Are you still waiting for your 801?
I submitted mine in June 2019 and wait patiently.
The 820/801 process is two stage, wait for 2 years (probation period i call it) then submit the 801.....the 801 should ideally and fairly be processed within 1 month....have waited/done probation for 2 years....why have to wait up to another two years ....just because of insufficient immigration staff. Once the 801 is submitted, it should get priority processing!
I did all my 300/820/801 online, with the 801, when I submitted it online, it showed as "submitted" but then on the second day it showed "being processed". I do not think it's actually been processed so why the status shows that, i'm very confused.
