Strange, give a proof or are you just spreading lies? We have been recruiting teachers since
2007 and I do not have one single case where the Hong Kong visa run did not work…

Go ahead and get the Z visa before coming to China if you want, it doesn't matter. We're just
giving you more options.

Again, thank you for your honesty. Breaking the law is always an option.
Anyone who is interested in accepting a teaching position in China through Golden Staffing should be aware that for 8 years they have been bringing foreign teacher candidates illegally into China on tourist visas then sending them to Hong Kong in an attempt to acquire legal Z visas.
If that is the kind of organization that you choose to fly half-way around the world to work with, you deserve whatever happens to you.
