Immigration can be a controversial topic. We all want safe, secure borders and a dynamic economy, and people of goodwill can have legitimate disagreements about how to fix our immigration system so that everybody plays by the rules.

But that's not what the action that the White House took today is about. This is about young people who grew up in America -- kids who study in our schools, young adults who are starting careers, patriots who pledge allegiance to our flag. These Dreamers are Americans in their hearts, in their minds, in every single way but one: on paper. They were brought to this country by their parents, sometimes even as infants. They may not know a country besides ours. They may not even know a language besides English. They often have no idea they're undocumented until they apply for a job, or college, or a driver's license.

Over the years, politicians of both parties have worked together to write legislation that would have told these young people -- our young people -- that if your parents brought you here as a child, if you've been here a certain number of years, and if you're willing to go to college or serve in our military, then you'll get a chance to stay and earn your citizenship. And for years while I was President, I asked Congress to send me such a bill.

That bill never came. And because 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.

But today, that shadow has been cast over some of our best and brightest young people once again. To target these young people is wrong -- because they have done nothing wrong. It is self-defeating -- because they want to start new businesses, staff our labs, serve in our military, and otherwise contribute to the country we love. And it is cruel. What if our kid's science teacher, or our friendly neighbor turns out to be a Dreamer? Where are we supposed to send her? To a country she doesn't know or remember, with a language she may not even speak?
