Tell the oxygen thief to get her facts right.
A dual citizen is a person who is a citizen of 2 or more countries.
You become a dual citizen if you: are an Australian citizen, are granted citizenship of another country and don't lose your Australia citizenship, or
remain a citizen of another country and become an Australian citizen
Australia allows a person to have dual citizenship. Some countries do not. To find out, you can check with the relevant embassy or consulate.
