Sorry to be the bearer of bad news Stu, but you will never find any legitimate work in Hong Kong without a degree. Hong Kong is nothing like mainland China. You can not teach there in any school without a degree. The laws there are actually enforced, and the penalties, for both you and the school , if caught, are much more sever. Even if you had a degree, you would likely not be able to find work. Hong Kong is the city that every foreigner want's to live and work in, and the market is flooded like you would not believe with foreigners teaching English. To say it's competitive there would not even begin to describe the situation. If you go there without having work, but hoping to find it, good luck, you won't. Many people travel there, only to end up doing whatever they can to make ends meet. For foreigners this often means they try to pick up tutoring work, thinking it will pay well. Think again. The truth is that the private tutoring market there is also saturated, and you'll be lucky to make 150 "Hong Kong" dollars an hour teaching English there, that's how competitive it is, that's if you can find students.

No, you can't make a go of it teaching in Hong Kong without a degree, no school will hire foreigners without a degree, they have no need as there are so many foreigners, not to mention the stiff penalties. Hong Kong, unlike the mainland, is a city of strict laws, and they are enforced. Even the cops there are "real cops" all carrying wheel guns, they don't just sit around and watch the traffic pass by. You will find, despite the six shooters the cops wear, that it is nothing like the wild wild west, though in many ways mainland China is.

I wish you luck, but I can almost guarantee failure if you try to find work there, and even greater failure if you were to move there without work, hoping to find it on arrival. Even for people who have degrees and years of teaching experience it is quite difficult to find work there. For someone with no degree, near to impossible. Sorry.
