USCIS Form N-600, Application for Certificate of Citizenship

About USCIS Form N-600

Form N-600, Application for Certificate of Citizenship, is filed by a person who is already a US citizen and wants official proof of that status. It is commonly used by people who became citizens through a US citizen parent, either at birth abroad or after birth while under eighteen. The certificate documents citizenship that already exists rather than granting it.
