The tourist card is issued upon presentation of proof of citizenship, such as a U.S. passport or a U.S. birth certificate, plus a photo I.D., such as a drivers license. Tourist cards are issued for up to 90 days with a single entry, or if you present proof of sufficient funds, for 180 days with multiple entries. Upon entering Mexico, retain and safeguard the pink copy of your tourist card so you may surrender it to Mexican immigration when you depart. You must leave Mexico before your tourist card expires or you are subject to a fine. If you wish to stay longer than 180 days, or if you wish to do business or conduct religions work in Mexico, contact the Mexican Embassy or the nearest Mexican consulate to obtain a visa or permit.
Persons conducting religious work on a tourist card are subject to arrest and deportation.
If you plan to live or retire in Mexico, consult a Mexican consulate on the type of long term visa you will need. As soon as possible after you arrive in the place you will live, it is a good idea to register with the U.S. Embassy or the nearest U.S. consulate or consular agent. Bring your passport or other identification with you. Registration makes it easier to contact you in an emergency. Minors A child under the age of 18 traveling with only one parent must have written, notarized consent from the other parent to travel, or must carry, if applicable, a decree of sole custody for the accompanying parent or a death certificate for the other parent.
