Why do I have to cancel my account when I have a green card?

1. China citizens who have obtained permanent residency abroad, that is, green cards, do not need to cancel their China hukou, nor can they cancel it, because they are still China citizens and still hold China passports.

Only those who emigrate overseas should cancel their accounts, that is, cancel their accounts. According to the provisions of Article 9 of the Nationality Law of the People's Republic of China, China citizens who have settled overseas who voluntarily join or acquire foreign nationality will automatically lose their China nationality. Therefore, the parties should go to the public security organ where the account is located to cancel the account.
