CNMI Department of Corrections (Susupe, Saipan) — sole ICE contract detention site in the Northern Mariana Islands
Overview
The CNMI Department of Corrections (DOC) in Susupe, Saipan is the only ICE detention facility in the Commonwealth of the Northern Mariana Islands and the only contract detention site in the territory. It is a Commonwealth-government jail (the Vincente Taman Seman building) that holds local pretrial detainees and sentenced inmates alongside a small number of ICE administrative detainees. ICE’s San Francisco Field Office holds custodial authority; the local ICE/ERO presence is the Saipan ERO Sub-Office, (670) 237-6000.
This is a coverage gap in the detention pipeline — CNMI had no prior KB entry — and it is a genuinely small operation: ICE has explicitly said it has no plans to build a dedicated detention center in the CNMI. People held by ICE longer than ~12 hours are transferred to this DOC facility in Susupe rather than to any standalone ICE site.

Why It Matters
This is the federal immigration detention chokepoint for an entire U.S. commonwealth with a uniquely large guest-worker (CW-1) and tourist population. Even at single-digit-to-low-double-digit ICE headcounts, it is the only place in the CNMI where ICE detainees are held, and its average daily population roughly quintupled from 2022 (~4) to 2026 (~18-21) as national detention hit record highs (>73,400 nationwide on a single day in mid-January 2026). The same facility was the subject of a June 2025 CNMI Advisory Committee (USCCR) report on healthcare access in the territory’s justice system, raising standing concerns about conditions in a remote, single-jail jurisdiction.
CNMI Immigration Context (do not apply mainland assumptions)
The CNMI controlled its own immigration until the Consolidated Natural Resources Act of 2008 (CNRA) extended most U.S. immigration law to the islands; the transition period (begun Nov. 28, 2009) now runs through Dec. 31, 2029. A CNMI-only transitional worker visa (CW-1) supports the labor force, with the cap shrinking to 8,000 (FY2026) and 5,000 (FY2029) before the program sunsets. ICE/CBP/HSI presence in the islands is tied to this transition and to the Marianas’ role as an Asia-facing transit point (see the overview note and the HSI Mariana Islands BEST task force).
