the McCarran-Walter Act, the Immigration and Nationality Act of 1952
Public law 82-414 Chapter 1 Section 301 (7)
This applies to Obozo, assuming he is the son of Barrack H. Obama, Sr. and that he was born abroad.
If born abroad with the stated father, he is not even a U.S. Citizen.....
Precisely. Stanley Ann was not of sufficient age to confer citizenship on Barry, if he was born outside the territorial US, and if BHO Sr. was his father.
That was the law, at the time of his birth.
