If USCIS grants me naturalization, when will I become a citizen?

citizenYou become a citizen as soon as you take the Oath of Allegiance to the United States in a
formal naturalization ceremony. In some places, you can choose to take the Oath the same
day as your interview. If that option is not available, or if you prefer a ceremony at a later
date, USCIS will notify you of the ceremony date with a “Notice of Naturalization Oath
Ceremony” (Form N-445).
