Green Card Citizenship Timeline

Summary

A green card holder married to a U.S. Citizen can apply for U.S. Citizenship through naturalization after 3 years of marriage, provided they have been a lawful permanent resident for at least 3 years. The applicant must have lived in marital union with the U.S. Citizen spouse and resided continuously in the U.S. For at least 3 years. Since the individual in question has been a lawful permanent resident for 10 years, they meet the residency requirement and can proceed with the application after 3 years of marriage, assuming all other conditions are satisfied.
