elite visa is good if you can spare the cash I think. Also re the volunteer visa, just recently my gf was scolded over the phone as she wanted to ask if I could get another extension (tried saving in agent fees) by a very caffeinated female immigration worker that it's not a real visa, you just pay money, etc, which I found funny. Also various immigration officers saw this visa in my passport, and they all knew that you just payed an agent, but that's the extent of it.
this is just personal speculation on my part after dealing with multiple immigration officials with this visa: they know you payed an agent to get an easy visa, but I don't think it's illegal so they can't really do anything. So, personally I think if you enter with a new passport, and do the elite visa thing, they won't give you any more issues than if you'd stayed the whole time on covid extensions, which is probably
just as dodgy.
And I'm only saying new passport because you said that's what you gonna do, but even with a new passport, all your visas, extensions and exits/entries are in their computer system, so they'll probably know all about it either way.
