There are eight to 10 million undocumented immigrants in the United States, all of whom are central to the heated immigration debate in Washington D.C.
More specifically, there are undocumented immigrants who are part of a mixed family - in which one family member is undocumented while the rest of the family are American citizens.
"It's a horrible tragedy and a national shame, but looking on the bright side, [mixed families] have reframed the debates and things are finally looking like something might happen on immigration reform in Washington," said David Koelsch.
Koelsch is an immigration lawyer and a professor at the University of Detroit Mercy Law School.
"You can talk about the eight to 11 million [undocumented immigrants], but all of those people have loved ones and employers...it has a much broader effect in our society and economy beyond just those people," he said.
