States by Immigration Activity

California has the largest immigrant population in the U.S., driven by proximity to Mexico, established diaspora communities, and a strong economy attracting employment-based immigrants. The state accounts for roughly 17% of all U.S. immigration activity.

State totals include all immigration categories: green card adjustments, naturalizations, nonimmigrant arrivals, asylum grants, and refugee resettlements attributed to each state based on the applicant's intended residence.
