I finally got GCMS notes today and need to spend some time deciphering this thing. But from a glance, it is seems criminality check is complete and security check is on going...
I think you already guessed that part correctly. Don't read too much into the notes....Just give you headache !
As you know the security check will take some time but i'm sure you will hear something from them as it approaches 12 months.
Not much you can do, so have some Baijiu and wait it out.
