Yes.

To be clear, the date stamped in one's passport is the future date which one must leave by.

This system will also lessen the frequent overstayers that "lost" the bottom part of the paperwork they were to keep that showed X days they were allowed to stay in México. Granted, a piece of paper is easy to lose but....it happens quite a bit, people abusing the system. Passports are generally not so easily lost.

Another speculated intent is to cut down on those living in México yet never going thru the Residency process : making a "border run" after their X days up (or they have mysterously lost their paperwork) then re-entering 24 hours or so later in hopes of another 180 days, then repeat repeat. Some people have been doing this for years.

As a Permanent Resident my dance was opposite...I had the bottom part of the form to keep (stamped @ the INM window near check-in gates upon departure) with RP, Residente Permanente, while I was OUT of México then turn in upon re-entry back into México. So, easier for us too.

It's all good.
