TIJUANA, Mexico — Several dozen more Central American immigrants were called into the United States on Wednesday morning, putting them one step closer to their goal of receiving asylum. A total of 49 people have now been admitted to the San Ysidro Port of Entry. With an estimated total of about 150 caravan participants who have traveled from Central America to Tijuana, it appears that about a third of the total have been accepted into the system. Organizers from the caravan, known as Pueblo Sin Fronteras, gathered in the middle of their makeshift tent city to call out the latest names Wednesday morning with the help of a loudspeaker as they huddled under an umbrella to shield them from morning showers. Dozens of immigrants surrounded Alex Mensing, one of the organizers, as he called out each name.
