Dreamers--undocumented immigrant youth who came to the United States as children--make up a small share of total immigrants, but they contribute immensely to the nation's success. Among the 11 million undocumented immigrants living in the U.S., over 3.2 million came before turning 18 and have lived in the country for at least four years. For many of these immigrants, the United States is the only country they have ever known. They have grown up as Americans and attended the nation's schools. However, Dreamers' lack of legal immigration status has created barriers to postsecondary education and economic mobility. Improving access to traditionally underserved students, particularly immigrant youth, would help the country meet its growing workforce demand and close gaps in college completion. This brief provides an overview of the Dreamer population, the Deferred Action for Childhood Arrivals (DACA) success and challenges, and the various legislative proposals currently in Congress. The brief concludes with recommendations for improving the economic security of immigrant youth and adults through expanded access to adult and postsecondary education.
