My 18-year-old daughter was born in the USA to a German citizen (her father). We moved to Australia when she was 6 months of age and she became naturalised as a dual US/AU at about 5. She has spent time in Europe with her German family and would like to move to Germany for university when she graduates. She doesn't want her US citizenship, but would like to keep her Australian citizenship, as her sister and I still live here, plus she has friends etc.
If she first revoked her US citizenship, then applied for German citizenship, how can she keep the Australian one? I know it is possible but my question is, how? For example, if she had an apartment in her name, would she be able to use real estate ties as a reason.
Or, can she, through her father, somehow obtain permanent residency there, and would that be easier?
