I just did my 1 year retirement extensionv2 hours ago and wasn't given any form to take away. I was asked to sign something (as well as every page of paperwork submitted) but I wasn't shown what it was. Maybe it will be given to me when I pick up my PP tomorrow.
I couldn't believe all the pages from PP and bankbook that I had to submit, there must have been 20 pages all up. The immigration officer wanted to see my old bankbook with the 800K from 10 years ago, which I no longer have, it's bureacracy gone mad.
