My fiance is an American, and we plan to get a license in China, but I don't immigrate. Excuse me, can I go back with him when he returns to America? still

Things are not miscellaneous. Even if you get married, it's between you two. You still need a proper official identity or visa to go to the United States. If you can't go to America, you can follow. What nationality is that? Of course, it is also easy to apply as a spouse. You should be able to get a visa. But the consulate will ask you what you really want. Husband and wife again, don't live together? Think for yourself.
