A tourist visa is a “Forma Migratoria Multiple” (FMM) and one is not required for those under the age of two. It is required for everyone else, even in the “Free Zones”, unless you are a legal resident. It allows one to enter Mexico, one time, for up to 180 days but recently, often for shorter periods. The back of the form confirms it is for one entry; however, in Baja California it may be used for multiple entries. The cost is 638 pesos.
Please note, the FMM cards are being eliminated. When a person enters Mexico, you will not be issued a FMM. You will have a stamp in your passport and in that stamp will be written the number of days you may be in Mexico. Similarly, when a person has a pre-approved visa from a Mexican consulate, in their passport, a FMM will not be issued and a date will be stamped on the pre-approved visa. As well, it will be written CANJE 30 days. When a TR or PR resident leaves Mexico your passport is stamped with date and written is your visa status and SALIDA. And, when entering Mexico, stamped with date, visa status and the word ENTRADA.

There is an electronic FMME. It is available here. Complete the application form. Print the FMM and keep it with you to be validated where you enter Mexico.
The immigration authorities must stamp it. Once the form has been printed, you have 30 days to enter Mexico and you may remain in Mexico (without engaging in paid activities).
The traditional way of obtaining the FMM at ports of entry is still in force. The electronic version allows you to fill out the form in advance. It is very important to keep the stamped portion of the FMM that corresponds to the record of entry, as this is proof of your legal entry into Mexico and will be required when you leave the country.
Prior to your FMM expiration normally you must return to the border as it can not be extended in Mexico. The FMM fee is currently 638 pesos per person. If your FMM does expire while in Mexico, and you are flying out, please go to Inmigracion at the airport and pay for another prior to boarding your plane. If driving you are to do the same.
In Mexico, as a tourist, you must carry both your passport and original FMM tourist card.
