Dang is a term used by Southern Baptists who are trying not to cuss. I'm not sure what the required residency time is in order to become a naturalized citizen. Some would say the first generation is considered a yankee ("dang yankee" since they didn't just come for a visit and go home). Others would say 44 years is plenty of time to claim to be a Southerner. I go with the theory it's all about attitude and where your loyalty lies. For example, when we moved to Chicago, on the first day of school my daughter came home upset. The teacher had gone around the room asking kids where their family was from. The responses were, "We're Polish Americans", or "German Americans", etc. My daughter wanted to know what we were. My answer was "We're Americans ... And if your teacher requires a qualifier, because she wants everybody to identify with some other country and not give their full loyalty to these here United States, tell her we're Confederate Americans."
