# United States Immigration and Customs Enforcement **Entity class:** Federal law-enforcement agency **Domain:** Homeland security / immigration / customs / transnational crime **Doc Type:** Agency Node **Maturity:** Developed ## Definition **United States Immigration and Customs Enforcement (ICE)** is a component of the [[wiki/United States Department of Homeland Security|Department of Homeland Security]]. Its public identity is often reduced to immigration arrests and removals, but its architecture contains two different operational directorates: [[wiki/Enforcement and Removal Operations|Enforcement and Removal Operations]] and [[wiki/Homeland Security Investigations|Homeland Security Investigations]]. ERO administers the principal interior immigration-enforcement and removal mission. HSI conducts criminal investigations using customs, trade, immigration, border, export-control, financial, cyber, and transnational-crime authorities. Keeping those directorates distinct explains why an agency named for immigration and customs can also investigate money laundering, trade-based laundering, illicit procurement, terrorist facilitation, sanctions evasion, and attacks on financial or payment systems. ## Counterterrorism and Financial Reach ICE states that HSI is the largest contributor to FBI-led Joint Terrorism Task Forces and uses immigration and trade-based authorities to disrupt terrorist networks. That mission includes investigating financial and commercial activity used to finance or support terrorism. This is a jurisdictional bridge: border encounters, customs declarations, trade records, travel and identity information, and financial evidence can enter one investigation under different legal authorities. The historical [[wiki/ICEPIC|ICEPIC]] environment illustrates the analytic side of this reach. ICEPIC did not collect every record at the point of encounter. It correlated information originating in systems such as [[wiki/Treasury Enforcement Communications System|TECS]] and the [[wiki/Enforcement Integrated Database|Enforcement Integrated Database]], then exposed selected records through the [[wiki/DHS Law Enforcement Information Sharing Service|LEIS Service]]. Modern ICE architecture distributes these functions. [[wiki/Investigative Case Management|ICM]] and [[wiki/Case Management and Analytics Platform|CMAP]] hold case and workflow functions; [[wiki/FALCON Search and Analysis|FALCON-SA]] and the [[wiki/Enterprise Lakehouse|Enterprise Lakehouse]] support search and analytics; LEIS and partner interfaces handle federation; and specialized cyber, OSINT, telecommunications, commercial-data, and device-forensics services feed investigative workflows. ## Sources / Provenance - [[research/Immigration and Customs Enforcement Pattern Analysis and Information Collection (ICEPIC)|Immigration and Customs Enforcement Pattern Analysis and Information Collection (ICEPIC)]] - [ICE — mission and directorate responsibilities](https://www.ice.gov/mission) - [ICE HSI — priorities](https://www.ice.gov/about-ice/hsi/priorities) ## Relationships - **parent department:** [[wiki/United States Department of Homeland Security|United States Department of Homeland Security]]. - **criminal-investigative directorate:** [[wiki/Homeland Security Investigations|Homeland Security Investigations]]. - **immigration-enforcement directorate:** [[wiki/Enforcement and Removal Operations|Enforcement and Removal Operations]]. - **historical analytic system:** [[wiki/ICEPIC|ICEPIC]]. - **modern case and analytics platform:** [[wiki/Case Management and Analytics Platform|CMAP]]. - **functional branches:** [[wiki/FALCON Search and Analysis|FALCON-SA]], [[wiki/Investigative Case Management|ICM]], and [[wiki/DHS Law Enforcement Information Sharing Service|LEIS/LEISS]]. - **historical institutional lineage:** investigative functions of the former [[wiki/United States Customs Service|United States Customs Service]]. - **mission domain:** [[wiki/Counterterrorism|Counterterrorism]], [[wiki/Financial Intelligence|Financial Intelligence]], and transnational crime. ## ICE disambiguation and fusion route This agency is the federal-law-enforcement meaning of [[wiki/ICE|ICE]].
