LOS REYES LA PAZ, Mexico (AP) — A Harvard University student stuck in Mexico for months after breaking an immigration rule was told Tuesday that he will be allowed to return home to the United States.

The U.S. Citizenship and Immigration Service had declared that Dario Guerrero Meneses, an illegal immigrant, effectively deported himself when he crossed the border without permission to accompany his dying mother to clinics offering alternative cancer treatments in Mexico.
