Submit the PCC upfront,,, i would say not to pay RPRF upfront, because when they ask for it, you will k ow your application is moving and almost final.I am a november applicant and got AOR in February and medical in March but since now they did not ask me for landing fee or PCC.
I know cases are different but I see that most guys received the the landing fee demand at very first stages or along with their medical... wanted to know if I should get worried!
My medical was requested 4 months after AOR and my RPRF after 4 months of medical.
