I should have an in depth article on Mexico up in the next couple days. If you are planning to move there and work as a foreigner, you cannot do it legally until your are a permanent resident, which can take 4-5 years. This is why we left. I often don't care what is legal or not, but instant deportation is the punishment, which could probably be avoided with a hefty and recurring bribe, after all it's Mexico :) That area is beautiful, and we made some amazing life long friends there, but Mexico isn't as easy as it was 5 years ago, the laws have changed and they are cracking down.
