Foreigners who intend to enter Mexico should consult the legal requirements contained in Article 37 of the Migration Law.
For those nationalities required to have them, visas are authorized and issued at our consulates abroad, not at the points of entry into Mexico.
Please bear in mind that current legislation does not permit entry into Mexico if requirements to travel to a neighboring country have not been met. To avoid surprises, please inform yourself before starting out.
The provisions of the law on migration are observed at all times and Mexican authorities are required to make sure they are enforced.
