Vista,

You wrote in your posting:" No longer is going to Hong Kong an option, it must be in your native country.( where your passport is issued )"
This new regulation is valid only until 17th. of October, isn`t it ? ( it was one of the changes caused by the Olympics in Beijing ).
I used to come on a tourist-visa to China, to check several schools before getting a work-visa. In my opinion, this way is safer for the foreign teacher.
