If you're visiting Mexico, you'll need an FMM — the Forma Migratoria Multiple. It's not technically a visa, but it's Mexico's official immigration form that authorizes your stay. Whether you're flying in for a vacation or driving across the border, here's what you need to know in 2026.
What Is the FMM?
The FMM (Forma Migratoria Multiple) is Mexico's immigration form for visitors. Think of it as your tourist card — it records your entry, your authorized number of days, and must be returned when you leave. It applies to all visitors, regardless of nationality, including visa-free travelers.
Key fact: The FMM is not a visa. Visa-free nationals (US, Canada, EU, etc.) still need an FMM. It's Mexico's way of tracking entries and exits.
FMM Cost in 2026
The FMM fee in 2026 is 983 MXN (approximately $57 USD).
- Air travelers: The fee is typically included in your airline ticket price. You may not even notice it.
- Land border crossers: You must pay at the border crossing if traveling beyond the free border zone (typically 20-30 km from the border). Short trips within the border zone don't require an FMM.
- Cruise passengers: Generally exempt for stays under 72 hours in port.
How to Get an FMM
Flying Into Mexico
Many airlines now process the FMM electronically. You may receive a digital confirmation via email or your airline's app. Some airports still distribute physical cards on the plane or at immigration. Either way, the process happens at the immigration checkpoint when you land.
Driving or Walking Across the Border
If you're crossing the US-Mexico land border and plan to travel beyond the border zone:
- Stop at the INM (immigration) office at the border crossing
- Fill out the FMM form
- Pay the 983 MXN fee at a nearby bank (Banjercito is usually on-site)
- Get your form stamped
- Keep it safe — you'll need it when you leave
Online Pre-Registration
Mexico's INM offers an online pre-registration system where you can fill out the form before arrival. This speeds up the process at the airport or border but doesn't replace the in-person verification.
How Many Days Will I Get?
The maximum stay for tourists is 180 days. However, the immigration officer at the point of entry decides how many days to grant you. Common scenarios:
- Air arrivals: Usually get the full 180 days
- Land border: Officers sometimes give 30, 60, or 90 days depending on your explanation
- Frequent visitors: May get fewer days if officers suspect you're living in Mexico on tourist status
Always check: Look at the number of days written or stamped on your FMM. Don't assume you got 180 days. If you got fewer than you need, ask the officer to reconsider — once you walk away, it's done.
Can I Extend My FMM?
No. The FMM cannot be extended once issued. If you need to stay longer than the days granted, your options are:
- Leave and re-enter: Exit Mexico (fly to another country, cross a border) and get a new FMM upon return. This resets your days but immigration may give you fewer days on re-entry.
- Apply for residency: Before your FMM expires, you can apply for a change of status to temporary residency at an INM office. This is the proper legal route if you want to stay long-term.
What Happens If I Overstay?
Overstaying your FMM has consequences:
- Fine at departure: 600-700 MXN ($35-$40 USD) at the airport
- Delays: You may be held at the airport while the fine is processed
- Serious overstays: Long overstays can result in detention, deportation, or a ban from re-entering Mexico
- Future problems: Immigration officers may flag you and give fewer days on future visits
Lost Your FMM?
If you lose your physical FMM card:
- Visit the nearest INM office before your departure
- Bring your passport and a copy of your FMM (if available)
- Pay a replacement fee
- Get a new FMM issued for your departure
This is important — without an FMM, you'll have problems at the airport. Don't wait until the last minute.
FMM vs. Residency Visa: When to Upgrade
If you're spending more than a few months a year in Mexico, it's worth getting a residency visa instead of relying on the FMM. Benefits include:
- No more worrying about 180-day limits
- Open a Mexican bank account
- Get an RFC (tax ID) for property rental or business
- Access IMSS healthcare
- Build toward permanent residency and citizenship
