Well as I'm an American of half-Norwegian descent currently living in Minnesota, Norway would be one of my first choices. I know it's horrendously expensive to live there, but it's a beautiful country and the people there have a strong reputation for friendliness (especially towards us Minnesotans!). I also speak a little of the language (took it in high school), though I'm by no means fluent.

My other main choice would probably be Britain. I've always been fascinated by the land and its history, and would love to live in the middle of all that. It's also a relatively short distance from Ireland, which is a plus as I'd want to visit there every now and then. The UK also seems to be a bit of a....quirky place, which appeals to me as well.
