I really want to know the concept of immigration. My boyfriend emigrated, can he come back and marry me? Can you find a job and settle down in China? What difficulties will there be?

Immigration means that he has lived in a foreign country and has legal residence status. Besides, he is no different from other people in China. Of course, he can choose to live in China, because he is still a citizen of China (unless he is naturalized in the host country later). When you reach the legal age for marriage, you can get married. How long was that? Only you know.

The other one; Don't talk nonsense if you don't understand upstairs. Who said that marriage between a foreign passport holder and a China citizen is not restricted by the China Marriage Law?
