ICE detained several undocumented immigrants during what they believed were routine check-ins at the Intensive Supervision Appearance Program (ISAP) office in Birmingham's Southside last week. The detainees had final removal orders from immigration judges and had not complied with those orders, according to ICE officials. Immigration advocates expressed concern that targeting people in the ISAP program, which is meant to be an alternative to detention, sends a discouraging message to immigrants trying to follow the law.
