Prior to 1934, U.S. citizen mothers could not transmit U.S. citizenship to children born abroad; only U.S. citizen fathers could do that. In 1994, Congress passed the Immigration and Nationality Technical Corrections Act, which added INA 301(h) (8 USC 1401(h)) which granted citizenship to people born abroad to a U.S. citizen mother before 1934:
The following shall be nationals and citizens of the United States at birth:
(h) a person born before noon (Eastern Standard Time) May 24, 1934, outside the limits and jurisdiction of the United States of an alien father and a mother who is a citizen of the United States who, prior to the birth of such person, had resided in the United States.
This section was specified to apply retroactively to the date of the person’s birth.
