Once your application for naturalization has been approved, USCIS will schedule you for your naturalization ceremony. At this ceremony, you will take an oath of allegiance to the United States, completing the process of becoming a United States citizen. Once your application has been approved, USCIS will send you a form N-445 form providing you the date and time of your naturalization oath ceremony. At the ceremony, you will relinquish your green card and take the oath of allegiance. After the ceremony, you will receive your certificate of naturalization and can apply for a U.S. passport, register to vote, and update your social security record.
