Primary evidence
The State Department lists these as primary evidence:
- A qualifying U.S. birth certificate
- A full-validity, undamaged U.S. passport
- A Consular Report of Birth Abroad or Certification of Birth
- A Certificate of Naturalization
- A Certificate of Citizenship
USCIS says a birth certificate provides proof of citizenship for people born in the United States, and that either a Certificate of Naturalization or a Certificate of Citizenship can serve as proof for naturalized or derivative citizens.
What a birth certificate must show
The State Department says a U.S. birth certificate must show the city, county or state of birth and a seal or stamp from that office. It must also show the registrar's signature, a filing date within one year of birth, and the parents' full names. Electronic copies are not accepted.
Secondary evidence
If you cannot provide primary evidence, the Department accepts a delayed birth certificate or a state-issued Letter of No Record, along with early public or private records from your first five years. Check the Department's current guidance, since requirements can change.
