U.S. citizens don’t need a visa to visit Mexico for tourism, and stays of up to 180 days are allowed. What you do need depends on one question: how are you getting there? A flight to Cancún, a drive to San Felipe, a cruise stop in Cozumel, and a walk across the bridge into Tijuana each come with different paperwork, and the return trip has its own rules on the U.S. side.
Flying to Mexico
This is the simplest route, and the one with the least flexibility.
What you need:
- A U.S. passport book. A passport card is not valid for international flights. Make sure it’s valid for your entire stay; many airlines prefer at least six months of validity, so renew early if yours is close.
- The FMM tourist permit, which for air travelers is handled for you. The 2026 fee of 983 Mexican pesos (roughly $55) is built into your airfare, and at Mexico’s busiest airports the permit is now digital: the officer records your entry, stamps your passport, and writes or enters the number of days you’re allowed to stay.
- A return or onward ticket and your hotel details, in case the immigration officer asks.
Look at the stamp before you walk away from the counter. The officer decides how many days you get, and it isn’t always the full 180. If you were given fewer days than your trip requires, ask right there.
If your passport is expired or about to be, start with our passport renewal checklist. First-timers need the full passport application documents.
The extra fee in Cancún and the Riviera Maya
If you’re staying in Quintana Roo (Cancún, Playa del Carmen, Tulum, Cozumel, Isla Mujeres), the state charges a separate tourist fee called Visitax. It’s paid online through the state’s official site, and some travelers have been asked for the receipt at the airport on departure. It isn’t the same as the FMM, and paying one doesn’t cover the other.
Driving Into Mexico
Driving is where the paperwork stacks up, because both you and your car need permission to be there.
Step 1: Your own entry documents
- A U.S. passport book or passport card. The card works for land crossings.
- An FMM, which you get from the INM (immigration) office at the crossing or start online before you go. Don’t drive past the immigration office without stopping; at many crossings, no one waves you over.
Short land visits of seven days or less generally don’t carry a fee. Longer stays pay the same FMM fee air travelers pay. Our Mexico FMM tourist permit guide walks through the online form and what to print.
Step 2: The car’s permit
Whether your car needs a Temporary Vehicle Import Permit (TIP) depends on where you’re going:
| Destination | TIP needed? |
| The border zone, roughly the first 20 to 30 km past the border | No |
| Anywhere on the Baja California peninsula | No |
| The “Sonora Only” corridor in northern Sonora | No, under that program’s rules |
| Mainland Mexico beyond the border zone | Yes |
To get a TIP from Banjercito, Mexico’s military bank that handles vehicle permits, bring:
- Your passport and FMM
- The vehicle’s title or current registration in your name
- Your driver’s license
- A letter from the lender authorizing the trip if the car is financed or leased
- A credit card in the vehicle owner’s name for the fee and refundable deposit
Expect to pay a permit fee of around $50 plus a deposit that typically runs a few hundred dollars depending on the vehicle’s age. You get the deposit back only if you cancel the TIP when you leave Mexico, so stop at the Banjercito window on your way out. If your title or registration has an old address or name, fix it first with the car registration documents checklist.
Step 3: Mexican auto insurance
Most U.S. auto policies don’t cover you in Mexico, and Mexican law requires liability coverage from a Mexican insurer. Buy a policy before you cross and keep the printed proof in the car.
More detail on border crossings by car is in our guide on whether you need a passport to drive to Mexico.
Walking Across or Day-Tripping
For a few hours in Tijuana, Nogales, or Ciudad Juárez, you’ll typically walk into the border zone without being asked for an FMM. You still need a passport book, passport card, or other approved document to come back into the U.S., and that’s the part people forget. A driver’s license and birth certificate alone won’t get an adult back through a U.S. land port.
Arriving by Cruise Ship
On most cruises, the cruise line handles Mexican immigration for passengers on the ship, so you won’t fill out an FMM for a day in Cozumel or Ensenada. Your documents are set by the cruise itself. On a closed-loop cruise that starts and ends at the same U.S. port, U.S. citizens can often sail with a certified birth certificate and a government photo ID instead of a passport. Our guides to cruise passport requirements and the closed-loop cruise birth certificate rule explain when that works and when it’s risky.
Coming Back to the U.S.
| How you return | Adults (U.S. citizens) | Children under 16 (U.S. citizens) |
| By air | Passport book | Passport book |
| By land or sea | Passport book, passport card, Enhanced Driver’s License, or a trusted traveler card (NEXUS, SENTRI, Global Entry) | Certified birth certificate, or any of the adult documents |
Teens under 19 traveling with an organized school, religious, or youth group can also use a birth certificate at land and sea crossings. Green card holders should carry a valid card; if yours has expired and you’re waiting on a renewal, see traveling with an expired green card before you leave.
Traveling With Kids
Mexico’s strict exit-permit rules apply to Mexican citizen children, but U.S. kids also get questioned, especially when only one parent is present or the child is traveling with grandparents, a coach, or friends. A notarized consent letter from the absent parent (or both parents) is the simplest way to avoid trouble with an airline or immigration officer. Our notarized child travel consent letter guide includes what to put in it, and one parent traveling abroad with a child covers custody papers and passport consent.
Bringing Your Dog or Cat
Mexico’s rules for pets are relatively light: dogs and cats typically need to look healthy on arrival and be free of parasites, and some travelers carry a recent vet certificate and rabies record to avoid questions. The harder part is coming home. The CDC’s dog import rules apply to dogs returning to the U.S., including U.S.-born dogs that visited Mexico. Start with taking a dog to Mexico, check the Mexico pet import requirements, and read bringing a dog back from Mexico before you book.
Before You Go: A Short Checklist
- ☐ Passport book (air) or book or card (land and sea), valid for the whole trip
- ☐ FMM, either included in your airfare or completed at or before the land crossing
- ☐ Visitax receipt if you’re staying in Quintana Roo
- ☐ TIP, title or registration, lender letter, and Mexican insurance if you’re driving into the mainland
- ☐ Consent letter and birth certificates for children traveling without both parents
- ☐ A photocopy or phone photo of your passport, stored separately from the original
Questions Travelers Ask
- Can I enter Mexico with just a birth certificate? Not as an adult, except on many closed-loop cruises where the cruise line’s rules apply. By air or by land, you need a passport book or card.
- What if I lose my FMM or passport in Mexico? Contact the nearest U.S. consulate for a replacement passport, then visit an INM office to deal with the FMM before you leave. Losing the permit can lead to a fine at departure.
- Can I stay longer than my FMM allows? Not as a tourist. Overstaying can bring fines and trouble at exit. If you plan a long stay, ask the officer for enough days at entry.
- Do I need travel insurance? It isn’t required for entry, but U.S. health insurance often doesn’t cover care in Mexico, and medical evacuation is expensive.
- Is the passport card enough for a road trip to Baja? Yes, for crossing the border and entering by land. You’ll still need an FMM if you go beyond the border zone or stay more than a short visit.
- Will immigration ask how much money I have? Usually not, but officers can ask about your plans, where you’re staying, and how you’ll support yourself. Keep your hotel confirmation, return ticket, and a credit card or bank card handy. Vague answers are what lead to shorter stays or secondary questioning.
