McAllen, TX - APRIL 11: U.S. Office of Air and Marine (OAM), pilot Rob Smith performs a pre-flight check on an Astar B-2 helicopter before flying a patrol along the U.S.-Mexico border on April 11, 2013 in McAllen, Texas. The OAM, which assists U.S. Border Patrol agents from the air in locating undocumented immigrants and drug smugglers, has cut back flights drastically due to federal sequestration budget cuts. According to the U.S. Border Patrol, undocumented immigrant crossings have increased more than 50 percent in Texas' Rio Grande Valley sector in the last year. Border Patrol agents say they have also seen an additional surge in immigrant traffic since immigration reform negotiations began this year in Washington D.C. Proposed refoms could provide a path to citizenship for many of the estimated 11 million undocumented workers living in the United States. (Photo by John Moore/Getty Images) ( 166318833 )
