Deferred Action for Childhood Arrivals

The Deferred Action for Childhood Arrivals (DACA) was an American immigration policy that allowed some individuals who entered the country as minors, and had either entered or remained in the country illegally, to receive a renewable two-year period of deferred action from deportation and to be eligible for a work permit. 
As of 2017, about 800,000 individuals—referred to as Dreamers after the DREAM Act bill—were enrolled in the program created by DACA. The policy was established by the Obama Administration in June 2012 and rescinded by the Trump Administration in September 2017. In November 2014 President Barack Obama announced his intention to expand DACA to cover additional illegal immigrants. But multiple states immediately sued to prevent the expansion, which was ultimately blocked by the courts.
