My wife and I just got our resident permanente visas today at the Detroit Mexican consulate. Once we enter Mexico we have 30 days to finalize the visa process. I understand that once we have the permanent visa we will no longer be able to keep our 3 year old US car in Mexico . My question is this, can we drive our car to SMA, return to the US in about 25 days, sell the car there and then fly back to SMA before the 30 day period expires? What we are trying to avoid is having our dog flown down in the plane's luggage compartment and also be able to take limited items in the car before our household goods arrive about 3 months later.
