John, you make a lot of assumptions. This school has a notorious reputation in Guandong. We should thank the original posters for their information. And by the way you are absolutely incorrect about the guest lecture tatus for F visa. I'm a professor and I've been invited by several local governments on many occassions on a F visa and have been well compensated for my lecturing.

As far as everything else you wrote, you make a lot of long-winded off topic assumptions. People like you do not add quality to these boards but more noise that newbies have to sift through.
