I am currently in China visiting my wife on an L visa. My wives family found a local school that would like me to teach English for them. When the school went to apply for an invitation letter for me to convert my Visa to a work one, they were told that I would have to go to either South Korea or Hong Kong and then the invitation letter would be sent to the consulate in either of those two countries. My question is has anyone ever heard of something like this before and can I get a work visa if I go to South Korea or Hong Kong?
