I have applied visitor visa extension for my mom thru online .
I got the reciept number.
I didnt send any documents yet becoz they said in letter I will be notified later if anythink else they need.
my question is how are the chances of getting extension of my mom visa with out sending documents.

As they have said, they will contact you if they need additional documents. In that case, you should wait for them to contact you.

As online visa extension is so new, not much experiences or history is available.
