Should I change my nationality?

Hello, there are two kinds of immigrants, permanent residence (green card) and nationality. You don't need to change your nationality if you just get a green card. But remember, China does not recognize dual citizenship. If you join another country, you will no longer be a citizen of China. You need a visa to return to China.

Another point is that the green card has no right to vote and has the right to vote; Naturalization has the right to be elected.

A green card is a permanent residence permit for foreign citizens.

Naturalization means that a country accepts foreigners or stateless persons as its own nationals through formal procedures on the basis of their voluntary application.

Take Germany as an example. It takes three years to get a German green card and five years to become a German citizen.

I hope it is useful to you, thank you!
