Quick answer
Do you need a passport to go to Mexico? It depends on how you travel. If you fly, yes: every US citizen needs a valid passport book, and a passport card cannot be used to board a plane. By land, US authorities accept a passport book or a passport card, but Mexico's immigration institute says the card covers only the land crossing and the border zone. On a closed-loop cruise that starts and ends at the same US port, a birth certificate plus a government photo ID is accepted for travelers 16 and older. US citizens do not need a visa for tourist stays of up to 180 days, but most visitors get an FMM entry permit, now digital at airports. Mexico has no six-month passport rule. If you stay in Quintana Roo, which includes Cancun and Tulum, the Visitax tourist tax is mandatory.

Do you need a passport to go to Mexico: the answer by trip type
The short answer is that it depends on how you cross the border. Mexico checks your documents at the airport, at the land border and at the cruise pier, and each one has its own rules.
Flying is the strictest case. Every US citizen on a flight to Mexico needs a passport book, and that includes babies and children.
The wallet-sized passport card is not accepted for air travel.
Driving or walking across the land border is looser. US authorities accept a passport book or a passport card as proof of citizenship. Mexico's immigration institute, the INM, says the card covers only land crossings and the border zone, so bring the book if you are going farther.
Cruises are the loosest of all, but only for one kind of cruise. If your ship leaves from a US port and returns to the same port, a birth certificate can stand in for a passport.
Which document you need, by route
| How you travel | Passport book | Passport card | Other accepted documents |
|---|---|---|---|
| Flight to any Mexican airport | Required | Not accepted | None |
| Driving or walking across the land border | Accepted | Accepted by US authorities; Mexico's INM limits it to the border zone | None for entry to Mexico |
| Cruise or other sea travel | Accepted | Accepted | NEXUS, SENTRI or FAST card, or a state-issued REAL ID |
| Closed-loop cruise from a US port | Accepted | Accepted | Birth certificate with raised seal, plus photo ID if 16 or older |

One more rule applies to every route. Mexican authorities may deny entry to people with a criminal history or pending charges, so a valid document alone does not guarantee you get in.
When you need a passport to go to Mexico by air, land or sea
People ask the same question in many ways. Do I need a passport to go to Mexico? Do you need a passport to go to Cancun, Mexico, or to Cabo or Cozumel?
Do US citizens need a passport to go to Mexico City?
For any trip that starts with a flight, the answer is the same: yes. Cancun, Los Cabos, Puerto Vallarta and Mexico City are all reached by air for most Americans, so a passport book is required.
If you are heading to Cozumel or Ensenada on a cruise, the answer depends on the cruise. A closed-loop sailing accepts a birth certificate.
Any cruise that starts or ends outside the US needs a passport.
For a day in a border town, a passport card is enough to show at the crossing. For a longer drive, carry the book.
Even when a birth certificate is technically allowed, a passport book is the safer choice. If something goes wrong on a cruise or a road trip and you need to fly home from Mexico, you cannot board a plane without one.
Passport rules for US citizens flying to Mexico
If you fly to Mexico, bring a passport book that is valid on the day you arrive and that has room for an entry stamp.
The US Department of State says air travelers need one blank passport page for each stamp.
Your passport card stays at home for this trip. It works at land and sea crossings, but it cannot be used to board a flight to Mexico.
Mexico's National Migration Institute, the INM, makes the same point: the card passport can only be used at land border crossings and for visiting the border zone, not for international air travel.
Booking flights to the beach? You can compare flights to Cancun once your passport is sorted, and see our guide to Mexico's airports to choose where to land.
US citizens and the Mexico visa: no visa for stays up to 180 days
Do I need a visa for Mexico? If you are a US citizen traveling as a tourist, no.
Americans can visit Mexico without a visa for tourism. The US Department of State notes that a visa is required for visits of more than 180 days, so stays beyond that limit, or trips to work or study, follow a different process through a Mexican consulate.
The 180 days is a ceiling, not a guarantee. When you arrive, the Mexican immigration officer decides how many days you get, and that number is recorded on your entry permit.
If you plan a long stay, ask for the days you need at the desk and carry proof of your plans, such as a return ticket or hotel booking.
Who needs a visa for a tourist trip to Mexico
| Traveler | Mexican visa needed? | What to show |
|---|---|---|
| US citizen, stay of 180 days or less | No | Valid passport |
| US citizen, stay longer than 180 days | Yes | Apply at a Mexican consulate before travel |
| US permanent resident (green card) | No | Passport plus valid, unexpired green card |
| Holder of a valid US visa | No | Passport plus valid US visa |
| EAD, I-797A, advance parole, I-20 or DS-2019 only | These do not count | Check visa rules for your nationality |

Mexico visa exemptions for US citizens and residents
Searches for a Mexico visa for US citizens, a Mexico tourist visa or Mexico visa requirements all lead to the same answer for Americans: no tourist visa is needed.
There is no Mexico tourist visa application for US citizens, and no fee to pay for one.
If a website offers to sell you a Mexican tourist visa as a US citizen, close it.
What you do get is an entry permit, the FMM, which records your entry and your allowed stay.
That is not a visa, and it is covered in the FMM section below.
The exemption is for tourism and similar short visits. If you plan to work for a Mexican employer, study or live in Mexico for more than 180 days, you need a visa from a Mexican consulate before you travel.
Travelers from other countries should check Mexico's rules for their own passport. Mexico also exempts many foreign nationals who hold a valid US visa or US permanent residence, which is the next point.
Green card holders and US visa holders
Do green card holders need a visa for Mexico? Not for tourism, as long as the card is valid and unexpired.
According to the Consulate General of Mexico in Washington, US permanent residents and foreign nationals with a valid US visa can enter Mexico as visitors without a Mexican visa.
You show your passport together with the green card or US visa at the immigration desk.
Some US documents do not qualify. The consulate lists the employment authorization document, or EAD, the I-797A approval notice, advance parole, the I-20 and the DS-2019 as documents that are not accepted for this exemption.
If those are the only US papers you have, check whether your nationality needs a Mexican visa and apply before you book.
Bring the physical card or visa with you. Airlines check documents before you board, and an expired card can mean being turned away at the gate.
Mexico entry requirements at a glance
Mexico entry requirements are short for US citizens, but each item matters. Here is what a US traveler needs at the border in practice.
You need a valid travel document for your route, an entry permit for most trips, and nothing on you that Mexico bans at customs.
If you drive your own car past the border zone, you also need a vehicle permit and Mexican insurance.
Children need their own documents. The US Department of State advises parents to carry a copy of each child's birth certificate or other proof of their legal relationship to the child.
Mexican minors, including dual US-Mexican citizens, traveling without one of their parents or guardians need notarized written permission from a parent or guardian, or proof of sole custody.
Documents to travel from the United States to Mexico
What do I need to travel to Mexico? For most trips, the documents needed to travel to Mexico by air come down to two items: your passport book and your boarding pass.
Immigration issues the entry permit at the airport.
By land, bring a passport book or card and get an FMM online or at the immigration office at the crossing, unless you stay inside the border zone for six days or less.
Pack a printed or saved copy of your hotel booking and return ticket. Immigration officers decide how long you can stay, and showing your plans makes that conversation easier.
Our guide to whether Mexico is safe to visit covers the US travel advisory by state, which is worth reading before you choose a route.
Mexico entry requirements for US citizens: the checklist
Use this list before you leave home. The entry requirements for Mexico are the same whether you fly to Cancun or drive to Monterrey, with a few extras for drivers.
Mexico entry checklist for US citizens
- Passport book for any flight; passport book or card by sea; by land, Mexico's INM limits the card to the border zone
- Valid for your whole stay, with a blank page for the entry stamp if you fly
- FMM entry permit: digital at airports, online or at the border by land
- Proof of plans: return ticket and hotel booking
- Children: a copy of each child's birth certificate
- Drivers past the border zone: vehicle import permit and Mexican auto insurance
- Quintana Roo stays: Visitax tourist tax paid before you leave the state
If you are flying via Mexico City and need a night near the terminal, a hotel such as the Krystal Urban Aeropuerto keeps you close to your next flight.
Extra documents immigration officers may ask for
Immigration may also ask what you carry, and customs rules catch more travelers than passport rules do.
You must declare cash or its equivalent above 10,000 USD when you enter or leave Mexico.
Electronic cigarettes and vaping devices are illegal to bring in, and carrying them can lead to entry delays and criminal charges.
Goods beyond your personal allowance must be declared: above 300 USD when you arrive by land, and above 500 USD by air.
Bringing weapons or ammunition without a Mexican permit is a serious crime.
Customs items to declare or leave at home
- Cash or equivalents above 10,000 USD: declare on entry and exit
- Goods above 300 USD by land or 500 USD by air: declare
- Vapes and e-cigarettes: not allowed into Mexico
- Medical marijuana: illegal in Mexico, even with a US prescription
- Firearms and ammunition: only with a Mexican government permit
The FMM tourist card (Forma Migratoria Multiple)
The FMM is Mexico's entry permit for visitors, often called the Mexico tourist card. When people look up the FMM form Mexico requires, this is the permit they mean.
It records when you arrived and how long you may stay.
The FMM is valid for a maximum of 180 calendar days and for one entry. The immigration officer decides how long you can stay, and the days granted can be fewer than 180, so check what is written on your stamp or record before you plan a long trip.
How long can US citizens stay in Mexico? Up to 180 days on one FMM, if the officer grants it.
Leaving Mexico ends that permit, and you get a new one on your next entry.
Today there are two ways to get one. Air travelers receive a digital FMM at the airport. Land travelers apply online or at an immigration office at the border.
FMM essentials
- What it is: Mexico's visitor entry permit, also called the tourist card or visitor permit
- Maximum stay: 180 calendar days, single entry
- Who sets your days: the immigration officer on arrival
- By air: issued digitally (FMMD) at all international airports
- By land: apply online or at an INM office
- Border zone exception: within 12 miles (20 km) of the US border for 6 days or less, no FMM needed
If you fly, there is no printable FMM form in English to fill out in advance. The permit is issued digitally when you arrive at the airport.
Forma Migratoria Multiple (FMM): digital at airports
FMM stands for Forma Migratoria Múltiple, the multiple migration form. At airports it is now digital, called the FMMD.
Mexico issues the FMMD at all its international airports. You do not fill out a card on the plane. The officer stamps your passport with the entry date, or you may be directed through a self-service E-Gate that prints a receipt with a QR code.
Keep that receipt or a photo of your stamp until you leave. Air travelers can download a record of their FMMD from the INM website, which is useful if anyone asks how many days you were granted.
The Mexico immigration form by land and online
The Mexican FMM form for land travel works differently. All travelers entering by land must apply for an FMM online or at an INM office at the crossing, according to the US Department of State.
There is one exception. If you are staying within 12 miles (20 km) of the US border for six days or less, you do not need an FMM.
A day trip to Tijuana or a weekend in a border town usually falls under that rule.
If you are driving deeper into Mexico, to San Felipe or Mazatlán for example, stop at the immigration office at the border and get your FMM before you continue.
Mexico passport requirements: validity, blank pages and condition
Mexico passport requirements are simpler than many travelers think. There is no six-month rule. Mexico asks for a passport that is valid when you enter, and the Consulate General of Mexico says it must be valid for the length of your stay.
Air travelers also need one blank passport page for each stamp. Some airlines or insurers repeat the six-month rule from other countries, but it is not Mexico's requirement.
If your passport expires during your planned stay, renew it first.
Mexico tourist tax: Visitax and state fees
Mexico tourist tax questions usually mean the Visitax. It is a state tax charged by Quintana Roo, the state that includes Cancun, Playa del Carmen, Tulum, Cozumel and Isla Mujeres.
The Visitax is mandatory for all foreign tourists visiting Quintana Roo, under Article 51 octies of the state's tax law. It applies to adults and children alike.
Pay it on the official site, visitax.gob.mx, or through companies authorized by the state tax service.
Fees and rules can change, so check the official state source before you travel.
If you are staying in Cancun's hotel zone, the Krystal Grand Cancún all-inclusive is one option on the beach, and the Visitax applies to every foreign guest whichever hotel you choose. Our guide to cash, cards and pesos in Mexico explains how to pay once you land.
Passport book or passport card: land, sea and cruise entry
Can you go to Mexico without a passport? Yes, but only by land or sea, and only with the right substitute.
Do you need a passport to go to Tijuana, Mexico? By land, US authorities accept a passport book or a passport card, and Mexico's INM accepts the card for land crossings and visits to the border zone. Coming home, some trusted traveler cards such as SENTRI and Global Entry can also be used to re-enter the US by land.
Do you need a passport to go to Mexico on a cruise? By sea, a passport book, passport card, NEXUS, SENTRI or FAST card, or a state-issued REAL ID is accepted. On a closed-loop cruise from a US port, a birth certificate with a raised seal works, plus a government photo ID if you are 16 or older.
Driving your own car brings two more requirements. A US-registered car going beyond the border zone needs a Temporary Vehicle Import Permit, the TVIP, from Banjercito, which you can request online 10 to 60 days before travel.
The permit fee runs about 45 to 59 USD, plus a refundable deposit of 200 to 400 USD.
The Baja California Peninsula, the Sonora Free Zone, Quintana Roo and the border zone do not require a TVIP.
You also need Mexican auto insurance in every case, because a US policy is not sufficient.
Driving into Mexico: what you need
- Passport book for every person in the car; Mexico's INM accepts a card only for the border zone
- FMM for each traveler beyond the border zone or staying over 6 days
- TVIP from Banjercito, unless you stay in Baja, the Sonora Free Zone, Quintana Roo or the border zone
- Mexican auto insurance: a US policy is not enough
Flying in and renting a car instead? You can search car rentals in Mexico and skip the vehicle permit, then read our guide to getting around Mexico before you set off.
Final Thoughts
For most Americans, getting into Mexico takes less paperwork than they expect. Fly with a passport book, cross by land with a book, or a card if you stay in the border zone, and use a birth certificate only on a closed-loop cruise.
You do not need a visa for a tourist stay of up to 180 days, and Mexico has no six-month passport rule. The FMM is now digital at airports, but the officer still decides how many days you get, so check your stamp or receipt.
Heading to Cancun or Tulum? Pay the Visitax on the official site. Driving? Sort out insurance and, past the free zones, a vehicle permit. Then pick your season with our guide to the best time to visit Mexico.
FAQ: Mexico Entry Requirements
Do you need a passport for Tijuana and other border towns?
You need proof of citizenship. A passport book works, and so does a passport card, which Mexico's INM accepts for land crossings and the border zone. If you stay within 12 miles (20 km) of the border for six days or less, you do not need an FMM.
Do minors need a passport to go to Mexico?
Children follow the same document rules as adults, so a child flying to Mexico needs a passport book. Parents should also carry a copy of each child's birth certificate. Mexican minors, including dual citizens, traveling without a parent need notarized permission or proof of sole custody.
Do you need a passport for a Mexico cruise?
On a closed-loop cruise that starts and ends at the same US port, a birth certificate with a raised seal is accepted, plus a photo ID if you are 16 or older. Other sea travel accepts a passport book, passport card, trusted traveler card or REAL ID.
How long can US citizens stay in Mexico?
Up to 180 days on one FMM. The immigration officer decides the exact number of days when you arrive, so it can be fewer. Longer stays need a visa from a Mexican consulate.
What happens if you don't pay the Visitax?
The Visitax is mandatory for all foreign tourists in Quintana Roo under state law, so you are expected to pay it before leaving the state. Pay on the official visitax.gob.mx site to avoid any problem on departure.
Can you use a passport card to go to Mexico?
Yes for sea travel, and by land for visits to the border zone; Mexico's INM says the card is not for travel deeper into the country. A passport card cannot be used to board a flight to Mexico.
Do US citizens need an FMM to enter Mexico?
Most do. Air travelers receive a digital FMM at the airport automatically. Land travelers need one unless they stay within 12 miles (20 km) of the border for six days or less.
Is the FMM no longer required for entry into Mexico?
It is still required, but at airports it is now digital, so you no longer fill out a paper card. Land travelers still apply online or at an INM office, unless they stay within 12 miles (20 km) of the border for six days or less.
Can you use a REAL ID instead of a passport to go to Mexico?
Only for sea travel, where the US Department of State lists a state-issued REAL ID as accepted. A REAL ID cannot replace a passport book on a flight to Mexico.
