🇺🇸 United States · Guide
A structured summary of publicly documented naturalisation or citizenship routes, residence conditions, application steps and official sources. Meeting a residence period never means citizenship is automatic.
Only records with complete current review coverage and official sources are shown.
The main naturalisation route for lawful permanent residents generally requires five years as an LPR, continuous residence, the required physical presence, residence in the USCIS district, good moral character, English and civics requirements, and an oath. Five years alone does not automatically create US citizenship.
Timing：Check the official residence-period rule.
View settlement route and official sources →An eligible lawful permanent resident married to and living in marital union with the same US citizen spouse may use the three-year naturalisation rule rather than the general five-year rule. The citizenship, marital-union, residence, physical-presence, character, English and civics conditions must continue through the applicable stages.
Timing：Check the official residence-period rule.
