Get them all out. It is too bad for them that their parents (or other questionable family members) chose to break the law, and they were too young to have a say in it. But so many of them are now late 20's and up and the smallest percentage has actually started the process to become citizens. Which the majority doesn't want to do because it would REQUIRE self deportation and then application for citizenship which still takes years to complete. They don't want to leave because their parents are still here, illegally, and they don't want to shine a spotlight on them so the parents would be deported. They also don't want to give up the welfare, etc they have enjoyed for all these years.
