Almost 800,000 undocumented youth in the United States applied for the Deferred Action Program for Childhood Arrivals (DACA), which will turn three years old June 15.

Since the implementation of the program in 2012, a total of 794,501 "dreamers" applied for the protection from deportation and 381,188 have received it, according to USCIS.

The program started by the Obama administration allows undocumented youth who meet certain criteria to also receive a work permit. 

At the program's start, the Pew Research Center estimated that up to 1.7 million undocumented youth might be eligible.

Last year, President Obama announced two executive actions intended to offer a relief to an additional 5 million undocumented immigrants. 

The first one would expand the deferred action program for undocumented youth (DACA) implemented in 2012 by allowing an additional number of "dreamers" to apply for a protection from deportation and a work permit. The second one, known as DAPA, would allow parents of American citizens or residents to apply for the same protections.

However, the future of the expansion of DACA remains uncertain after the 5th U.S. Circuit Court of Appeals in New Orleans, Louisiana, denied the Obama administration’s request to lift a hold on the president’s executive actions on immigration.

The court denied the petition to lift the hold established in February by a federal judge in Texas, Andrew Hanen, following a lawsuit by a coalition of 26 states.
