there is not a lot of clear info on this , and nothing asked about having to show it again , but seem some other reports saying you need to keep it in ...but nothing official.
Basically my visa just said 5 years multiple entry
asked when I was due to arrive and what flight and when leaving again (don't know why). But never asked for proof .. asked for address but not for proof ...only all the basics you see on the adverts for it
well you never know, that asked for a list of work .. or something like that , If not happy they will email you and let you upload a new document. I got it the second time
no comment or I'll get banned again , I was getting sick of the keyboard clowns in the group on other posts ...and I asked on a DTV post about the document the guy put in as he didn't want to show his tax info ( fair enough) but someone jumped in and was trying to be smart .. so I said something I shouldn't have apparently 🙈
