Answer 1

Form N-400 is the application for obtaining US Citizenship (naturalization). The Form N-400 is used by Lawful Permanent Residents (green card holders) over the age of 18 who meet the eligibility requirements to apply for Citizenship.

A completed Form N400 (Citizenship Application) has to be filed along with photos and supporting documents. A green card holder who is above 18 years of age and meets other eligibility requirements can file N400 form. Becoming a U.S. citizen has many advantages including the right to vote and the ability to sponsor relatives to come to the United States.
