SB 3 amends the state's immigration control law to require contractors and subcontractors to have been using E-Verify (i.e., an Internet based system that allows employers to determine the eligibility of their newly hired employees to work in the United States) for at least six months before entering into a contract with a county. Contractors and subcontractors who file false affidavits regarding compliance with the E-Verify requirement may be convicted of a felony and are subject to a fine up to $1,000 and/or one to five years imprisonment. All other violations are misdemeanors. SB 3 also requires suppliers and subcontractors on county projects to submit their affidavit declaring compliance to the county.
