Keep your auto insurance coverage going in the states, even if you don't even have a car going there. I just got bent over a barrel for my car insurance because I haven't had coverage in years while I was in CR. Now I have to pay about double for the next year, then I'll qualify for the normal rate again. No one told me that's how the game is played, but I'm telling you. So keep at least minimum coverage going while you live in CR. Depending on how long you're going to be in CR, this could save you some money in the long run.
