Law Enforcement Assistance Corner

The Law Enforcement Assistance Corner is an index of U.S. Immigration and Customs Enforcement (ICE) information for federal, state, local and tribal law enforcement agencies. This corner provides information on ICE's work in immigration and criminal law enforcement and the many ways they overlap. It pulls together links from the website to ensure that ICE's law enforcement partners can easily find relevant information in support of their mission and any current or future collaboration with ICE. In addition, the Law Enforcement Assistance Corner features two information sharing systems designed to allow the federal government to communicate sensitive information to state, local and tribal law enforcement agencies. This site has been designed as a tool to make exploring the work of ICE as easy as possible.
