Why did you go to America?

I went to the American embassy for an interview. I was rejected in Guangzhou for the first time and passed in Beijing for the second time.

The basic idea of the answer is: past-present-future.

What did you do before, what is your connection with what you are going to do in the United States, or related experience.

Are you working or are you working now? What's the purpose of going to America? What do you expect?

What to do when you come back from the United States is mainly to let the interviewer know that you will return to China and have no tendency to emigrate.

In short, let the interviewer know that you have a long-term life plan and make sure that you will return to China.
