I don't think I'd be willing to lose my American citizenship to move somewhere else. I love this country, in spite of all its' current problems.
My family has a house in Ireland, and I've been many times. But as proud as I am of being of Irish descent, I still cherish my being an American above all else.
I do not consider myself Irish-American, but American-Irish.
If I had to movesomewhere other than this country, I guess I'd chose Calgary, Vancouver, Edmonton, or Banff, Canada, as I prefer cooler climates to more tropical ones. New Zealand looks awful pretty as well, as does Amsterdam, Netherlands. I probably would enjoy Scandinavia, (Finland,Norway, Sweden and Denmark)
My sister lived in Germany for a while and really loved it. She said they are compulsive neat freaks though.
