The Participant Information Form is required. In order to enter Mexico as a US Citizen you need to have one tourist migratory form (FM-T) per person. (Cost of FM-T is included in airfare). These forms are obtained at the first port of entry, at the borders, or at Mexican consulates and embassies. Keep the FM-T in your possession at all times and return to authorities before leaving Mexico. A Visa is not required but a passport is needed to obtain a FM-T permit and may be required to re-enter the US.
Procedures for obtaining the FM-T vary with the nationality of each visitor. Request the requirements for your nationality in any of the Mexican Consulates or Embassies in your respective countries.
The Intelligence Reform and Terrorism Prevention Act of 2004 requires that by January 8, 2007, travelers to and from the Caribbean, Bermuda, Panama, Mexico and Canada have a passport or other secure, accepted document (Merchant Mariner Document or Air NEXUS card) to enter or re-enter the United States
