The short version
The Spanish authorities set and enforce entry rules, and Spain follows Schengen area rules. For a short visit as a tourist, to see family or friends, to attend business meetings or a cultural or sporting event, or for short-term study or training, many nationalities including United States citizens travel without a visa.
The limit is up to 90 days in any 180-day period, and the sentence that matters more than any other on this page is the one about arithmetic.
The ninety days are not Spanish
They belong to the Schengen area as a whole. If your trip also touches France, Portugal, Italy, Germany, the Netherlands or any other Schengen country, the whole visit has to fit inside the same allowance. Visits to Schengen countries in the 180 days before you travel count toward it as well, which catches people who were in Europe earlier in the year and think of this trip as starting from zero.
Overstaying is not a paperwork problem. You may be banned from entering Schengen countries for up to three years. If you need to extend a visa-free stay for an exceptional reason such as a medical emergency, you must apply to the immigration authorities, the Extranjeria, rather than simply staying.
Passport validity, and whose rule it is
⚠ The two tests below come from the UK advisory and are written for British citizens. They describe how Schengen border control treats a third-country passport, so an American reader should expect the same shape of check and confirm their own position with the Spanish authorities or the nearest Spanish consulate.
Under Schengen area rules, the FCDO says a passport must have a date of issue less than ten years before the date you arrive, and an expiry date at least three months after the day you plan to leave the Schengen area. The expiry date does not itself need to fall within ten years of the date of issue. You will be refused entry without a valid travel document, or with a passport that has been reported lost or stolen.
The practical version: look at both dates on your passport, not just the expiry. A passport renewed early can carry extra months and a date of issue further back than you expect.
What a border officer may ask to see
At Spanish border control you may need to show a return or onward ticket, proof of travel insurance, that you have enough money for your stay, and where you are staying. The amount of money is not fixed: the advisory says it varies depending on your accommodation. Where you are staying can mean a hotel booking confirmation, proof of address if it is your own property, or an invitation and proof of address if you are staying with friends or family, which in Spain is often a carta de invitacion completed by your hosts.
None of this is usually asked for. All of it is occasionally asked for, and the cost of having it on your phone is nothing.
Stamps and e-gates
Use the desks staffed by border officers. If you are eighteen or over and staff direct you to an e-gate, you may be able to use one when they are working. If you use an e-gate, make sure you get your passport stamped. The stamps are the evidence of when your days were used, and an unstamped entry is a problem you discover at the exit rather than at the entrance.
Staying longer, and working
To stay beyond the ninety days you must meet the Spanish entry requirements for whatever you are actually doing, which means applying for the right visa or permit before you travel. The requirements for working in Spain are different from those for visiting, and a business meeting is not work in this sense. This is a question for the Spanish consulate responsible for where you live, and it is worth asking early: consular appointments are the slowest part of most plans.
Bringing things in
There are strict rules about what may be taken into and out of Spain, and anything prohibited or subject to tax or duty has to be declared. You cannot take meat, milk or products containing them into European Union countries, with narrow exceptions such as powdered baby milk, baby food and special foods or pet feed required for medical reasons. That rule catches more American travelers than any other, usually in the form of a sandwich.
Declare cash or traveler's checks worth 10,000 euros or more. You will be given a certified declaration showing you brought it in, and without one your money could be seized when you leave. Our money guide covers what to carry and what to pay with.
If it goes wrong
If your passport is lost or stolen in Spain you must renew it or apply for an emergency travel document. You cannot use a police report to leave the country. Report the theft anyway, because your insurer will need it, and read our safety guide for how the theft usually happens.
