Are immigrants still citizens?

Hello! If you just immigrate to another country, you are still a citizen of China, you still hold a China passport, a citizen of China has a green card of other countries, and you are also a citizen of China. If you immigrate to another country, as long as you don't apply for citizenship of this country, you will always be a citizen of China and still hold a China passport forever! It's just that you don't need a visa to go to the country where you immigrate. If you are a China citizen who has just immigrated or recently immigrated, you have no right to apply for the citizenship of your new immigrant country. So, before you become a citizen of this country, you have been a citizen of China, and your Chinese ID card is still valid! However, when you immigrate to other countries and are allowed to apply for citizenship according to the requirements of the country of immigration, once your application is accepted by your country of immigration, you will become a citizen of your country of immigration and your citizenship in China will be revoked! In order to protect the safety of our overseas Chinese, the China government does not allow our China citizens to have dual international identities. Your Chinese ID card will also be cancelled! I hope you can understand my explanation!
