> I knew a Chinese exchange student who would debate all sorts of things, but when you brought up the Chinese government she would come to a hard stop and say "I don't talk about that."

If she's considering immigrating to the United States at any point in the future, she would be wise to not debate anything that has to do with the United States, in any electronically recorded medium.

All visa/status adjustment applicants now have to turn over their social media identities. It would be prudent for her to not express a viewpoint[1] that might have an adverse impact on her immigration.

[1] What are those viewpoints? We don't know - CBP won't tell anyone. And whatever they will tell, may very well change in the future.
