Good luck with your plans

I heard there's a demand for English teachers so who knows.
Unfortunately, there's no demand in the UK for English teachers right now - in fact because of the recession there are too many qualified English teachers for the number of jobs available - and in order to hire a non-EU English teacher, the school would have to prove that they couldn't find a single qualified English teacher in the whole of the UK or any of the other 26 EU countries (that's out of 500 million people)!
Only pure science (Physics, Biology, Chemistry etc.) and math teachers are in demand here at the moment.
Just a bit scared when I do get there people will obviously know I'm not from there due to my American accent :b Oh well. Aha.
There are quite a few Americans in the UK (about a quarter of a million last time I looked it up) and quite a lot of them are in London, so I wouldn't worry too much about the accent (in fact, in Central London, there seem to be a lot more foreign accents around than English ones

). I have relatives in Arkansas and I feel so out of place with my UK accent, when I visit because there are hardly any English people in Arkansas
