Good question. The PDA has had my 199 since 07 SEP, and my PEBLO and OMBUDSMAN are checking the status and to see if they can speed it up (I'm supposed to be starting a position on Post with a contractor this month, hmmmm lol ). I called the PDA directly last week, and after receiving the obligatory lecture about how I need to go through my PEBLO, the person could only confirm that they've had my 199 since 07 SEP, are backlogged, and will process as soon as possible. He did state that if you have a written job offer, the PEBLO can submit it with a memo and they will try to expedite, not sure if that helps you or not.
Hope yours goes fast, hang in there.
