"Since FY2004, Congress has appropriated funding to the Department of Homeland Security’s(DHS’s) Immigration and Customs Enforcement (ICE) for an Alternatives to Detention (ATD) program to provide supervised release and enhanced monitoring for a subset of foreign nationals subject to removal whom ICE has released into the United States. These aliens are not statutorily mandated to be in DHS custody, are not considered threats to public safety or national security, and have been released either on bond, their own recognizance, or parole pending a decision on whether they should be removed from the United States. Congressional interest in ATD has increased in recent years due to a number of factors. One factor is that ICE does not have the capacity to detain all foreign nationals who are apprehended and subject to removal, a total that reached nearly 400,000 in FY2018. (ICE reported an average daily population of 48,006 aliens in detention for FY2019, through June 22, 2019.) Other factors include recent shifts in the countries of origin of apprehended foreign nationals, increased numbers of migrants who are traveling with family members, the large number of aliens requesting asylum, and the growing backlog of cases in the immigration court system."
