"US Law very clearly stipulates: “If only one parent was a US 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."The person that wrote this article fails to clarify, the above is in play ONLY IF THE CHILD IS BORN OUTSIDE THE U.S.
So far no one has given us proof of that yet.
