The law signed by Gov. Ron DeSantis makes it a state crime to enter Florida after coming into the United States illegally and to re-enter the state following deportation.

The law, enacted this year, made it a crime for unauthorized migrants to enter the state. Challengers say immigration is a federal matter.

Under the law, known as SB 4-C, anyone who “knowingly enters or attempts to enter [Florida] after entering the United States by eluding or avoiding examination or inspection by immigration officers” can be convicted of a first degree misdemeanor.
