Which document confirms citizenship after naturalization?

• A. Certificate of Citizenship
• B. U.S. Passport
• C. Green Card
• D. Certificate of Naturalization

Answer: (D)

The main idea is recognizing the official proof of citizenship after completing the naturalization process. When you naturalize, the government issues a Certificate of Naturalization as the formal, legal document that confirms you are now a U.S. citizen. This certificate is the specific proof of citizenship from the naturalization process and is what you’d use to, for example, apply for a U.S. passport or update records.

A U.S. Passport, while it can serve as evidence of citizenship, is issued after you have the citizenship—so it isn’t the immediate document that confirms it. A Green Card shows lawful permanent resident status, not citizenship. A Certificate of Citizenship covers people who derived or acquired citizenship (through parents or birth abroad), not those who naturalized. So the Certificate of Naturalization is the document that confirms citizenship after naturalization.
