@John *********
I'm not sure I'm getting your meaning.
Typically you pay at the end, after all the documents have been processed, passports stamped, etc.
Whereas "accepting application" means "success", I understand you have to pay. I'm asking if I still have to pay if my application is denied (specifically for the extension).
A more practical question is — do I pay upfront, do I attach the money to the application, etc.?
If so, I can see them potentially keeping it. If not, I struggle to see them asking for payment *after* they just denied me.
