SEATTLE - Some neighborhoods throughout Mexico City continue to hold large encampments of migrants seeking asylum in the United States.
Until late August, the Mexican capital was the southernmost point from which migrants could register to request an appointment to seek asylum through the U.S. Customs and Border Protection's mobile app known as CBP One. The geographic area where the app is available was expanded to include Mexico's southernmost states since, but many migrants who made the journey before then have stayed in the capital city while they wait to get an appointment.
