@Gundrukay thanks for the info. i'll give it try.

@Jonny, are you speaking from personal experience? if so can you elaborate?

if you read the documentation (link i posted in original post) it clearly says

"Failure to submit all required documentation may result in the refusal of your application or
processing delays."

and it lists that "Proof of intention to return to that country" needs to be established via "airline tickets, travel itineraries".
