Entry at a Glance
Step-by-Step Arrival Walkthrough
Complete Your FMM (Forma Migratoria Múltiple)
Complete the FMM online at inm.gob.mx before you fly, or fill in the paper form distributed on the plane. The online version saves 15–20 minutes at the immigration queue. Print the confirmation or save it on your phone.
Immigration Queue
Join the international arrivals queue at MEX. Have your passport and completed FMM ready. Queues at MEX move faster than most comparable airports – typically 10–20 minutes during off-peak hours.
Immigration Stamp – Keep Your FMM
The officer stamps your passport and returns half of your FMM. Keep this document for the duration of your stay. You will need to surrender it when you exit Mexico. Losing it results in a fine and delays at departure.
Luggage Collection
Collect your baggage from the carousel. Belt numbers are displayed on screens throughout the arrivals hall. MEX has reliable baggage handling – typical wait is 15–20 minutes after landing.
Customs Declaration – Red/Green Light
Mexico uses a random-button customs system. Press the button: green means proceed, red means your bags are screened. Most travellers with personal dental/medical items get through on green. Declare any amounts over US$10,000 in cash.
Arrivals Hall – Collect Your Ride
You are through. Proceed to the arrivals hall. Book your Uber or Didi now using the terminal Wi-Fi, or go directly to the Taxi Autorizado desk on the left side of the hall. Polanco is 25 minutes away.
Complete Your FMM Online Before You Fly
The FMM can be completed online at inm.gob.mx. This is free and saves 15–20 minutes at immigration. Print or save the QR code on your phone. Many travellers skip this step and regret it after a long flight.
The form takes about 3 minutes to fill in. You will need your passport number, flight details, and your accommodation address in Mexico City.
For Longer Treatment Plans
Mexico grants up to 180 days on a single tourist entry – no extension process required. For a full-mouth reconstruction that requires 2–3 visits over several weeks, this single entry covers you completely.
The date stamped on your FMM is your exit deadline. Exit Mexico on or before that date. Overstaying is technically possible to resolve (a fine is paid at the airport), but it creates stress and delays at departure. Simply plan your return flight inside your 180-day window.
Do not overstay your FMM date. Even if the fine is manageable, overstaying creates a record and may affect future Mexican entry applications.
Health Note: Mexico City Altitude
Mexico City sits at 2,240 metres (7,349 feet) above sea level – higher than most cities patients travel from. Some visitors experience mild altitude sickness for the first 24–48 hours: light headaches, fatigue, or slight breathlessness. This is common and resolves quickly.
- ✓ Stay well hydrated – altitude increases fluid loss
- ✓ Avoid strenuous activity on Day 1
- ✓ Limit alcohol for the first 24 hours
- ✓ Most dental procedures can proceed normally once you have acclimatised
- ⚠ If you have cardiovascular or respiratory conditions, discuss the altitude with your dentist before travel
