I believe cruz’ dad was a Mexican citizen when Cruz was born.
His mom was an American citizen when Cruz was born.
They were working in a business in canada at the time of cruz’ birth.
But his parents were married, and it looks like his mom was old enough and lived in the u.s. long enough (5 yrs past her 14 th birthday.)
But those dates have to be checked.
Then check what changes were made (other than eliminate quotas) to the 1952 INA rules.
Cruz' father was a Cuban refugee, who had been captured and tortured by Castro.
