Then how did he get into the country in the first place? Immigration would not let a baby into the country without a passport.
Sure they would. In those days a baby was put on to its mother's passport. That could be done at the US Embassy or Consulate. Since we haven't seen any passport of Stanley Ann's or BHO's, how do we know whats on it? Someone does though, the someones who broke into the passport files of BHO, Hillary and McCain.
If the country was Canada, they could have just driven accross the border, no questions asked, except perhaps of the driver. August of 1961 was decades before September of 2001. Things Were Different Then.
