They gave you a point of contact, use it. If they tell you that your security is still pending, wait, don't go calling OPM. The more addresses you have listed, the more jobs, the more complex your life is... the longer it will take. If you have questionable items on your SF85/6 you will probably not be issued an interim clearance (you know the people who go to OKC just weeks after their PEPC... they are on an interim clearance. No BI gets adjudicated in a few weeks...). You will probably have to wait for the full BI process to clear...
That might explain something else you see on these boards.
All those "so and so went to the academy, and then after being there 10 weeks they fired them for something they found in the BI"
Are those most likely people that go on interim, then something is found when the full BI is done weeks after reporting? I couldnt understand how someone could get cleared, then let go at a later time.
Obviously this isnt the first background investigation I've gone through, and I'll tell you the BI for the FAA is hardly as intrusive as some of the other agencies.
