Editor's note: While several Republicans have called President Obama's immigration overhaul plan unconstitutional, it's unclear how a court challenge to stop executive changes would fare, The Associated Press reports. A lawsuit challenging the administration's 2012 program was dismissed on technical grounds. - Stephanie

Deferred Action for Childhood Arrivals (DACA) is an American immigration policy passed by President Obama as a executive action that allows certain undocumented immigrants to the United States who entered the country before their 16th birthday and before June 2007 to receive a renewable two-year work permit and exemption from deportation. DACA confers non-immigrant legal status but does not 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. As of June 2014, U.S. Citizenship and Immigration Services (USCIS) has granted DACA status to about 581,000 people and denied to about 24,000.
In November 2014, U.S. President Barack Obama announced changes to DACA which would expand it to include undocumented 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 two years. The Pew Research Center estimated that this would increase the number of eligible people by about 330,000.
Due to a federal court order, USCIS did not begin accepting requests for the expansion of DACA on February 18, 2016 as originally planned. The court's temporary injunction, issued February 16, does not affect the existing DACA. Individuals may continue to come forward and request an initial grant of DACA or renewal of DACA under the guidelines established in 2012.
