  • The applicant’s US citizen parent regularly resides outside the US (use Form N-600K instead)
  • The applicant was born before their parents were married, the applicant did not become a US citizen before their 16th birthday and the applicant’s father is their only parent who is a US citizen
  • The applicant wants to replace a lost or stolen citizenship certificate (use Form N-565, Application for Replacement Naturalization/Citizenship Document instead)
  • The applicant has submitted Form N-600 in the past and was rejected

What Evidence is Needed as Part of an N-600 Certificate of Citizenship Application?

For an N-600 Certificate of Citizenship application to be accepted, the applicant must include evidence of their citizenship status. The following forms of evidence must be included in an N-600 application.

Birth & Marriage Certificates

The applicant’s birth certificate must also be included in the application. The birth certificate of the US citizen parent of the applicant must also be included. A marriage certificate for the applicant’s US citizen parent is also required, as is a document proving marriage termination (such as divorce certificate or death certificate), if applicable.

Proof of US Citizenship

Certificate of Citizenship applicants must also include proof of their US citizenship. Examples of accepted proof of US citizenship may include:

  • US birth certificate
  • Form N-550 (Certificate of Naturalization)
  • Form N-560 (Certificate of Citizenship)
  • Form FS-240 (Report of Birth Abroad of United States Citizen)

  • School, job or military records
  • Deeds, mortgages or lease documents that prove residence
