U.S. Agents Take Undocumented Immigrants Into Custody Near Tex-Mex Border

MISSION, TX - JULY 24: A Salvadorian minor carries her family's passports after crossing the Rio Grande from Mexico into the United States on July 24, 2014 in Mission, Texas. Like most of the recent surge of Central American immigrant women and children, her family brought documents to prove their nationality to U.S. Border officials. Tens of thousands of immigrant families and unaccompanied minors from Central America have crossed illegally into the United States this year and presented themselves to federal agents, causing a humanitarian crisis on the U.S.-Mexico border. Texas' Rio Grande Valley has become the epicenter of the latest immigrant crisis, as more of them enter from Mexico into that sector than any other stretch of the America's 1,933 mile border with Mexico.
