Good that you ordered GCMS, at least will help calm down your nerves.
General Maxim - as long as no ADR, the longer in the battle to gain PPR, the better coz eventually you will get it.
Now the difficult part - how to wait and win the war of attrition ( mental more so). Well its my personal take so different people can have different opinions. If you have done your best, there is nothing more you can. If it has to happen it will. Even if it does not, no one can take away anything from you. You are still unique, still the best, still the fighter. Happiness is not in getting a PR or citizenship of a certain country. Just life your life enjoy doing what makes you happy. Don’t push the pause button on your happiness just coz the application status is on a pause. If you have come 4 months into the process only 1% chances of rejection. Even death has a higher probability. Do you fret n loose sleep over it?
( just my approach to the application. No calls No notes No panic. Just wait for my time!)
