If you only send the FBI, and wait to see if they ask for a State clearance, you risk delaying processing of your application because, if they want a State clearance they're going to send you a letter requesting it, give you 90 days to reply, and put your application on a shelf until after that 90 days is up. It's called a "bring forward date" and it's a bad thing! I always say: anything you can provide upfront that will keep them from having to contact you and ask for additional information is a step towards faster processing. Control the delays on your end . . . don't give them any opportunities to set your file aside.
