Hello,
If you don't mind it would help me (and others) if you could clarify as this can get really confusing! What exactly did they ask for in the RFI? Did your account look the same as the picture below and you still got an RFI?
My understanding of the process is that, upon completing the applicant's visa application and payment, the sponsor then has to complete an application (which is basically the form 40SP). To do this, the sponsor can either: create their own IMMI account and lodge an application (quoting the reference number of the applicant's visa application) OR lodge their application from the applicants IMMI account (quoting the reference number of the applicant's visa application). From what I've read, both of these options are fine. I chose the latter so that all our info was in one place. The only necessary part is to have completed both applications, one for the applicant and then one for the sponsor. Having done both applications, the sponsor will end up with two places where they can upload their documents/evidence: 1) in the main visa application's "upload documents" section (under the sponsors name) and 2) in the sponsors application under the "upload documents" section.
If your application was the same as mine, did you have to cancel the original sponsor application, create a separate IMMI account for the sponsor, and redo the sponsor application?
Thanks for any help!
