I have applied for australian PR in around Dec 2016, however case office has been allotted and therefore I have uploaded all necessary documents. I am currently on BVA (Bridging Visa - A) and waiting for their response. I would like to know if anyone can help, is that can I leave melbourne in the midst of visa processing and stay in my home country. After going back to home country, will I be able to enter if I have PR, coz I dont want to apply for BVB (I mean I dont want to come back to Australia if I don't have PR).
