Florida domicile people do you stay 6 months there?

If you reside for more than 6 months in Florida or any state you could be classified as a resident. In Florida anyway it's unlikely that the state would notice. But you can get Drivers License, get Florida tags, change your address and register to vote in an afternoon and become a resident no matter how long you stay in the state.

If you are wealthy or pay a lot of taxes then some states will definitely notice how long you are in the state. Blue watches you.
