My grandson is a dual citizen - he is a British Citizen and an American Citizen. He was born in England with a British mother and an American father. It was up to them to determine what they wanted to do about citizenship. He was made a British citizen by the mother and my son went to the American Embassy the day he was born and registered him as an American Citizen. He is not a naturalized American Citizen, he is a natural born American Citizen. He was issued an American Passport that day. When he arrives in this country, he gets in the American custom line. If his mother comes to this country, she gets in the foreign custom line.
Because he has dual citizenship, if he ran for public office in Britain, depending on the office, he would likely have to give up his American Citizenship so he would have allegiance to only one country, Britain. The same would be true if he ran for public office here, based on the requirement for that office.
His desire is to go to college in this country and he can do that easily because he is an American Citizen.
He is a teen ager and right now, he would like to live in an American Academy store as Britain doesn't have a huge store like Academy devoted to sports. He wears Houston Astros, Houston Rockets, and Dallas Cowboy shirts and jackets to his private school in England. He was in Miami for a tennis school this past month.
The Supreme Court made a distinction between natural-born citizens and natural-born subjects in 1830. You can only be one (by Treaty) and not both. The point is that citizenship status naturally follows the status of the father and the allegiance of the parents. In order to be a natural-born citizen and thus be eligible for the office of president, the father would have to be a U.S. citizen and the parents would have to have allegiance to the United States. If the mother maintains allegiance to Great Britain, and the child holds dual citizenship, then he simply is not a natural-born citizen of the U.S., the reason because it would require the operation of some other form of law to determine citizenship status. No such determinations are necessary for a person who fits the Supreme Court’s definition of natural-born citizen.
