My boyfriend immigrated to the United States since he was a child and is about to graduate. He wants to invite me to his graduation ceremony! What do I need to prepare for my visa?

You should be a student, right? If you are a student, I think it's better to tell the truth ~ you don't know what questions the visa officer will ask you then. If your answer makes the visa doubt your relationship, you will certainly fail ~ and the advantage of students is that you have school certificates, and it is generally believed that you will definitely return to China to complete your studies. Note that you should emphasize that you only used your vacation time to go. But if you are at work, it's really hard to say, because your situation, even a friend, is likely to arouse the suspicion of the visa officer, so you can only get away with it ~

In addition, the visa officer will keep asking him what he thinks is in doubt until your answer satisfies him. So if you hide the truth, it's easy to expose yourself. Last time I signed it, the boy in front didn't answer the questions very well and was always asked miserably.
