“…it made no sense to expel talented, driven, patriotic young people from the only country they know solely because of the actions of their parents, my administration acted to lift the shadow of deportation from these young people, so that they could continue to contribute to our communities and our country. We did so based on the well-established legal principle of prosecutorial discretion, deployed by Democratic and Republican presidents alike, because our immigration enforcement agencies have limited resources, and it makes sense to focus those resources on those who come illegally to this country to do us harm. Deportations of criminals went up. Some 800,000 young people stepped forward, met rigorous requirements, and went through background checks. And America grew stronger as a result.”
From Obama’s letter on DACA.
