Recommended
If you have a flight to the United States, authorities and airlines recommend arriving at the airport at least three hours before the scheduled departure. This extra time allows you to complete the check-in process, pass through security checkpoints, and address any additional screenings without delays. Arriving early is especially important for international travel, where controls are often stricter than on domestic flights.
In addition to presenting your boarding pass, you must comply with the requirements established by the airline, the Transportation Security Administration (TSA), and Customs and Border Protection (CBP). Therefore, planning your arrival with sufficient time can help you avoid delays or even missing your flight.
Essential documents for traveling to the United States
Before heading to the airport, verify that you have a valid Mexican passport and a US visa that is valid for the dates of your trip. Once you have both documents in order, you can purchase your flight tickets and prepare your itinerary.
It is recommended to check the departure terminal in advance and the specific requirements of the airline, as some companies have exclusive areas for international flights.
What to do upon arriving at the airport?
Upon arrival at the airport, you must check in, if you have not done so online, and document your luggage if you have bags to register.
During this process, airline personnel may ask some questions related to your trip, such as:
- ¿Cuál es tu destino?
- ¿Cuántos días permanecerás en Estados Unidos?
- ¿Cuál es el motivo de tu viaje?
Additionally, you must complete the Statistical Form for Mexicans for international flights.
Prohibited items in carry-on luggage
After checking your luggage, you must go through the security checkpoint. There are important restrictions you should consider to avoid issues during inspection.
It is not allowed to transport the following in carry-on luggage:
- Líquidos en envases mayores a 100 mililitros.
- Armas de fuego.
- Objetos punzocortantes.
- Herramientas como taladros, sierras o pistolas de clavos.
- Bates de béisbol o sóftbol.
- Bastones, porras o cachiporras que puedan utilizarse para causar lesiones.
These items must travel in checked luggage, when permitted by regulations, or be left out of your luggage entirely.
Food and money: what you must declare upon arriving in the United States
Once you land in the United States, CBP officers may inspect certain products you are carrying.
Fresh fruits and vegetables are subject to inspection to prevent the entry of agricultural pests or diseases. Therefore, it is recommended to keep packaging and purchase receipts to demonstrate their origin.

You should also consider that:
Pork and its derivatives coming from Mexico are generally not admissible.
Milk and eggs may be inspected before their entry is authorized.
If you are carrying more than 10,000 dollars in cash, you must declare it to the authorities.
Questions you may be asked at Immigration
When going through immigration control, the CBP officer will look to confirm that your visit is temporary and meets the conditions of your visa.
Among the most common questions are:
Where are you going?
What is the purpose of your visit?
What do you do for a living?
Where do you live?
Where are you coming from?
What are you bringing from Mexico?
To facilitate the process, it is advisable to bring a printed copy of your return flight reservation or any evidence showing that you plan to return to your country of residence.
If you are traveling without a return ticket, you must explain when and how you plan to return. The important thing is that the duration of your trip is consistent with the activities you will be performing.
How long can you stay in the United States?
If your entry is approved, the CBP officer will determine the authorized period of stay. In many cases, travelers with a tourist visa receive permission to stay for up to six months, although the exact duration depends on the evaluation performed at the port of entry.
Therefore, you must always respect the deadline for your stay indicated by immigration authorities.
Returning to Mexico
When it is time to return, you will go through a TSA security checkpoint again at the US airport.
The rules are similar to those applied during your departure from Mexico: liquids cannot exceed 100 milliliters per container in carry-on luggage, and it remains prohibited to transport objects that could be used as weapons.
Arriving with enough time, carrying your valid documents, and knowing the security rules can make your trip to the United States much simpler and free of setbacks.
