if the address associated with your Mastercard/visa is not used when making online payment, it won't work. I knw in canada, postal code should match. Hope it helps.
Well PNP would take you atleast 5 months to nominate.. so i dnt think that's worthful..
I have been nominated by ontario, applied for wife's open work permit application, after being rejected twice for her visit visa
Being the principal applicant in Canada, you must have send the medical documents of your wife to Ottawa. Hope this helps.
Pls do update if you have received any response from CPP-O
