Hi I’m new to this forum I hope I’m putting this in the correct section. I am an Australian citizen currently in the U.K.. Myself and my British partner want to move to Perth. We haven’t submitted a partner visa Application as yet we are hoping to do that next April however I’ve done a bit of research and I’ve come across some sites that say I now have to apply to become a sponsor before we put in our partner application. Is this the case ? There is lots of conflicting information on this. I’m hoping someone can point me in the right direction TIA
