“Other pieces in the puzzle. Have we ever seen Cruz’s birth certificate? Did he register for the US draft? Have we seen the certificate issued saying he is a US citizen?”
Cruz’ birth certificate says he was born in Canada. He was automatically registered for the selective service when he applied for a federal grant for college. We have not seen a CRBA (Consular report of birth abroad) that his mother should have applied for when he was born. We have not seen his passport.
We have seen his mother’s birth certificate, but we do not know for sure if she became a Canadian citizen like his father.
Also, when he was born, Canada did not recognize dual citizenship. It wasn’t until 6 years later. We know he was a dual citizen, because he gave up his Canadian citizenship about 2 years ago.
At that time, wouldn't he have had to show authorities proof of when and how he became a US citizen?
