Do the United States and Australia recognize dual citizenship?

New immigrants retain their original nationality after becoming Australian citizens, but they cannot apply for other nationalities after becoming Australian citizens, otherwise you must give up Australian citizenship.

The Australian government abolished the Australian Citizenship Act 1948, Chapter 17, and allowed dual citizenship from 20 18 without restriction.

American law does not force people with dual nationality to choose between the two nationalities. At the same time, if a person automatically acquires another nationality, it will not affect his American citizenship. However, if a person "voluntarily" and "chooses" to apply for the identity of another nationality and intends to give up American citizenship, he loses American citizenship.
