One of the things we were excited to investigate when we went to Alabama was to answer the question at the heart of the immigration debate: what does it cost taxpayers when we let in millions of immigrants, documented and undocumented? In Albertville, how much was it? We asked economist Kim Rueben and her colleague Erin Huffer to run the numbers.

In 2012, the fever broke, and the Albertville city council stopped targeting Latino residents. The mayor says he and the council are taking a cue from the public schools.

Brian Reed continues his story about the town of Homer, Alaska. He talked to all sorts of people involved in the debate over whether the town should welcome immigrants.

In the first half of the show, we documented a community that was worried about what might happen, theoretically, if undocumented immigrants arrived. In this act, Producer Zoe Chace looks at a community where the immigrants have already arrived – Rockville, Maryland.
