Allender Ruy (R), poses for a picture with friends while waiting for a train in the site known as El Basurero, a stretch of land next to a trash dump and the railroad, as they continue their journey to the U.S. border, in Huehuetoca, State of Mexico, Mexico May 4, 2023. Ruy played voice messages on his phone from a friend warning him about the several-day journey ahead: "Brother, when you get the train, bundle up ... it's very cold, terribly cold." After being deported to Venezuela earlier this year from Panama while en route to the U.S., Ruy was hoping for a second shot. "I have to get there, at the latest, before the 11th," he said.
