Immigrants forget about China.

No, immigration and naturalization are very different in real identity. Immigration does not mean naturalization. For example, immigrants to the United States only have the right to freely enter and leave the United States and the right to live in the United States for a long time, but they do not enjoy the political rights of voting and being elected, because they still hold China passports, and only overseas Chinese, that is, people living in the United States, hold permanent residence cards, also known as green cards. Naturalization means becoming an American citizen, having the right to vote and stand for election, and holding an American passport. Of course, there is not much difference between the two in terms of economic treatment.
