What's the difference between immigration and naturalization?

Immigration includes two different ways: holding a green card and naturalization. To talk about their connection, most countries must first hold a green card and stay in their own territory for a certain period of time before applying for naturalization.

Obtaining permanent residency (green card) is only the right to be allowed to enter and leave the country at any time. The holder's nationality has not changed, and he is still a citizen of China, just living abroad, or his identity has become an overseas Chinese (China nationality). If he immigrates to America, he is an overseas Chinese living in America.

There is little difference in economic treatment between obtaining permanent residency in an immigrant country and joining the nationality of an immigrant country, but there are differences in political treatment (citizenship), mainly reflected in the protection of laws in different countries and the obligations of citizens in different countries.

Naturalization explains the nationality of the immigrant country and becomes a citizen of the immigrant country. For the original country of residence (home country), it is a veritable foreigner at this time. China's laws do not allow dual citizenship, so our citizens automatically lose their China citizenship after joining other countries' citizenship, and they are Chinese Americans.

2. Different political treatment.

There is little difference in economic treatment between obtaining permanent residency in an immigrant country and joining the nationality of an immigrant country, but there are differences in political treatment (citizenship), mainly reflected in the protection of laws in different countries and the obligations of citizens in different countries.

For example, a citizen of China holds an American green card, and he is also protected by the laws of China in the United States. However, whether he is in the United States or returns to China after becoming an American citizen, he is protected by American law.
