RG: That would be great to see it. Maybe put something on tripadvisor.com so people will be prepared. I wonder what it means. There is already a form called FMM(Forma Migratoria Mexicana). It is the form Mexicans fill out when they leave the country and have to present to INM when they return. Do you know what the new "FMM" means?
Jim - You missed it above...FMM is Forma Migratoria Multiple. It's a multi-purpose form, for Mexicans and Tourists and Diplomats and Flight Crew, etc.
