What Is Form N-400 (Application for Naturalization)?
Form N-400 is used by lawful permanent residents (green card holders) to apply for U.S. citizenship through the naturalization process.
Naturalization is the process by which an individual becomes a U.S. citizen after meeting certain eligibility requirements established by U.S. immigration law.
This process typically includes submitting Form N-400 to U.S. Citizenship and Immigration Services (USCIS), attending a biometrics appointment, completing an interview, and passing an English and civics test, unless an exemption applies.
Who May Apply?
Common situations include:
• Lawful permanent residents who have held a green card for at least 5 years
• Individuals married to a U.S. citizen who may qualify under the 3-year rule
• Individuals who meet continuous residence and physical presence requirements
• Individuals seeking to become U.S. citizens through the naturalization process
Each case is unique and eligibility may depend on several factors, including immigration history, travel history, and other requirements.
If you are unsure whether this process applies to your situation, you may wish to review your case with a licensed immigration attorney.
