A naturalized citizen can qualify for a U.S. passport.
My children were born in England while I was stationed there and I obtained a certificate of birth from the Embassy. I consider them NBC so I am not a birther nut. What bothers me is the mystery of whether or not Cruz is NBC and that I suppose hinges on whether or not his mother became a Canadian citizen before Ted was born.
Until I know for sure I cannot in clear conscience vote for Cruz even though I like him very much. Equally disturbing is Cruz stating that he was unaware of his dual citizenship status prompting him to renounce Canada when he decided to be a Senator.
You know what, that completely missed my view! Duh! You are correct, the only evidence that will establish citizen at birth is either a CRBA, or a Certificate of Citizenship.
-- Until I know for sure I cannot in clear conscience vote for Cruz --
I'm confident he'll produce his CRBA when it best suits his needs. You can't be the only one who "wonders," and most in that spot will accept that a CRBA = NBC.
Regarding the possibility of Cruz’ mom getting Canadian citizenship before Ted was born:
Not possible.
She wasn’t in Canada long enough; she had been there only 4 years when Ted was born, and the requirement was 5 years.
