Thanks but...and this is the tricky part...the actual application consists of my part (sponsor) and her part (principal applicant).Never had to link an account. As far as I know, she needs her own account.
1. Do we both need to link our respective parts of our application through separate online profiles?
The guide says, that it is the sponsor who has to send the application. There are four payments to be made: sponsorship fee, principal applicant processing fee, right of permanent residence fee and OWP fee. I will be paying all that through my account.
2. Do I, as a sponsor need to pay first two payments and she as the applicant last two payments?
