We can accept only certain documents as proof of U.S. citizenship . These include : Certification of Report of Birth DS-1350, Consular Report of Birth Abroad FS-240, U.S. passport, Certificate of Citizenship N-560/N-561, and Certificate of Naturalization N-550/N-570
Also since my kid doesn't have a passport what else would be acceptable?
we may accept the child 's State - issued non - driver 's identification card  or an Adoption decree
