The bill establishes new legal provisions regarding unauthorized aliens in Florida by creating Chapter 811 of the Florida Statutes, which includes sections 811.101, 811.102, and 811.103. It defines key terms such as "removal" and "unauthorized alien," and outlines criminal penalties for unauthorized aliens who knowingly enter or attempt to enter the state after evading immigration inspection. Specifically, it imposes a mandatory minimum imprisonment of nine months for first-time offenders, with increased penalties for repeat offenses. The bill also prohibits the arrest of unauthorized aliens under certain circumstances, provides affirmative defenses, and mandates that courts presume unauthorized aliens cannot be released pending trial.

Additionally, the bill introduces section 921.1426, which requires that any unauthorized alien convicted of a capital felony be sentenced to death. 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 the arrest of an unauthorized alien. The act is set to take effect immediately upon becoming law.
