If we start by applying offshore (309/100) then he comes to Australia and stays, can we change the visa over to an 820/801or does it have to be a brand new application?
Thank you.You can't change it. If you apply for the 309/100, there's no bridging visa so he'd need a valid visa to come to Australia if the 309 hasn't been granted yet. If he wants to make an onshore application, that means doing it all over again and paying a new fee.
