How to find out if you are an immigrant?

You can find it as long as you don't cancel your domestic household registration. But China is a nation. Once the China government finds out that you have other nationalities, the China government will ask you to give up one of them.

The entry-exit administration department can check all entry-exit records according to the passport. However, the probability of finding a name may be small. After all, China is overpopulated, and there are many people with the same name.

I need to bring my ID card to the entry-exit administration to check the entry-exit records. If it weren't for me, it would be even harder.
