Mexico City Visa & Entry Requirements for US Visitors

US citizens do not need a visa to visit Mexico as tourists. A valid US passport is the only real requirement, and 180 days, the maximum allowed for tourism, is the standard stay granted at entry rather than something you have to ask for or qualify for. The part of this that trips up anyone who has been to Mexico before is the FMM, the tourist entry form visitors used to fill out by hand. For anyone flying in, that requirement is simply gone now, not just moved onto a screen.

What you need

A US passport book, not the passport card, since the card is not valid for international air travel. Mexico does not have an official rule requiring six months of validity beyond your trip, unlike many countries, but airlines and gate agents sometimes apply that rule anyway out of habit, so it is still worth renewing before a trip if your passport is getting close.

That passport is genuinely the only paperwork you need. No separate tourist visa exists for a standard US visit, and for anyone flying in, there is no entry form to complete either. The immigration officer at the counter reviews your passport and authorizes your stay, 180 days by default for tourism, though never guaranteed.

The FMM is not something you do anymore

Mexico used to require every visitor to fill out the FMM (Forma Migratoria Múltiple) by hand and keep the resulting slip loose in your passport for the length of your stay, then often hand it back on the way out. For anyone arriving by air, that is gone. The immigration officer processes your passport, and Mexico’s National Immigration Institute keeps the record electronically as the FMMd, a digital version of the same document. You never see it, fill it out, or carry it.

The FMMd is still a real record, and it is worth knowing it exists: if you ever need to prove a specific legal entry into Mexico, for something like a residency application years down the line, you can look up and download your own FMMd through the National Immigration Institute’s online portal. For an ordinary tourist trip, there is nothing to do with it and nothing to lose track of.

Benito Juárez Airport after the World Cup

Mexico City’s Benito Juárez International Airport (AICM) went through a real renovation ahead of hosting matches for the 2026 World Cup: terminal interiors, runways, taxiways, parking, and a large new camera and airport-management system, funded by several hundred million dollars in federal investment. Some of that work was still finishing after the tournament ended, but the terminals travelers pass through were the priority and were completed first.

Once you clear immigration, see Getting from Benito Juárez Airport (MEX) into Mexico City for the rest of the trip in.

The most relevant change for a US visitor is Viajero Confiable, a trusted-traveler program Mexico expanded specifically to cut down World Cup-driven bottlenecks at immigration. On paper, it requires enrolling in advance: an online application, then an in-person interview and biometric capture at a participating airport, before membership is approved.

What I have actually seen on the ground is a little different. Flying into Terminal 1, I have twice walked through a lane marked for US citizens, scanned my passport and face at a kiosk, and gone straight through, without ever having enrolled in anything. Whether that is a temporary expansion of the program for the World Cup or just how Terminal 1 works now, I do not know, but it has held up both times.

Terminal 2 has not caught up. The last time I came through there, during the World Cup and before Mexico’s final group-stage game, it was still the traditional process: a Federal Immigration Officer at a booth, checking passports one at a time. Which terminal you land in depends on your airline, so check your itinerary rather than assume.

On the stamp question: I used to have around 15 Mexican stamps stacked up in old passports. That is over now. Like most international airports at this point, Mexico has stopped stamping passports on arrival, and an officer will not do it even if you ask. Whatever record exists of your entry lives in the FMMd now, not in ink.

Language has not been an issue either way. Every time I have needed a word of English to clarify something, an officer has had enough to help.

Terminal 1’s line can look long from a distance, more people funneled toward the same handful of kiosks, but it moves fast because the process itself is quick. Terminal 2’s staffed line moves at the normal pace of one officer working one passport at a time, so a full flight landing at once there still means a real wait.

Take the government’s own pages on all of this as a starting point, not the final word. I have read the official rules for a program, then landed and found the actual process did not match what the website described, and found something different again the next time, at a different terminal of the same airport. Mexico’s immigration system is changing fast right now, and it is not changing at the same pace, or in the same way, at every airport, or apparently even at every terminal of the same one.
