It is not clear to me what the benefits are of holding an FM 2 over an FM3. La H. your post still seems to read that after the 5 year period with an FM2 and and the changed status that you can hold land with a title.
Is it not the case that the FMT has never been required in the free zone?
The FMT has always been required even in the Free Zone
if you stay longer than 72 hours. It's been pretty much ignored by everyone, though, including immigration.
The FM2: IF you decide early on that you want full time permanent status in Mexico as an immigrant, then going with an FM2 is the way to go because you'll get to your objective faster. Hold your FM2 for the required number of years and you can then apply for the next level-- the
permanent permanent deal, just one step down from citizenship. You get a blue-colored card if you make it through that step. And once you've got the blue card (
not the FM2) you can own land just like a Mexican, without restriction. At least (disclaimer here) that's what I've been told by folks who are immigration pros...
You can't apply for that status of immigration if you're holding an FM3, and the number of years you've had that FM3 don't count towards the years you need with an FM2.
If you don't care about being that permanent and/or don't intend to become a Mexican citizen, then an FMM or FM3 is all you need.
