If he's coming off a retirement visa and bouncing to get back in on a visa exempt, it's going to raise flags, when it's easier to get a 12-month extension.
Yeah. A lot of "lucky" people using a "lucky" immigration office....or maybe, just maybe the biggest immigration office in the country knows how to do it correctly? Maybe it's the pisspot provincial offices where staff want to feel superior and implement their own rules.
I have to put my hand up and accept responsibility for the meltdowns going on in this thread. About 2-3 years ago I put this method to the test. Two years on OA, returned to Australia for a few months, then came back on visa exempt, which I immediately converted to 90-day non-O, followed by 12-month extension, and did not require the 800k lump sum, as CW immigration accepted my 65k transfers (continuous) in lieu of the income affidavit. I posted this on "the other" visa group and had my post removed by one of the then mods, and was subsequently booted from that group for "spreading misinformation". However, subsequently another of the mods, Tod Daniels, investigated further and actually went to CW to confirm if what I was saying was correct. He was advised that it was correct, and Tod did post to that effect. Unfortunately because I had been removed from the group I cannot access this post. In the meantime I received a number of PMs from other group members eager to learn how I'd done this, and subsequently many have replicated what I did. Sadly, people (such as yourself) and others who believe they are "experts" have tried to downplay and negate what I (and others) have done, and are now embarrassed by their obvious lack of knowledge, and will say "well you were lucky". Yeah, all those that have done it are "lucky", or maybe, just maybe, we found the loophole, and you're all mightily pissed off. Live with it guys, there's some out there smarter than you
