Mexican passport holders can board US-bound flights from a Mexican airport
When travelling to the United States from Mexico, it's important to be aware of the documentation requirements. For Mexican citizens with a valid Mexican passport but no U.S. visa, there may be concerns about their ability to travel safely on a domestic flight within the U.S. While a Mexican passport can serve as proper identification, the Transportation Security Administration (TSA) can act as immigration enforcement. The TSA may inquire about an individual's lawful status, and if they cannot discern legal presence, they can refer the traveller to the nearest Customs and Border Protection (CBP) office.
To avoid potential issues, it is recommended to review the TSA's guidelines before travelling. Additionally, individuals should be aware that the United States Border Patrol operates traffic checkpoints near the Mexico-United States border, and they have the authority to conduct checkpoints within 100 miles of the border. Border Patrol agents have the discretion to selectively refer motorists to a secondary inspection area for additional questioning.
Furthermore, when entering the United States by land or sea, Mexican citizens must obtain an entry permit, even for travel within the immediate border area. This can be done by visiting a National Institute of Migration (INM) office or their website. Mexican immigration authorities may ask to present both the passport and entry permit at any point during the stay in Mexico and may detain travellers who cannot provide proper documentation.
In summary, while Mexican passport holders can board US-bound flights from a Mexican airport, it is crucial to ensure that all necessary documentation is in order, including a valid passport, visas (if required), and entry permits when entering Mexico by land or sea. Travellers should also be prepared for potential questioning by border authorities and refer to official sources for the most up-to-date guidelines.

US passport cards may not be accepted for entry into Mexico
If you are a US citizen and plan to travel to Mexico, you need to carry a valid passport book. US passport cards are not accepted when entering Mexico by air. This means that if you attempt to enter Mexico at an airport with only a US passport card, you may be denied admission.
US passport cards are wallet-sized, plastic passports that have no visa pages. They are valid for US citizens who travel by land and sea from Canada, Mexico, Bermuda, and some Caribbean countries. The passport card is also cheaper than the passport book. However, it is not valid for international travel by air.
If you are entering Mexico by land, you must have a valid passport book or card. You must also obtain an entry permit (Forma Migratoria Multiple or FMM) by stopping at an INM office or applying online. This is required even if you are only travelling within the immediate border area (up to 20 km into Mexico). The FMM must be stamped at an INM office upon entry and exit.
It is important to note that Mexican immigration authorities determine the authorised length of stay for travellers and either place a date stamp in the passport or direct travellers through an electronic gate that generates a printed receipt with a QR code. Therefore, it is crucial to carry a valid passport book when travelling to Mexico by air to avoid any issues upon arrival.

Mexican passport holders can travel visa-free to over 90 countries

For those entering Mexico by land, a valid passport book or card is necessary. Travellers must also obtain an entry permit (Forma Migratoria Multiple or FMM) from an INM office or online, even if not explicitly instructed to do so by Mexican officials. This includes those within the immediate border area, extending approximately 12-20 km into Mexico.
Regarding Mexican passport holders, they enjoy visa-free access to a significant number of countries worldwide. As of 2025, citizens of Mexico can enter 158 countries and territories without a visa or with a visa on arrival, according to the Henley Passport Index. This includes popular destinations such as Singapore, the United Kingdom, the United Arab Emirates, and the entire European Union. The Mexican passport is highly desirable and ranked 22nd globally due to its high mobility score.
However, it's important to note that there are still countries that require a visa for Mexican passport holders, such as Taiwan, the United States, and Australia. Additionally, certain countries, such as Kuwait, Lebanon, Libya, and Yemen, have specific restrictions for travellers with evidence of previous travel to Israel, such as passport stamps or visas.
In terms of identification for domestic flights within the US, a valid and unexpired foreign passport is generally accepted as identification. However, it is always recommended to review the TSA's most up-to-date guidelines before travelling, as there have been instances of erroneous denials by TSA agents.

US Border Patrol operates traffic checkpoints near the Mexico-US border
To enter Mexico by air, a valid passport book is required. Those attempting to enter Mexico at an airport with a U.S. passport card only may be denied admission. For travellers entering Mexico by air, the Mexican immigration authorities use a Forma Migratoria Multiple Digital or FMMD. Upon arrival at a Mexican airport, the immigration authorities determine the traveller's authorised length of stay and either place a date stamp in the passport or direct the traveller through a self-service electronic gate (E-Gate) that generates a printed receipt with a QR code.
To enter Mexico by land, a valid passport book or card is required. For those entering Mexico by land, it is mandatory to stop at an INM office or go online to obtain an entry permit (Forma Migratoria Multiple or FMM). This includes travellers within the immediate border area (approximately 12 to 20 km into Mexico). The FMM must be stamped at an INM office upon entry to and exit from Mexico.
The United States Border Patrol operates 71 traffic checkpoints, including 33 permanent traffic checkpoints, near the Mexico–United States border. These checkpoints are located between 25 and 75 miles (40 and 121 km) of the Mexico–United States border along major U.S. highways; near the southern border of the contiguous United States. Their location at interior sites allows them to deter illegal activities that may have evaded official border crossings along the frontier. The checkpoints are divided among nine Border Patrol sectors.
The stated primary purpose of these inspection stations is to deter illegal immigration and smuggling activities. After the September 11 attacks in 2001, they took on the additional role of terrorism deterrence. At these checkpoints, every motorist is stopped and asked about their immigration status. Border Patrol agents at checkpoints have legal authority that agents do not have when patrolling areas away from the border. The United States Supreme Court ruled that Border Patrol agents may stop a vehicle at fixed checkpoints for brief questioning of its occupants even if there is no reason to believe that the particular vehicle contains people unlawfully present in the country.
In fiscal year 2008, thirty-nine tactical checkpoints were in operation. Tactical checkpoints lack permanent buildings and support permanent checkpoints by monitoring and inspecting traffic on secondary roads that the Border Patrol has determined are likely to be used by individuals in the country illegally or smugglers attempting to evade apprehension at permanent checkpoints. A draft plan for the I-19 checkpoint in 2009 proposed to model it on the largest previous permanent checkpoint, the I-35 checkpoint north of Laredo, Texas, but would surpass it in size (18 acres) and inspection lanes (8 primary, 7 secondary).
In the United States, a domestic flight is a flight made within the country's boundaries. In other words, a domestic flight is within the U.S. without any layover or destination in another country. For example, a flight departing from Miami, Florida, and arriving in Seattle, Washington, is considered domestic. To board a domestic flight, a REAL ID-compliant license will not be required until May 7, 2025. Even without a REAL ID, another form of identification, such as a valid and unexpired foreign passport, can be used. The list of approved identification to fly domestically includes foreign government-issued passports (must be valid) and/or a U.S. Citizenship and Immigration Services Employment Authorization Card (I-766).
There have been reports of individuals who could not fly with these documents due to erroneous TSA agent denials. In such instances, inform the TSA agent that these are acceptable documents according to posted Transportation Security Administration guidelines. It is recommended that travellers review the TSA’s most up-to-date guidelines before their domestic flight.
