only one way for the US government to remove a citizenship of a foreign nation, "naturalization".<quoted text>
Yes our constitution does not recognize dual citizenship status. That means that it ignores the fact that Obama was a dual citizen at birth and accepts only the fact that he was a US citizen at birth due to his place of birth. Oh, and Woodrow Wilson was also a dual citizen at birth, USA/Britain, due to the fact that his mother never relinquished her British citizen status despite becoming a US citizen by marriage.
Yep, she did become a citizen through marriage, the citizenship of the father was all that counted.
