RESUMEN
Migration to the United States is an intricate part of Puerto Rican life ever since Puerto Rico became a colony of the United States in 1898. Our review of literature on Puerto Rican migration to the United States reveals that this migration is primarily associated with cycles of economic turmoil that result from over a century of U.S. colonialism in Puerto Rico. We also discuss how the pre- and post-migration context Puerto Ricans face influence their mental health. Emerging theory suggests that Puerto Rican migration to the United States should be conceptualized as colonial migration. Within this framework, researchers argue that U.S. colonialism in Puerto Rico not only creates the conditions that help explain why Puerto Ricans migrate to the United States but also the circumstances they encounter upon migration.
