DACA stands for Deferred Action for Childhood Arrivals, a policy announced in 2012 that allows certain undocumented immigrants who arrived in the US as minors to receive a renewable two-year period of deferred action from deportation and eligibility for a work permit. To qualify, applicants must have been under 31 years of age and present in the US since 2007, among other criteria. While DACA does not provide lawful immigration status, it allows qualifying individuals to temporarily live and work in the US without fear of deportation. The constitutionality of DACA has been questioned as it was established by executive action rather than legislation.
