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 ICE.gov 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.

Criminal Justice Stakeholder Forms

ICE ERO is dedicated to ensuring the public is fully informed of the agency's immigration enforcement efforts. In support of the agency's mission, ICE ERO is committed to transparency, collaboration and resolving concerns with external stakeholders, particularly the agency’s criminal justice partners.

While executing its mission, ICE takes enforcement action against aliens who may also have obligations within the criminal justice system. These actions may conflict with state or local criminal justice proceedings, which may create a need for additional information sharing with state and local authorities.

For example, an alien may miss a court hearing and forfeit bond money or be absent from a meeting with a parole officer and be subject to penalties as a result.

ICE developed our ICE Criminal Justice Stakeholder Forms to offer criminal justice professionals access to relevant and reliable information from ICE when working with aliens in these circumstances. The information provided through the information request process can be used to verify that the alien’s absence from court or other failure to meet a criminal justice obligation was due to ICE enforcement, detention, or removal.

If you require information on an individual who failed to meet a criminal justice obligation and you suspect it was the result of ICE immigration enforcement:

  • Call the ICE ERO Detention Reporting and Information Line at 1-888-351-4024 and ask the operator for a criminal justice stakeholder Request Form.
  • Complete and submit your Request Form to ERO.INFO@ice.dhs.gov or via standard mail.
  • ICE ERO Detention Reporting and Information Line personnel will process your request and issue a Certification Form, which, if approved, will provide the requested information.
