The main purpose of this legislation is to ensure that individuals who have been approved for U.S. citizenship through naturalization have the right to complete the final steps of the process, specifically the naturalization ceremony and the oath of allegiance. It aims to protect these individuals from being unjustly excluded or delayed from participating in the ceremony. Key provisions of the legislation include the guarantee that approved applicants can attend their scheduled naturalization ceremony, take the oath of allegiance, and receive their certificate of naturalization.
