The bill establishes new legal provisions regarding unauthorized aliens in Florida, creating Chapter 811 of the Florida Statutes. It defines key terms such as "removal" and "unauthorized alien," and outlines criminal penalties for adult unauthorized aliens who knowingly enter or attempt to enter the state after evading immigration inspection. The bill mandates minimum imprisonment terms for various offenses, including a minimum of 9 months for first-time offenders and up to 2 years for repeat offenders. It also prohibits the arrest of unauthorized aliens under certain circumstances, provides affirmative defenses, and requires courts to detain unauthorized aliens pending trial for specific violations.

Additionally, the bill introduces enhanced penalties for unauthorized aliens who re-enter the state after being denied admission or deported, with mandatory minimum sentences ranging from 1 year and 1 day to 5 years, depending on prior convictions. It specifies that unauthorized aliens are not eligible for civil citations or diversion programs and mandates that law enforcement agencies notify federal immigration authorities upon arrest. Furthermore, the bill stipulates that unauthorized aliens convicted of capital felonies must receive a death sentence. The act is set to take effect immediately upon becoming law.
