Certificate of Citizenship (Form N-600)

A Certificate of Citizenship is official proof that a person is a U.S. citizen by law, usually acquired through a U.S. citizen parent. It is commonly requested for individuals who became citizens automatically at birth or after entry to the United States but never received formal documentation.

The application is filed using Form N-600 with U.S. Citizenship and Immigration Services. This certificate provides permanent evidence of citizenship and is often required for obtaining a U.S. passport, government benefits, employment verification, or other legal purposes. Proper documentation and careful preparation are essential to avoid delays or denials.
