MISSION, Texas (AP) — Overwhelmed and underprepared, U.S. authorities are releasing migrant families on the Mexican border without notices to appear in immigration court or sometimes without any paperwork at all. U.S. immigration authorities say court notices often take hours to prepare and describes the move as a way to save time. The rapid releases ease pressure on the Border Patrol and its badly overcrowded holding facilities but shift work to Immigration and Customs and Enforcement, which enforces immigration laws within the United States. Migrants are now being told to report to ICE within 60 days.
