The bill enacts a new subpart in the Louisiana Revised Statutes, specifically addressing unlawful entry and reentry into the state by aliens. It defines key terms such as "alien," "unlawful entry," and "unlawful reentry," and establishes penalties for these offenses, including imprisonment and fines. The bill outlines that a first offense may result in up to six months of imprisonment or a fine of up to one thousand dollars, while subsequent offenses can lead to one to two years of imprisonment and fines up to ten thousand dollars. Additionally, it provides affirmative defenses for individuals who can prove lawful presence in the state or that their actions do not violate federal immigration laws. The bill also prohibits the abatement or termination of prosecutions based on immigration status determinations.

Furthermore, the bill authorizes the governor to negotiate an interstate compact aimed at enhancing border security and deterring unlawful entry into Louisiana. This compact is intended to facilitate cooperation among states to manage illegal immigration effectively. The legislation emphasizes the need for mutual assistance among states to address the challenges posed by illegal immigration, which it claims threatens the safety and security of Louisiana citizens. The provisions of the bill are designed to take effect under specific circumstances, including decisions by the U.S. Supreme Court or amendments to the U.S. Constitution that would enhance state authority over immigration matters.
