What affects your wait
Service-center workload, whether USCIS issues a Request for Evidence (RFE), premium processing where available, and policy changes all move the timeline. The median means half of cases finish faster and half slower.
Approximate snapshot compiled from public sources (Boundless, Manifest Law, CitizenPath, immigration-firm trackers, and USCIS published median figures). Not live USCIS data. Figures are national-median estimates in months and vary widely by service center, field office, and case specifics. Always confirm at egov.uscis.gov/processing-times.
