I need more proof. Can the rest of the country actually SEE that passport?
One birth certificate will work as well - no?
It is quite possible and not infrequent to obtain a US passport without a US birth certificate. You only need two things for a passport application besides your photo: proof of identity and proof of citizenship. The proof of identity most commonly used is a photo driver’s license. The proof of citizenship most commonly used is a birth certificate, but naturalization papers are fairly common also. Secondary birth evidence such as baptismal certificates, hospital birth records, medical records, early census reports, elementary school transcripts, insurance records, family Bible records, or newspaper articles announcing the birth can also be considered when accompanied by affidavits of personal knowledge completed by an older blood relative with personal knowledge of the birth of the applicant. So no, a birth certificate is not required to get a US passport.
Foriegn people who become citizens get a US passport.
