What this form does
The last step from green card to US citizen. Median time has dropped to roughly 6 months in 2026, though the interview and oath ceremony scheduling adds time on top of the published number.
What affects the timing
Field office interview backlog drives most of the wait. Continuous residence and physical presence requirements must be met before filing; an RFE or a name match on background checks can stretch timing.
