Reporting Online

Visit the U.S. Immigration and Customs Enforcement online tip form at ice.gov. Section I of the form allows you to include your name, email and phone number. This is optional, however, and you can omit it if you wish to remain anonymous. Under section II select "Employment/Exploitation of Unlawful Workers" and select that the complaint involves a business or company. Provide the details about the company hiring undocumented workers in section III. Provide the location of the business and include a summary of up to 2,500 characters giving as much information as you have about the undocumented workers at this business.
