Nope. Just don't forget to include your check for the proper amount, cross all your T's and dot all your I's, and get your application notarized.
The most common delays are as a result of something in your background that may not necessarily be a disqualifying issue, but, they want more information. For example, if you had a misdemeanor 10 years ago, they might want you to obtain a certified copy of the disposition and send it to them. Stuff like that. While they do a background investigation, it appears they don't lift a finger to obtain any corroborating evidence of anything that comes up in that investigation, good or bad.
Basically, in Florida, either you qualify or you don't. Once in awhile, a hitch holds up the works, but, for the most part, you'll get your license. Unfortunately, there's little you can do from out of state to speed up the process.
I always suggest you send it return-receipt certified mail. That doesn't speed anything up, but, at least you don't sit around wondering if they actually got it or not.
OH, and BTW, there's really no such thing as an "out of state" or "non-resident" permit/license in Florida. They issue the same exact license to you that I have in my wallet. They don't even put your address on them anymore. The only thing that makes your license "out of state" is that you reside, out of state. LOL
