I am changing employer on a 482 short term visa. My visa is valid till Oct-2021. I stopped working for my old employer in mid-December'2020. My new employer filed the application for change in sponsorship on 27th January'2021. Still no response from the department & today is 4th Feb. My 60 days get over on 13th Feb. 1. As per the department website, a new nomination needs to be 'LODGED' before 60 days. Does it need to get approved within 60 days as well? 2. Do I need to inform the department personally as well that I have stopped working for my previous employer?
