An undocumented immigrant from Oaxaca, Mexico spends a night at the San Juan Bosco shelter for undocumented immigrants in Nogales, Mexico, March 9, 2013. The man, 20, who preferred not to give his name, said he was caught by the U.S. Border Patrol when he had tried to cross into the United States with a group the day before. He said he would attempt the crossing again in the upcoming days.
