What's the difference between successful immigration and naturalization?

Let me tell you the difference. Australia is an example.

"Green Card" = "Permanent Residence Status"

Permanent residence is often called PR. Permanent residency is a right that allows people with permanent residency to live permanently in the country and enjoy the same treatment as citizens in many aspects.

In fact, the permanent right of abode in Australia is embodied by the Zhang Yongjiu residence visa affixed to the passport of the original country of residence. A permanent residence visa not only allows you to live in Australia permanently, but also allows you to travel to and from Australia freely and indefinitely within five years. At the same time, Australian permanent visa holders are free to settle in New Zealand and enjoy all the rights of the New Zealand green card. From the welfare policy, the holders of new permanent residence visas are not allowed to apply for unemployment relief, emergency comprehensive relief and student allowance in the first two years, and other welfare benefits are the same, such as free primary and secondary education, student loans and free medical care. You can enjoy all benefits if you hold a green card for 2 years.

Permanent residents have different rights from citizens.

The difference between Australian permanent residents and citizens' rights is mainly reflected in five aspects: first, the right to vote; The second is the right to be elected; The third is to join the army; The fourth is to be elected as a member of the jury; The fifth is to engage in some special work of the government (such as intelligence personnel). These five rights or obligations are not for permanent residents, but for citizens.
