Hello, so I have a de facto visa PR skilled independent 189. But after moving to Australia after a few months my partner and I separated as he wanted to go back to the UK and I wanted to stay. I am the second applicant on the visa and am really worried I am going to get asked to leave. Q1. Will I get asked to leave? Q2. Do I need to inform immigration? Q3. If I don't need to inform immigration will this affect my citizenship application? Please help....
