I couldn't do it forever, but I do live vicariously through House Hunters International, especially when their employer gives them a monthly housing allowance of $10,000 or so.
I definitely couldnt do Africa, Asia, or Easter Europe.
I did almost two years in the culture most similar to our own. I absolutely loved it -- but by the end I was incredibly homesick.
I'm not sure how much of that was a function of missing friends, gf, family, and wake forest, and how much was missing that fundamental American-ness. Not sure that I could do it for forever.
Short of places like North Korea, Cuba, or Vietnam, I don't know of any country that requires you to renounce citizenship.
I am currently in Africa and loving it. Although it definitely helps to be in a large city.
I think the hardest thing is not being around/able to see family and friends
Other than that, it really isnt that difficult
Right, just a hypothetical.
I doubt anyone would do it, save the most Lee Harvey types amongst us. I believe I've read that you cannot renounce your American citizenship solely for the reason of avoiding taxes. Some have tried this though it seems to work best if your name is GE, Exxon, or Dart.
As some who lives abroad with no plans to return home any time soon ...
I'm not sure I could live ANYWHERE permanently. Not close to home, not far from home. I'm just a wanderer at heart, and with the internet / skype / etc ... the parts of American culture (I watched every game of the NCAA Tournament, every NFL game I wanted too, etc - all in HD ... I talk to my family regularly via video chat, etc) that I really want to have I don't have to miss. This isn't 1860 anymore.
