Until 1952, if a child was born to a U.S. Citizen and an alien parent, the citizen parent had to have resided in the US or its outlying possessions for 10 years, at least 5 of which were after attaining the age of 16 (so the parent had to be 21).
After 1952, a child born to a U.S. Citizen and an alien parent, the citizen parent had to be physically present in the US (or outlying possessions) prior to the child’s birth for 10 years, at least 5 of which were after the age of 14 (so the parent had to be 19).
