Mr Wang’s name gets around a lot. I actually saw him this afternoon. I’m not sure if it was his info that Ryan sent you via PM but he’ll be able to at least point you in the right direction if he can’t help you out personally. In the few minutes that I saw him today he received two phone calls from foreigners regarding visas.
I might be mistaken but I don’t think not having a degree will be an insurmountable obstacle for you. Through getting visas for the last few years I don’t think I’ve ever been asked for a diploma. The school you’re employed by might have that as a requirement but strictly speaking I don’t think it’s 100% required to process your visa.
Good luck!
