I haven't seen any citizenship restrictions, though usually there is a "you must live here at least X years or repay the benefits" restriction.

Edit: If you mean culturally, I really can't imagine any problems as long as you're friendly, respectful, and speak the language. I've lived in some fairly remote places and never had an issue; a lot of people in my experience are pretty hands-off -- even if they don't like you, they don't bother you unless you bother them.
