The culmination of the naturalization process is the administration of the Oath of Citizenship.
Northern District of Iowa, approximately 600 petitioners take this oath in a formal ceremony each year. The ceremony may be held at the Federal Courthouse or a nearby designated site. The ceremony typically lasts for approximately one hour. Cameras are allowed in the courthouse for this ceremony only. There will be time to take pictures after the ceremony.
