I'm a little confused.

What state are you currently in? I find it very odd that you would not be allowed to take the drivers test in that state, just because you don't currently have a license in your home country. Each state is a little bit different, but that doesn't sound quite right to me.

Is there any reason you've picked Florida to get your license? Is it just because it seems like that would be the easiest place? I've never heard of a state allowing someone from another state to get a Drivers License, so I would agree that having a Florida license will pretty much be a requirement.
