It occurs to me ,Foxy, because you can get L visas in-situ whenever you need to renew, why would you need an employer anyway? Why don't you go freelance and build up your own one2one adult students? You have a Chinese wife to put advertisements on free Internet sites(many of them) and there's also recommendations. Even safer to boot, because you don't have to worry about the police doing random checks on schools. Lots of little businessmen in China who need to learn some English but do not have the time to attend English Centres. It can't be done without effort of course. If you get too busy you could even employ San Mig, or me, or...... You could also branch into Internet lessons over QQ. Have you given this any thought?
