I am looking for advise for the easiest / quickest option to move my Mom out here to Australia from the UK. I have my PR and going though my Citizenship now; my sister is also here and has her PR we are the only children and both live here. My Mother is retired and wants to be here with us and her grandchildren she has no other family in the UK. Please can someone offer us some advise on this or can recommend a great Immigration agent that can help us - we are based in Sydney. Much appreciated!
