My boyfriend just immigrated to America. How long will it take to get a green card and how to apply for going abroad?

First of all, the man must be a citizen. It is very difficult for a man to apply for a green card, and it is absolutely impossible if he is just visiting relatives.

On the premise that the man is a citizen, he can get a fiancee visa, which is faster.

Or, let him come back and marry you, but in this case, the man's return to China will affect his identity and may lose his identity.

Why don't you wait until the man becomes an American citizen before applying for a fiancee visa?

It takes five years from getting a green card to applying for citizenship, so it may take several years.
