As the culmination to the naturalization process, applicants for citizenship take the final step of becoming a citizen by pledging the Oath of Allegiance to the United States. The Oath is taken once the applicant has gone through the process of submitting a Form N-400, Application for Authorization, passing the FBI background check, and successfully passing the interview and tests with the United States Citizenship and Immigration Services (USCIS). Depending on the location of the final interview and exams, successful applicants may take the Oath either the day of the interview. Other applicants will receive a Form N-445, Notice of Naturalization Oath Ceremony, from USCIS by mail indicating the scheduled time of their oath ceremony. The Oath requires the applicant for naturalization to promise three things. First, he must renounce all foreign allegiances. Second, he must swear to support and defend the principles of the Constitution and the laws the United States. Lastly, he must promise that when called upon he will serve the United States by fighting in the U.S. Armed Forces, performing noncombatant service in the U.S. Armed Forces and performing civilian service for the United States. Once the applicant has sworn the Oath of Allegiance, he is a full citizen with all of the rights, responsibilities and benefits of a U.S. Citizen.
