"Natural Bron"

I think it is fine. If  someone's parents are  citizen of America, he/she will be the citizen of USA even if he/she were bron abroad. Because his parents are American, he will recieve the American education. He will learn about his country. He can be the president. In the other words, to be bron abroad doesn't mean to be foreigner and doesn't mean you must learn other different culture. Acturally,this concept is really equivocal. It's hard to say whether it's coorect or not. But I believe this qualification must be useful.
