An undocumented immigrant who was brought to the US as a child and is a recipient of DACA ("Deferred Action for Childhood Arrivals"), a government program allowing them to stay in the country and have certain benefits (such as the ability to obtain permits to work legally). The term is derived from the DREAM Act, in which "DREAM" is an acronym for "Development, Relief, and Education for Alien Minors." The Dreamers remain a constant source of debate in Washington.
