1. You can find a job if you get a green card. You'd better know about American living habits first. In many places, the habits of Americans and China people are completely different, so if you do public relations activities in the United States, you can't use all the experience of China.

2. If you apply for other visas while waiting for your green card, such as visa F 1, then the Immigration Bureau will doubt your motivation to go to the United States. I suggest you sign up for some language courses in China now and practice your language to go to the United States.

It is easy for local Americans to find jobs, because many enterprises only recruit Americans. It is still very difficult to become a white-collar worker after graduating from community college.
