The first step, the step that really matters in becoming a U.S. citizen, is becoming a permanent resident. Once you have that Green Card in hand, this country is your oyster. Become a citizen, don't become a citizen -- either way, you get to stay for as long as you like. We hear a lot about the legal path to citizenship, but what does that path actually look like? And why is it so much longer for some than for others? Has it always been like this?

Lighting the way in this episode are Allan Wernick, CUNY professor and Director of Citizenship Now, Mae Ngai, history professor at Columbia University and Margaret Chin, sociology professor at Hunter College.
