I hadn't realised the processing times were quite so long - will keep fingers crossed! GOES application made yesterday (using existing Disclosure Scotland/PVG clearance cert). Will be going through quite a few US airports at the end of Oct so hopefully be in a position to have an interview by then and should be able to find a slot somewhere. From what I've read on some blogs they also seem to be reasonably flexible about taking folk earlier if they've got a space so hopefully it'll be do-able around the constraints of flight timing.
