My girlfriend will go to the United States or Europe after her PhD this year. I plan to accompany her. How should I go? Thanks!

...If it is the United States, you may be out of luck. It is very difficult to apply for a visa in the United States, and because of your age, the U.S. Embassy will think that your immigration tendency is very serious, and you have no legitimacy. The reason is that you can't go there. Europe is easier to say. If you want to travel, go there first, and then apply for a visa extension at the Chinese Embassy.... But do you think it's a good deal? Are you going to be a chaperone? What are you doing in a foreign country? Have you considered it? Is it worth taking risks for a woman?
