In this Oct. 23, 2018 image, people seeking asylum in the United States line up to receive a number at the border in Tijuana, Mexico. The first obstacle that migrants in a giant caravan may face if they reach the U.S. border is a long wait in Mexico. To enter through San Diego, the wait in Mexico is a month or longer.
