It would take a constitutional amendment to outlaw dual citizenship, and frankly, it is one that is definitely needed.
Just like those people who were crazy because they believed the Earth circled about the Sun rather than vice-versa.
Thanks for that information. I wondered when dual citizenship became fashionable. I was always taught that when one became an American Citizen prior citizenship to another country was to be renounced. As far as I am concerned it should be. I thought too if we took out citizenship in another country we would lose our American citizenship. Who knew..and 0bama is counting on the majority of the American population to be completely stupid about this..so far he is getting away with this crime. The Supremes need to get on this now.
Additionally, dual citizenship should NOT disqualify a person for any position within the US Government. Why? How can a person control the grant of citizenship from another nation? What if Hugo Chavez granted Venezuelan citizenship to Sarah Palin - would she now be excluded from seeking the Presidency?
Additionally, birth aboard a US Naval or Coast Guard vessel is considered birth on US soil. However, if that child is born in the territorial waters of Canada, the child is granted Canadian citizenship at birth, regardless of the citizenship of the parents.
Some nations, such as Indonesia, Malaysia, and most African nations - grant automatic citizenship to any young child adopted by one of their citizens. If you were born of two US citizens, on US soil, your mother dies and your father marries a Malaysian woman, you are now granted Malaysian citizenship. Does that cancel your “natural born” status?
The only thing that should matter in a logical (and as you point out in the 1964 Supreme Court case, legal) position would be grant of US citizenship at birth. Any other citizenship granted is irrelevant as the child - and in many cases, the parents - have zero control over the granting of that citizenship.
