NOGALES, MEXICO - MARCH 05: Former undocumented immigrant Arturo Santana sits in front of his modest home at the Tirabichi garbage dump on March 5, 2013 in Nogales, Mexico. He said he had been living and working in Des Moines, Iowa when he was picked up and deported by U.S. Customs and Border Protection agents in 2010. He said he still has 3 children living there with their mother. About 30 families live at the landfill, searching for recyclables to sell for a living. Many have received protective gloves from the nearby non-profit Home of Hope and Peace, which plans to expand its assistance to Tirabichi residents. (Photo by John Moore/Getty Images)
