As I said to you, a person who is a citizen "at" the time of birth is not a person who becomes a citizen "subsequent" to the time of birth.
A person who becomes a citizen "subsequent" to the time of birth is a "naturalized citizen". A person who is a citizen at the time of birth is "natural born".
Read section A of 1401. Then read section H.
Most of us are covered under Section A as natural born. Others such as Cruz are covered under Section H.
Now, as I told another poster, if you want to claim that USC 1401 is unconstitutional, then have at it. BUT USC 1401 in and of itself makes Cruz an NBC.
Your issue is with the law, not me.
Was Cruz born before noon (Eastern Standard Time) May 24, 1934?
