Deferred Action for Childhood Arrivals (DACA) is a U.S. immigration policy that allows certain undocumented immigrants who entered the country as minors to receive a renewable two-year period of deferred action from deportation and eligibility for a work permit. Established in 2012 by the Obama administration, DACA aims to provide temporary relief to individuals who meet specific criteria, emphasizing the importance of their contributions to society and the economy.
