Well, some good news...
Received my GCMS notes requested back on Jan 3. They were generated Jan 12. Last entry is on Jan 11. Notes show it's gone up for officer review on that day. Whoever did eligibility review states they're satisfied it's a genuine relationship. My original FBI report shows an arrest, but it was a mistake and was expunged. I sent them a new copy of my FBI report showing that it's clear now, but there's plenty of notes about it. At least I know they received the new one.
Since then, background check went "In Progress", so the officer review must have gone OK? Here's hoping the FBI report stuff doesn't cause a hangup.
I have an alert tone on my iPhone for CIC email. Got all excited that I had the DM email, until I started reading it further. Oh well. My wife says it was a dress rehersal for the real thing. Hopefully I'll see that soon?
