I think someone should suggest to the Mexican President that we will require the same procedures/documents that Mexico requires of Americans in Mexico. In fact, I think we should tell him (the President of Mexico) we are going to arm our border patrols with exactly the same firepower their border guards have at their southern border.....

I think we should get as many as possible to publish these facts. Every time someone suggests it’s profiling, we need to just say it’s standard procedure and quote from the US Embassy website.

We don't have to suggest a damned thing; Just do it!

Tom Clancy described the process many years ago : it's called Temporal Reciprocity. Just announce that starting on a certain date the requirements to enter the United States for any reason whatsoever will mirror exactly the Mexican requirements for Americans entering Mexico. If Mexico changes the requirements, the U.S. track the new rules without any additional action necessary on our part.

Same for residence and property ownership.
Mexico, then, would be totally responsible for how their citizens are treated in the US. They would literally create the rules and laws, and corresponding penalties for their violations..
