The Constitution recognizes only two classes of American citizens: Natural born and Naturalized. This third class of citizen, "native born" or "just plain citizen" is nothing more than Birther mythology.
From Scalias concurrence in Miller v. Albright:
The Constitution contemplates two sources of citizenship, and two only: birth and naturalization. United States v. Wong Kim Ark, 169 U.S. 649, 702 (1898).
