Deferred Action for Childhood Arrivals (DACA) is an American immigration policy which allows certain undocumented immigrants who entered the country before their 16th birthday and before June 2007 to receive a renewable two-year work permit and exemption from deportation. It does not confer legal immigration status or provide a path to citizenship. It was started by the Obama administration in June 2012. At the program's start, the Pew Research Center estimated that up to 1.7 million people might be eligible. , U.S. Citizenship and Immigration Services (USCIS) has granted DACA status to about 581,000 individuals and denied to about 24,000. In November 2014, U.S. President Barack Obama announced changes to DACA which would expand it to include illegal immigrants who entered the country before 2010, eliminate the requirement that applicants be younger than 31 years old, and lengthen the renewable deferral period to three years. The Pew Research Center estimated that this would increase the number of eligible people by about 330,000.
