International migration can contribute importantly to sustainable economic growth. The effects of migration for both origin and host countries, however, depend on immigrant integration. We experimentally evaluate the impact of information and migrants’ aspirations on immigrant integration using a field experiment among Cape Verdean immigrants in Portugal. The interventions promote integration outcomes such as migration status regularization and better-quality employment of migrants. They furthermore affect those left behind. While the impact on material remittances is muted, targeting migrant integration barriers improves democratic processes and attitudes over gender equity in origin countries. In addition, providing immigrants with better information sources about integration processes affects migration intentions and expectations of prospective migrants.
