What you probably can't do is go back to the US, you'd have to leave Mexico directly.
Well, the language is not as misleading as you had implied, if you would re-read the questions in the quoted Q&A.
First of all, the whole section
YVR Cockroach quoted in
his post is meant for those international visitors to the States, who also want to extend their stay in the U.S. under VWP.
Secondly, even when, like you say, Mexico allows them to be in Mexico beyond the original 90 days,
their very intention is to re-enter the States with a new 90-day admission. Not only this hypothetical Mexico stay won't help them with a new 90-day clock, but also US considers those visitors over-stay (adding both US days and Mexico days). Upon re-entering the US, they can be locked up (such as what happened to
this poor Aussie girl). Why would anyone want to risk it? You got it right. They would have to leave Mexico directly.
Thirdly, then what's the point for them to go to Mexico to start with, when all they want is stay in the States for another 90 days (or 6 months, like OP's mom)?
As a non-native English speaker, I think I understand the quoted language correctly. I guess I just don't understand how your replies fit with the extending-US-visa scenario.
