Ariel G. Ruiz Soto

Ariel G. Ruiz Soto is a Senior Policy Analyst at MPI, where he works in the U.S. Immigration Policy Program and the Latin America and Caribbean Initiative.

His mixed-methods research examines how governments across the Western Hemisphere design, coordinate, and implement migration policies, as well as how those policies affect foreign- and native-born populations. He also analyzes sociodemographic trends used to estimate the unauthorized immigrant population in the United States, helping to inform evidence-based policy debates.

He writes regularly on immigration enforcement, migrant reception and reintegration, and asylum and refugee policy in the United States, Mexico, and Central America. He is a co-author of On the Move: Migration Policies in Latin America and the Caribbean (Stanford University Press, 2025), which examines how host countries in Latin America and the Caribbean have responded to large-scale and uneven migration flows.

Mr. Ruiz Soto holds a master’s degree from the University of Chicago’s School of Social Service Administration with a focus on immigration policy and service provision, and a bachelor’s degree in sociology from Whitman College.
