TIJUANA, Mexico (AP) — A Mexico-born Harvard University student who was stuck for months in his native country after crossing the border without permission will have to wait a little bit longer to return to the United States.

Dario Guerrero Meneses, who was brought into the U.S. illegally at age 2, was granted a visa in Tijuana early Monday and had expected to pick it up in midafternoon but was told it wasn’t yet ready.
