MEXICO — Penniless and paperless when bureaucracies failed them, hopeful immigrants pound the pavement straight to the U.S. border: Migrants who had been waiting for temporary transit papers but failed to get them after waiting, some up to two months, leave Tapachula, Mexico, on Monday, Oct. 30, 2023, as they make their way to the U.S. border. The migrants said they did not have the resources to pay for more food and lodging as they wait. Photo: Edgar Clemente/AP
