Here is the online system to check if you have pending tickets with the Florida Government.

[Florida Traffic Tickets][1]

By the way I suggest you contact someone there to help you with the process before come to US. The website told you:

In Florida, you may have several options to pay your traffic ticket, including:

 - Online. 
 - By mail. 
 - By phone. 
 - In person.
