I'm a USA citizen applying for permanent residency in Australia. As part of the form I have to say which countries I'm a citizen for, but I don't actually know...

I became a citizen through an N-600 application (my father was naturalised while I was under 18). Before then I had Canadian and South African citizenship. My understanding is that I retain my other citizenships, since I was under 18 at the time and had no say in the matter of receiving my US citizenship. Does anyone know if that is correct? Am I currently a tri-citizen, or did I lose my other citizenships in the N-600 process?

Thanks very much for your time!
