Can I maintain permanent residency of another country?

I am a permanent resident of Australia. If I get a US green card can I also maintain my permanent residence in another county? THANKS.

Maybe. The US does not strictly forbid permanent residents from having permanent residence in another country. However, there are limitations on how much time you can spend outside the US as a permanent resident, so these requirements may make it difficult for you to maintain your permanent residency in another country.

I don't think being a permanent resident of another country is an issue. I know some people who have successfully applied for their green cards while also being permanent residents of countries in Europe.

What about paying taxes? Do I need to report my taxes from Australia?

I'm pretty sure it depends on the other country. For most part, the US doesn't seem to care however many PR/citizenships you have. But some other countries don't allow dual, so you should check with their embassy
