U.S. v. WONG KIM ARK, 169 U.S. 649 (1898)
169 U.S. 649
It thus clearly appears that by the law of England for the last three centuries, beginning before the settlement of this country, and continuing to the present day, aliens, while residing in the dominions possessed by the crown of England, were within the allegiance, the obedience, the faith or loyalty, the protection, the power, and the jurisdiction of the English sovereign; and therefore every child born in England of alien parents was a natural-born subject, unless the child of an ambassador or other diplomatic agent of a foreign state, or of an alien enemy in hostile occupation of the place where the child was born.
III. The same rule was in force in all the English colonies upon this continent down to the time of the Declaration of Independence, and in the United States afterwards, and continued to prevail under the constitution as originally established.
You need to read that State Dept. page more carefully. You cannot lose your U.S. citizenship unless you choose to obtain citizenship in another country. So Obama was born with dual citizenship, yes. That does not make him any less of a natural born citizen, though. Certainly a question would be raised if he had dual citizenship today, but he doesn’t, so it’s a non-issue. The accident of birth that gave him dual citizenship does not deprive him of the rights of a natural born citizen.
Is he really a NBC? I don’t know. I don’t think it’s likely the State of Hawaii would knowingly participate in a fraud. Is there a fraud that Hawaii doesn’t know about and is itself a victim of? That’s possible, but as of now, there is no evidence to support that theory.
He’s a socialist/communist enemy of America, of that much I am sure. And IF he was born in Hawaii, he’s a NBC.
