Yeah, it's totally unbelievable. If we're talking about an extension based on retirement, the paperwork is exactly same every year. When I've done my extension I go to Kodak Express and take copies for 1 year ahead, everything I need. Then I can put together a set of copies for immigration when I need it. In 30 seconds. It might be a 90 days report or next extension.
Yes, really. If we're not talking about an advice face to face. Even if you meet every requirement they will charge you for putting together a pile of documents for immigration.
I said "should" because that's the official requirement if you know what official means. One day before is allowed at several immigration offices. Where I'm staying it's allowed because some bank branches open 10am, while immigration open 8:30. Read this slow and you might understand.
