Mexico Visa and Entry Requirements

The short version

Your passport must be valid for the duration of your stay. The Mexican embassy recommends at least 180 days of validity, because 180 days is the longest a tourist may be given. On arrival you are stamped with the number of days you are allowed, and that number is set by the officer.

The one thing this guide does not tell you

What a United States passport holder must hold in order to enter Mexico for tourism is deliberately absent from this page. The source cached for this cluster is written for a different nationality, the requirement is Mexico's to set and it has changed, and a guess here would be the one error on these sixteen pages capable of sending somebody to an airport without a document.

Confirm it with the Mexican consulate responsible for your state, close to travel, and confirm it again if your trip is for any purpose other than tourism. Everything else on this page applies regardless of where your passport was issued.

The stamp, and why it matters more than the rule

This is the part that catches people, and it catches them on the way out rather than on the way in. The permission is up to 180 days. The officer writes a number, and it is frequently 30, 60 or 90 rather than the maximum.

So: look at your stamp before you leave the immigration hall, read the number, and plan the trip around that rather than around the ceiling. If you are staying a long time, or working remotely, or leaving and re-entering, the difference is the difference between a clean exit and an overstay.

Keep the stamp. The authorities can ask to see your passport and the entry stamp at any time, and they do not accept a copy or a photograph of either. There is a digital registry of entry documents through the national immigration portal, which is worth retrieving in the first days.

Passport validity

The requirement is validity for the length of your stay, which is looser than the six month rule most countries apply. Two cautions follow from that rather than from Mexico:

• If you transit another country on the way there or back, that country's rule applies to you as well, and many require six months of validity.
• A passport with only a few months left is a poor traveling companion regardless of what the minimum permits.

Arriving by land

Land entry involves an immigration form completed online rather than on paper, and the requirement differs by nationality, so check which applies to you before you reach the crossing. Get the stamp, and check the number on it, exactly as you would at an airport.

What a tourist may not do

This section is longer than it looks because Mexico draws the line in an unusual place.

• No voluntary or paid work of any kind. That includes unpaid volunteering and it explicitly includes human rights work. Doing it requires the correct visa, obtained before travel.
• Some adventure and ecotourism activities may need a visa, specifically where they touch on scientific or technological research. Caving, potholing and entomology are named. The Mexican authorities define research far more broadly than most countries do, so an activity that feels like a hobby at home can be caught.

If any of that is close to your plans, ask the consulate well before you travel and ask for the answer in writing. That is the source's own advice and it is worth following literally.

Traveling with a minor

Rules for a child traveling without both parents are set by Mexico and applied strictly across the region. If a child on your booking is not traveling with both legal guardians, confirm the exact documentation with the consulate before you book.

A short checklist

• Passport valid for the whole stay, and comfortably longer if you transit anywhere.
• Visa position confirmed with the consulate for your nationality and your purpose.
• Land entry form completed in advance if you are crossing by road.
• The number on your stamp read and noted before you leave the hall.
• Passport and stamp carried, not copied.
• Written confirmation from the consulate if your trip involves anything that could be called research.

Verify before you travel

Entry rules, forms and the online systems that administer them change. Confirm the current position with the Mexican consulate close to departure.
