you have nothing to lose in trying ( apart from a few hundred quid on a tefl), consider doing a tefl and come to HK and try at most 6 months later you can go back to uk, also what will ur missus do after 24 months on a youth mobility scheme? will you marry then?
there many benefits in HK, lower taxes is one them, you will pay around 50-70% less income taxes compared to uk.
I'm here in hk at the moment but yeah we will only go to the uk if we have to. Looking to marry maybe next year or 2 years max either back home or get the family over here or sth I don't mind. Staying here rent free too so would only be looking to earn anything over 10000 a month just to get a foot in. One interview tomorrow for a learning centre so see how that plays out.
