Thank you Pete for your prompt reply!
I do consider myself as bilingual, my other language is french so I doubt it could be useful in Asia.
I plan to get some TEFL training, it would help me gain confidence. I'm less impressed by the exoticness of Asia compared to the excitement of a career change.
As for the degree, I realise it might be worth getting one, has anybody tried getting one through anything similar to the "open university"?
If yes, how long did it take you? between 3 and 6 years? did it cost you much?
I would be interested in finding out alternatives to the "open university" as the fees triple if you do not live in the UK (I really don't understand why as it's all done by mail or online).
If I understand well one can quickly get burnt out teaching without a degree and therefore no valid work visa or descent salary.
