The agency has an annual budget of approximately $8 billion. With increased I-9 audits and unannounced workplace raids by ICE and other law enforcement agencies making news, it is critical for employers to know their rights and responsibilities and to formulate both preventive policies and a responsive action plan in the event of an ICE raid. For employers, ICE has a worksite enforcement program that investigates both administrative and criminal violations of businesses and their employees here and overseas. ICE generally conducts two types of worksite investigations: (1) an audit of an employer's I-9 practices and (2) a worksite enforcement action, commonly referred to as a raid, of employers suspected of employing undocumented workers. For an I-9 audit, ICE will often arrive at a worksite unannounced and demand to see the employer's I-9 forms. Employers have three days to comply with the demand for the I-9 forms.
