After making the following post
I had a lot of people laughing.
The people at INM promised they would call within 2 - 3 weeks, or as soon as the cards arrived. Well so far no call, but today, about noon, Tom went up to ask what's happening?
Well surprise, surprise, the cards are in! So he got his name on the list and texted me. I then dressed and drove up. 45minutes to an hour after I arrived we were in, signatures made, and cards handed over.
We are now Permanent Residents of Mexico.
We never need to go through this again!
