Acquisition of U.S. Citizenship by a Child Born Abroad
http://travel.state.gov/law/citizenship/citizenship_5199.html
A child born abroad to two U.S. citizen parents acquires U.S. citizenship at birth under section 301(c) of the Immigration and Nationality Act (INA) provided that one of the parents had a residence in the United States or one of its outlying possessions prior to the child’s birth. The child is considered to be born in wedlock if the child is the genetic issue of the married couple.
Section 301(c) does not, and cannot re-define the meaning of "natural born citizen" as it was used in Article II of the US Constitution.
But here is the bigger point. Why would you want anyone to have the ability to re-define what the words in our constitution mean?
If you accept that constitutional meanings can be re-defined, what are you going to do when someone re-defines arms as "slingshots"?
"Section 301(c) of the Congressional Gun Control act (CGCA) defines "Arms" as any group of small rubber band powered slingshots capable of pestering people."
Changing word meanings is not so harmless is it? I urge you to think carefully about the danger of letting people change the meaning of Constitutional words.
