DACA stands for Deferred Action for Childhood Arrivals. It an immigration policy created by the Obama administration in June 2012 after DREAMer students has been acknowledged as people who were largely (not all) raised in the United States. This policy allows some people who entered the country as minors and either entered or remained in the United States illegally to receive a two-year renewable period of deferred action from being deported and also to be eligible to be granted a work permit.
There were approximately 800,000 individuals who signed up for the program created by DACA. As of 2017, however, the DACA was rescinded by the Trump administration through the Memorandum on Rescission of Deferred Action for Childhood Arrivals (DACA) dated September 05, 2017.
