Scope and purpose
Eligible permanent residents use this application to seek U.S. citizenship through naturalization. A green card does not automatically confer citizenship; statutory eligibility must be established under the applicable naturalization provision.
Related rules and practical context
Residence, physical presence, good moral character and applicable language and civics requirements need individual analysis. INA §316 supplies the general framework, but other provisions may apply. Form N-600 concerns citizenship already acquired or derived, not the same naturalization application.
