thanks for your response. Maybe i will be just getting an agency to do it on my behalf although i already completed all the docs because i don't lnow where to go after uploading all the documents. Don't even see the link where to pay it. But thanks..“Optional” means “not required”.
Am not familiar with super visa applications so I do not know.
A missing required document is the only reason I can think of, unless someone else can figure it out.
