U.S. authorities have halted mobile app appointments to admit asylum-seekers at a Texas border crossing after advocates warned U.S. authorities that migrants are being extorted there. Customs and Border Protection has not said what prompted the decision to stop scheduling appointments via the CBP One app for the crossing in Laredo, Texas. The change went into effect June 3. Migrants told The Associated Press that Mexican immigration officials across the Texas border in Nuevo Laredo took their travel documents. They say the officials threatened to make them miss their scheduled asylum appointments if they did not pay them.
