Key aspects of naturalization include:

Eligibility: To be eligible for naturalization in the United States, an individual must meet certain requirements, including being a lawful permanent resident (green card holder) for a specified period of time, typically five years (or three years if married to a U.S. citizen), demonstrating good moral character, being able to speak, read, and write basic English, and passing a civics and history exam on U.S. government and history.
Application: Eligible individuals must file Form N-400, Application for Naturalization, with U.S. Citizenship and Immigration Services (USCIS). The application must be accompanied by supporting documents, such as proof of lawful permanent residency, evidence of continuous residence and physical presence in the United States, and any waivers or exceptions to the requirements.
Biometrics appointment: After submitting the naturalization application, applicants are typically scheduled for a biometrics appointment at a USCIS application support center, where their fingerprints, photograph, and signature are collected for background checks and identity verification.
Interview and examination: Applicants are required to attend an interview with USCIS, during which they are tested on their knowledge of English and civics. The English language test assesses the applicant’s ability to speak, read, and write in English, while the civics test evaluates their understanding of U.S. history, government, and civic principles. Applicants must also demonstrate their ability to understand and take the Oath of Allegiance to the United States.
Oath of Allegiance: Upon successfully completing the naturalization process, applicants attend a ceremony where they take the Oath of Allegiance to the United States, renouncing allegiance to any foreign country and pledging allegiance to the United States. By taking the oath, individuals formally become U.S. citizens and are granted all the rights and responsibilities of citizenship.
Certificate of Naturalization: After taking the Oath of Allegiance, individuals receive a Certificate of Naturalization as official documentation of their U.S. citizenship. The certificate serves as proof of citizenship and enables individuals to apply for a U.S. passport, register to vote, and obtain other benefits and privileges of citizenship.
