"Dreamers" wearing their school graduation caps and gowns to show their desire to finish school in the U.S., walk to the U.S. port of entry where they planned to request humanitarian parole, in Nogales, Mexico, Monday, July 22, 2013. U.S. border officials later detained the group who asked to be allowed to re-enter the United States from Mexico on humanitarian grounds in a protest against the country’s immigration policies.
