Given that the Mexican government actively assists with the ongoing violation of American sovereignty that is illegal immigration, who the hell do they think they are imposing this requirement?

Starting March 1, Mexico will require U.S. citizens traveling south of the border to have valid passports.

The new rule applies also to U.S. legal residents, who will have to show their green cards or other documents demonstrating their legal status in the U.S.

In other words, all us gringos had better follow Mexico's border rules or we will be turned away -- or maybe end up in one of Mexico's jails under the watchful eye of its narco-terrorist corrupted law enforcement agencies.

Which leads me to ask why they are not setting up water stations and providing "sneak across the border" websites for undocumented American tourists to come south while evading Mexican law -- especially because they will be spending so much of that gringo dinero that keeps the Mexican economy afloat.
