Who is most often responsible for fining a PPO for I-9 violations?

The Department of Homeland Security (DHS) is responsible for enforcing immigration laws in the United States, including the regulations related to the Form I-9, which is used to verify the identity and employment authorization of individuals hired for employment. When a private security organization, such as a Private Patrol Operator (PPO), fails to properly complete I-9 forms or violates employment eligibility verification rules, the DHS has the authority to impose fines and penalties.

This responsibility stems from the DHS's role in overseeing immigration compliance and ensuring that employers adhere to labor laws regarding the legal status of their employees. The other choices do not have a mandate related to employment verification; the Department of Transportation focuses on transportation and safety regulations, the Federal Bureau of Investigation handles criminal investigations, and the California Department of Fair Employment and Housing deals with discrimination and employment rights but does not enforce immigration laws.
