I don’t think this is just a Florida issue. It’s a US wide one, unless there’s some states that verify citizenship of individuals forming corporations but I’ve never heard of such a thing.
This is everywhere.
That’s why I don’t hire people with their own company and speaking with much of an accent, to do any maintenance or lawn work.
I keep getting them shoving business cards in my door, though.
But if I did, there are a couple who go by “Jesus.”
