ICE raids generally are the results of months (or even years) of investigation by Homeland Security Investigations (HSI). Before a “raid” is conducted, a search warrant must be issued. To obtain a search warrant, HSI must show that facts establish probable cause to believe that there are violations of federal law, i.e., the company is willfully and unlawfully employing illegal aliens.
