Revocation of immigration status after immigration

I'm not talking about you. You really don't even understand the basic concepts. You are still from China after emigration, but you can live in Canada permanently. For people with Canadian nationality, you are just a foreigner who has lived in their country for a long time.

People with Canadian citizenship are Canadian citizens, and you used to be an immigrant.

As an immigrant, you can't work in a government department or run for election. You are very different from a citizen.

But of course you are free to return to China, because you are still a citizen of China.

I don't know if you understand.
