Senior Policy Analyst

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.

    A Post-Title 42 Vision for Migration Management Comes into Focus

    Facing a dramatically different reality arriving at the U.S.-Mexico border with the end of a pandemic-era policy that resulted in more than 3 million expulsions, the Biden administration unveiled a policy vision that marries expanded legal pathways with stiff consequences for those seeking to enter without authorization.

    El número récord de encuentros con migrantes en la frontera México-Estados Unidos encubre la historia más importante

    Los titulares enfocados en la cifra récord de 2,4 millones de migrantes encontrados en la frontera México-Estados Unidos durante el año fiscal 2022 encubren la historia más importante: Los flujos migratorios se han diversificado rápidamente más allá de México y el norte Centroamérica, y como resultado, las políticas de control migratorio son incongruentes con la realidad de hoy. Esto demuestra la evidente necesitad de nuevos enfoques regionales, argumenta este comentario.

    Headlines focusing on the record-breaking nature of the 2.4 million migrant encounters at the U.S.-Mexico border in fiscal year 2022 overlook the much bigger story: Migrant and asylum seeker flows have rapidly diversified beyond Mexico and northern Central America and as a result, U.S. enforcement policies are misaligned. Today's reality sharply underscores the need for new regional approaches, this commentary argues.
