Do immigrants need their own consent?

No application is required. Immigration overseas is divided into different situations. For example, some people only get foreign green cards and have permanent residency abroad. And some people will choose to give up their China nationality and join other nationalities.

It is understood that some areas, such as Guangzhou, will require immigrants to cancel their accounts at the police station when they immigrate overseas; Under normal circumstances, as long as you don't join the household registration of other countries, you can keep your own household registration.

If you join another nationality, you will lose your China nationality.
