US immigration policy has become one of the most contentious issues in American politics, but there is one point on which most of us agree: our immigration policy is broken. And while the sheer number of interests involved mean that an easy fix is unlikely, the best place to start is with a sound understanding of how we got the immigration system we have today. As a historian of immigration who currently serves as Director for the Americas and Europe at Refugees International, Yael Schacher has a particularly well informed perspective on this issue. In this episode, Yael walks us through the history of immigration policy in the US and shares what she sees as the major challenges that stand in the way of reforming our current immigration system.
