This study examines immigrant integration through the lens of community-based organizations. Based on interviews with nonprofit leaders and an analysis of data from the National Center for Charitable Statistics, the study found that immigrant-serving nonprofits provide a wide range of programs and services to foreign-born communities which promote the social and political mobility of newcomers. Findings also suggest a potential spatial mismatch between immigrant-serving organizations and the people they serve. The organizations are concentrated in the metropolitan area while immigrant populations are growing in the outer suburbs. Moreover, different political and administrative structures and policies affect the ability of these nonprofits to serve their constituents.
