From the Dallas Morning News, Dec. 28, 2013.
Ted Cruz says he’s hired lawyers to renounce Canadian citizenship
Snip
When Cruz was born, his parents were living in the Canadian oil patch in Calgary.
His mother is a native-born American. His father, a Cuban émigré who later became
a naturalized American, was still a Cuban citizen.
Under U.S. law, a child born with even one American parent is automatically
entitled to citizenship, even if the birth takes place outside the country.
Canada, like the United States, also confers automatic citizenship to anyone
born on its soil, regardless of the parents’ nationalities.
That revelation by The News startled Cruz and his parents.
His mother, he said, had understood that it would have taken an affirmative
act to claim Canadian citizenship, and that’s what she’d told him as a child.
“There was no reason to retain counsel to analyze Canadian law, because it
wasn’t relevant to anything I was doing,” he said.
