DACA stands for "Deferred Action for Childhood Arrivals"
“On June 15, 2012, the Secretary of Homeland Security announced that certain people who came to the United States as children and meet several guidelines may request consideration of deferred action for a period of two years, subject to renewal. They are also eligible for work authorization. Deferred action is a use of prosecutorial discretion to defer removal action against an individual for a certain period of time. Deferred action does not provide lawful status.”
