Florida Travel

Without going into all the details. For my 16 year old son we plea bargained to unnatural act with minor under age of 16 in MA. He is on probation. He rec’d a waiver for sex offerder registery. Other than this, the kid has never done anything wrong in his life. The probation offer said Florida may require he register as a sex offender. is that correct. Florida can determine circumstances on their own and decide he must register even though home state waived?
