His parents may not have applied for one, one of Cruz’s spokespeople said his Mother registered him at the consulate when he eas born. She may have added him to her passport, so she could travel back to her parent’s. The CRBA is not a required document to prove citizenship
That’s the entire point of a CRBA — to document that a person holding it is in fact a citizen because they were born to a citizen parent who held citizenship at the time the birth occurred even though they were not in the United States. If his mother did indeed register him at the US consulate at birth he would have received a CRBA and he also would not have received Canadian citizenship as Canada did not recognize dual nationality at that time, not until 1977. Further, there is possible evidence that his mother was registered to vote in Canada. To be registered to vote one must of course be a citizen. If she took Canadian citizenship her birth certificate is immaterial because at the time she gave birth to Ted she was Canadian, not American. As this is a CIVIL case there is no ‘presumption of innocence’ only a probability (50.1%) that the accusation is true. Produce a CRBA and all of this goes away.....unless of course he is holding it back for maximum political benefit.
How Adult Children Born Abroad to American Parents Can Prove U.S. Nationality
What happens if you were born abroad, but you still have a claim to U.S. citizenship? You may have acquired your U.S. citizenship at birth because your parents (or even just one parent) are U.S. citizens and fulfilled certain U.S. residency or military service requirements. The laws dictating which children can acquire U.S. citizenship automatically have changed frequently throughout the years. For more information, please see Nolo's section, "Acquiring or Deriving Citizenship Through Parents."
If you were eligible to acquire U.S. citizenship at the time of your birth, your parent or guardian may, ideally, have registered your birth with the Department of State or the nearest U.S. embassy or consulate and received a document which can be used to prove your nationality. These types of documents include:
FS-545, Certification of Birth (issued by the Department of State prior to November 1, 1990)
DS-1350, Certification of Report of Birth (issued by the Department of State prior to December 31, 2010), and
FS-240, Report of a Birth Abroad of a U.S. Citizen (currently issued by all U.S. embassies and consulates).
The Department of State no longer issues FS-545 or DS-1350 certifications, but those documents are still considered valid proof of U.S. citizenship and can be used to apply for a U.S. passport or to demonstrate work authorization. U.S. embassies and consulates now issue a very official-looking FS-240 certificate to U.S. citizens whose parents register their foreign birth.
