Congratulations on your early retirement!
There's lots of information on this board about retiring overseas, I've noticed. My FIL lived abroad in South America for a few years, and when he passed away I wrote this post
about what we've learned from the experience. I hope you have many, many years of a full and happy life abroad, but if you take care of some of these things early on it could save your family here in the US a lot of hassle! (Not trying to discourage you -- just sharing information that would have made things easier for us).
Welcome to the boards and let us know how it goes.
