    MPP implementation began at the San Ysidro port of entry on or about January 28, 2019 with the intention that MPP implementation would expand eventually across the southern border. Prior to MPP, an asylum seeker at the border, upon demonstrating a credible fear of persecution, was permitted to wait in the U.S. pending their removal hearing and asylum adjudication.
