You’ll attend an interview at USCIS. An officer will ask questions about your background, test your English and civics knowledge.

Step 4: Decision

USCIS will approve, deny, or request further evidence (an RFE).

Step 5: Oath ceremony

If approved, you’ll attend a naturalization ceremony and take the Oath of Allegiance, becoming a U.S. citizen.
