This bill prohibits employers from knowingly employing illegal aliens and mandates E-Verify. The bill provides that for a first violation, the court must order the employer to terminate all illegal aliens' employment and submit a signed sworn affidavit to that effect or face suspension of business licenses by appropriate agencies. The bill provides that for a second violation, defined as a violation occurring during a probationary period for a previous violation, the court must order the permanent revocation of the employer's business licenses. Additionally, Employers receiving economic development incentives from the state must register and participate in E-Verify, providing proof of compliance or potentially repay all incentive funds received. The Secretary of State must request and publish online a list of Iowa employers registered with E-Verify every three months.
