What is the primary purpose of Form N-400?

The primary purpose of Form N-400 is to serve as the application for naturalization, allowing individuals to apply for U.S. citizenship. This form is critical for lawful permanent residents who meet the eligibility requirements to become U.S. citizens.

The naturalization process involves several steps, including demonstrating good moral character, proficiency in English, and knowledge of U.S. history and government. Completing Form N-400 initiates this process, enabling applicants to provide the necessary information and documentation to USCIS to determine their eligibility for citizenship.

In contrast, options relating to refugee status, visa extensions, or work permits involve different forms and processes. Refugee status is sought using Form I-590, visa extensions typically require Form I-539, and work permits are applied for with Form I-765. Each of these forms serves a distinct purpose within the immigration system, separate from the naturalization process encapsulated by Form N-400.
