It is a truism in there. I was meeting with an executive who had moved form UK with his family to here. I asked him how his kids were settling. He said at first they were working hard to get rid of their accent but then realized it is considered "cool" in US and they went the other way around and are so happy!
No Thomas, it doesn't mean you can move here. They have your picture at border crossing for violating many articles of forum posting and won't let you in.
