San Francisco Returns as Busiest ICE Office for Migrants on ATD
(28 Nov 2023) According to the latest detention data released by Immigration and Customs Enforcement (ICE), a total of 18,848 migrants were monitored on ICE’s Alternatives to Detention (ATD) program out of the San Francisco Area of Operations (AOR)—more than any other AOR. In second place was ICE’s Chicago, Illinois, office, which monitors 14,617 migrants and Newark, New Jersey, which monitors 14,054 migrants.

This represents a geographic shift in ICE’s ATD numbers. Until early 2022, San Francisco and Los Angeles routinely had the largest numbers of migrants on ATD, but this began to shift rapidly to Texas—specifically ICE’s offices in San Antonio, Harlingen, and El Paso—which, by December 2022, far outpaced San Francisco’s numbers. However, with the decline of migrants on ATD in Texas, San Francisco has reemerged as the AOR with the largest ATD numbers, hovering around 20,000 since the beginning of 2023.

ICE’s AORs are geographic zones of operations, each with their own ICE regional office. ICE’s San Francisco office oversees ICE activity in California north of Los Angeles. A map of ICE’s AORs is available at ICE’s website online. Although ICE reports ATD numbers by AOR, private contractors who work for BI, Inc., also carry out the everyday duties of monitoring migrants—many of whom are awaiting their day in Immigration Court.
