4. December 24, 1952 to November 13, 1986
If, at the time of your birth, both your parents were U.S. citizens and at least one had a prior residence in the United States, you automatically acquired U.S. citizenship with no conditions for retaining it.
If only one parent was a U.S. citizen at the time of your birth, that parent must have resided in the United States for at least ten years, at least five of which had to be after the age of 16. There are no conditions placed on retaining this type of citizenship.
Since Stanley Anne Dunham was only 18 at the time of Obama's birth, she could not have resided in the USA for 5 years after the age of 16.
Why all the hoopla about a "Birth Certificate"? :lol: :lol: :lol:
