After the USCIS approves your Form N-400, Application for Naturalization, they will automatically schedule you to take the Oath of Allegiance at a naturalization ceremony. Taking the Oath means you complete the process of becoming a U.S. citizen!
What to expect during your naturalization ceremony:
You will first receive a notice to take the Oath of Allegiance.
After this, you are able to participate in a naturalization ceremony during the same day as your interview. In cases when a ceremony is unavailable, USCIS will be the one to mail you a notice with the date, time, and also location of your scheduled naturalization ceremony on a Form N-445.
In cases you are unable to participate in your scheduled naturalization ceremony, you should return the notice, Form N-445, Notice of Naturalization Oath Ceremony, to your local USCIS office specifying a new date and explaining why you cannot attend the scheduled naturalization ceremony. If you fail to appear more than once for your naturalization ceremony it can lead you to a denial of your application.
After you check in at the Ceremony a USCIS officer will be the one to carefully review your responses to the questionnaire, Form N-445, Notice of Naturalization Oath Ceremony. You need to complete your responses to the questionnaire before you arrive at the ceremony.
Then, you must return your Permanent Resident Card to USCIS officer when you check in for your naturalization ceremony. Until you take your Oath of Allegiance at a naturalization ceremony, you are not a U.S citizen.
