The proposed 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 such offenses, with enhanced penalties for repeat offenders. It also includes provisions that prohibit 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 severe penalties for unauthorized aliens who re-enter the state after being denied admission or deported, including mandatory minimum sentences based on prior convictions. It specifies that unauthorized aliens are not eligible for civil citations or diversion programs and mandates that law enforcement agencies notify relevant authorities upon the arrest of an unauthorized alien. Furthermore, the bill stipulates that unauthorized aliens convicted of capital felonies must receive a death sentence. Overall, the legislation aims to strengthen enforcement against unauthorized immigration in Florida.
