Since when? Both parents must be citizens of the US at the time of your birth. They can be naturalized, but the must be citizens. nd if your parents were naturalized citizens, but worked for the government, or the military, and were stationed overseas where you were born, you'd be a natural born citizen too.
Serously? Ever heard of the phrase "anchor baby?"
Read the 14th Amendment to the Constitution:
"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside."The constitution says nothing about the citizenship of the parents.
