Unfortunately, there is no evidence to suggest that the parent or parents of Ted Cruz ever filed a Consulate Report of Birth Abroad (CRBA) form with the U.S. Government in or around 1970, which is why Ted Cruz released a copy of his Canadian citizenship records and not any U.S. citizenship records.

At present, all FOIA (Freedom of Information Act) requests filed in search of any U.S. citizenship documents to confirm the true official U.S. citizenship status of Ted Cruz have been denied access. All citizenship records for Ted Cruz are sealed unless and until Ted Cruz agrees to allow any such records to be released by either U.S. or Canadian agencies.

As a result, there remains no authentic evidence to support the claims that Ted Cruz is either a “natural born” or “naturalized” citizen of the United States.

It does seem that way, doesn’t it?

FWIW, Cruz's citizenship status would have been certified in a FS-545, if obtained before 1990. Same function, different form, different name of the form, "Certification of Birth Abroad".

According to the U.S. Citizenship and Immigration Services, those who automatically acquire citizenship are not required to obtain any such certificate.
