A 23-year-old activist who surrendered to U.S. immigration authorities as part of a protest calling for reform and a halt to record deportations has been deported to Mexico. Rocio Hernández Pérez was brought to the United States by her parents at the age of four. She was one of the so-called Dream 30 who crossed into Laredo, Texas, in September. The Dream 30 took action after another group of young people, the Dream 9, made a similar crossing in Arizona in July. The Dream 9 were released and cleared an initial hurdle to receive asylum. But a number of the Dream 30 remain in detention, with some facing possible deportation. Meanwhile, the head of the U.S. Border Patrol says the agency arrested roughly 420,000 people in the most recent fiscal year, a 15 percent increase from last year.
