On May 29th, 2026, just in time for the World Cup, the U.S. State Department published its updated travel advisory for Mexico.

I have found these advisories useful and they are updated from time to time.
You can see the advisory for yourself here.
The advisory summary begins thusly: “For Americans traveling to Mexico for FIFA World Cup 2026 matches, follow the latest guidance from the U.S. Embassy in Mexico.” When you click that hyper-link you go to a page called U.S. Embassy and Consulates in Mexico FIFA World Cup 2026™ . It says that “The Mexican government expects more than 5.5 million visitors” during World Cup time. That’s a lot!
At the bottom of that page it says U.S. Embassy & Consulates in Mexico and if you click that you go to a page which actually has links to information pages about the U.S. embassy in Mexico City and the 9 U.S. consulates on Mexican soil.
Now, back to the Mexico advisory page here. It has general information and also breaks Mexico down into four categories:
Level: 4 – Do not travel (six states)
Level: 3 – Reconsider travel (six states)
Level: 2 – Exercise increased caution (16 states and Mexico City)
Level: 1 – Exercise normal precautions (2 states)
There’s also a color-coded map that accompanies it.
If you are planning to travel in Mexico, or even considering it, I recommend you look over the State Department’s material.
