I applied for PR PR in Australia six years ago, but I didn't live in Australia for two years in the first five years, but my mother has permanent residency in Australia. How to calculate PR?

You have PR, you can stay in Australia as long as you want if you don't leave the country, but if you want to leave Australia and come back, you have to get a visa without an Australian passport. In this way, when you get your first visa, it will be a five-year round trip. In these five years, there is no rule on how many days, one day, two days or five years you will stay. However, if you want to come back within five years, you must return to Australia before the visa expires.

Five years after your return, if you want to leave this country, you need a second PR visa at this time. The time for the Immigration Bureau to grant you a second PR visa depends on how long you have lived in Australia within five years of the first visa. If you have lived for two years, you will be granted a five-year multiple-entry visa. If not, you will usually be given a three-month round-trip visa.

If you become an Australian citizen, you don't need a visa to travel to and from Australia. It doesn't matter how many days you stay in Australia. As long as you go to America for less than three months, you don't need a visa. Only China needs your visa.

In addition, China does not recognize dual citizenship, while Australia does.

Besides, there is no tax in China.

Taxes, PR and citizens in Australia are the same.
