
- Rolling window: Schengen 90/180, Kazakhstan 90/180 — count backward from today
- Calendar-based: Nepal caps at 150 days per calendar year, Colombia 180/year
- Extensions: some countries let you extend locally (Thailand +30, Nepal up to 150 days) — always extend BEFORE expiry
Overstay consequences
Fines at exit are the gentle version. Schengen overstays can mean an entry ban recorded in SIS (the shared database); Japan and Korea flag overstays for future denials; Thailand stamps 'overstay' in your passport. A one-day accidental overstay is usually a fine — a three-month one is a ban.
