This bill aims to strengthen the enforcement of immigration laws in Michigan by criminalizing the illegal entry and presence of aliens in the state. It establishes penalties for individuals who enter or attempt to enter Michigan at locations other than lawful ports of entry, with misdemeanors punishable by up to 180 days in jail and fines up to $2,000 for first offenses, escalating to felonies for repeat offenders. The bill also outlines specific circumstances under which individuals may have affirmative defenses against prosecution, such as being granted lawful presence by the federal government or being approved for certain federal programs. Additionally, it prohibits law enforcement from arresting individuals at schools, places of worship, or healthcare facilities under these provisions.

Furthermore, the bill provides legal immunity and indemnification for state and local officials, employees, and contractors involved in the enforcement of these laws, protecting them from liability arising from their actions. It includes provisions for the legal defense of these officials and reimbursement for legal expenses incurred while enforcing the law. The bill also mandates that individuals convicted under these sections must be ordered to return to their country of origin, with specific procedures for their transportation. The act is set to take effect 90 days after being enacted into law.
