"A child born abroad to one U.S. citizen parent and one alien parent acquires U.S. citizenship at birth under Section 301(g) of the INA provided the U.S. citizen parent was physically present in the United States or one of its outlying possessions for the time period required by the law applicable at the time of the child's birth. (For birth on or after November 14, 1986, a period of five years physical presence, two after the age of fourteen, is required. For birth between December 24, 1952 and November 13, 1986, a period of ten years, five after the age of fourteen, is required for physical presence in the United States or one of its outlying possessions to transmit U.S. citizenship to the child.) The U.S. citizen parent must be the genetic or the gestational parent and the legal parent of the child under local law at the time and place of the child’s birth to transmit U.S. citizenship."

Cruz’s mother was born 11/23/34. She would have been 15 in November 1949. She lived in the US until 1960. That is 11 years after the age of 15 right there. She moved to England and returned to the US in 1966. She met Cruz father and they were married and moved to Canada to work in 69. So there was another 3 years in the states after 15.
So you agree, Ted was a citizen of the US at birth and thereby NBC?
