Two years ago, INM told us we could change to residente permanente next year, then they changed the rules.
Recently, they told us that we could have our previous FM3/FM2/Inmigrante counted and become residente permanente at our next renewal date; next week.
Today, it appears that may have changed too!!!!!!
I will be that there are folks, who took cars out of Mexico, who are really fuming about now.
As I have posted before: How do we plan ahead?
The best plan in Mexico is to sit tight for awhile even when you think you know what's being talked about.
