The dates and locations of naturalization oath ceremonies are generally available on United States District Court websites, such as the Central District of California website’s Naturalization Ceremony Locations and Schedule section, and the United States District Court Southern District of New York website. Ceremony times, days and locations vary throughout the year in the Central District of California, whereas a district judge presides over a naturalization ceremony each Friday at the Ceremonial Courtroom for the Southern District of New York.
According to the official website of the Department of Homeland Security and the U.S. Citizenship and Immigration Services section, the USCIS schedules an Oath of Allegiance ceremony for all applicants successful in their Form N-400 Application for Naturalization and determines the location of that ceremony. Some candidates participate in a naturalization ceremony on the same day as they pass their interviews. In the event that a ceremony is not available, USCIS mails the candidate a notice that reveals the location, date and time of his scheduled ceremony. This is known as a Form N-445, a Notice of Naturalization Oath Ceremony.
There are two types of ceremonies: a court-administered judicial ceremony and a USCIS-administered administrative ceremony. Candidates receive a Certificate of Naturalization after they take the Oath of Allegiance, states USCIS.
