Dreamers aren't people born in this country to immigrant parents, those people are called citizens. Dreamers are people who were born elsewhere, but brought here when they were very young, who are legally allowed to stay in the country. Unfortunately by signing up for said program they created a list that Trump will likely use to find and deport them, even though many of them only speak english and have lived most of their lives in the US often believing they were US citizens.

If Trump isn't going to arrest and deport Dreamers then why is Daniel Ramirez Medina sitting in detention in Seattle?
