The 90/180 rule for US citizens: how long you can stay in Europe

How long can US citizens stay in Europe?

US citizens can spend at most 90 days within any 180-day period in the Schengen area without a visa, for tourism or business. The 180 days form a rolling window, not a calendar block: on any day of your stay, look back 180 days and count your days of presence, and that count must never exceed 90. Both the day you land and the day you fly out count in full.

The rolling window is the part Americans most often get wrong. There is no reset date, no new allowance in January, and leaving the area does not wipe the slate. A day spent in Europe keeps counting against you for a full 180 days after it happened, then quietly drops out of the window. The State Department's Europe travel page states the rule and adds a practical warning: officials will assume you intend to stay past the limit if you cannot show an onward or return ticket.

Enforcement stopped depending on passport stamps in 2026. Since 10 April 2026, the EU Entry/Exit System (EES) has logged every entry and exit at every Schengen border against your passport, with a facial image and fingerprints taken at first registration. The day arithmetic is now done by a computer, and an overstay of one day is as visible as an overstay of thirty. Our overstay consequences guide covers what happens when the count goes wrong.

Is it 90 days per country or for all of Europe?

One shared allowance for the whole Schengen area. Days in Italy, France, Germany and the other 26 member states all draw from the same 90-day budget. Crossing from Italy into France does not start a new count, because there is no border control between them and no separate allowance waiting on the other side.

So a spring itinerary of four weeks in Italy, four in France and four in Spain is not three separate month-long visits. It is 84 days against a single 90-day cap, leaving six days for the rest of the window. The area also does not match the EU: non-EU Switzerland, Norway and Iceland are Schengen members and count toward your 90, while EU member Ireland sits outside the system entirely.

Do Americans need a visa or ETIAS for Europe?

No visa for stays within the 90/180 limit, and as of July 2026 no pre-travel authorization either. That second part changes soon: ETIAS, the EU's online travel authorization, is expected to start in the last quarter of 2026. Once it is live, Americans will apply online before travel, pay 20 euros (free under 18 and over 70), and receive an authorization valid for up to three years or until the passport expires.

ETIAS does not change the day math. The limit stays at 90 days in any 180, counted the same way, and the authorization is a screening step rather than a longer permission to stay. The details, including the planned transitional period, are in our ETIAS guide.

Can Americans stay in Europe for 6 months?

Not visa-free, and not by hopping between Schengen countries. Six months is roughly 182 days, double the 90-day allowance. The legal routes are a national long-stay visa from one country, or splitting the year so that no 180-day window ever contains more than 90 Schengen days, which caps you at about half the year in two separate blocks.

The long-stay visas are national, which surprises applicants in two ways. A French long-stay visa lets you live in France, but your travel to the rest of the Schengen area remains capped at 90/180. And living somewhere most of the year has tax consequences: cross 183 days in one country and you are generally tax resident there, a threshold our 183-day rule guide explains. The three most used routes for Americans:

Each is a paperwork project measured in months, not a form at the airport. Budget for consulate appointments, FBI background checks with apostilles, and proof of accommodation before you book anything nonrefundable.

Do trips to Ireland count toward the 90 days?

No. Ireland is in the EU but not in the Schengen area, so Irish days never touch your Schengen count. Ireland runs its own rule for Americans: up to 90 days visa-free per visit, granted by the immigration officer on arrival, entirely separate from anything you did in continental Europe.

The same goes for the UK, which allows US visitors up to six months, and for non-Schengen countries like Albania, Serbia and Turkey. Long-stay travelers use these as waiting rooms: burn through 90 Schengen days, then let the window age out from Dublin, London or Istanbul instead of flying home. Just remember each of those countries counts its own days under its own rules.

Two worked examples with real 2026 dates

This is the failure mode of manual counting: no single trip looks wrong, and the total only exists inside a 180-day window nobody is watching. Staydays watches it. The app logs which country you are in each day using low-power background location, recalculates the rolling window daily, and warns you before you approach 90. The log stays on your iPhone and in your private iCloud.
