At least seven states, including Texas, Oklahoma and Iowa, have passed similar laws in recent years. All are blocked for now or have not yet taken effect.

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.
