What is the synonym of immigration?

The synonyms of immigrants are green card, foreign nationality, foreign passport and foreign citizen, all of which are synonyms of immigrants.

Among them, the green card refers to China people who have settled overseas for a long time, but still retain their China nationality, have not joined foreign nationality, and maintain certain ties with China. This word is also the most commonly used to describe immigrants.

Foreign nationality means that China people give up China nationality and join foreign nationality. They have nothing to do with China, so they need to apply for a Chinese visa to return to China.

The meaning of foreign passport is the same as that of foreign nationality, which means that China people who emigrate overseas give up their China nationality, join foreign nationality and obtain foreign passports. The original China passport has been invalidated, and they need to apply for a Chinese visa to return to China.

Foreign citizenship also means that China people who emigrated overseas gave up their China citizenship and became foreign citizens, not China people.
