Hi you two, and everybody! I would suggest you just have a look at the job offers posted on several tefl sites such as tefl.com. It states there exactly what they look for and that ranges from CELTA qualified natives to people who simply have a degree in nothing relevant to ESL, but an obvious close connection to an English speaking country. As for me (not an English native), I have found a job as an English teacher in Beijing having a degree in Communication and Film Studies and a 3 month teaching experience, which is not much at all. I'm sure you'll be fine finding a job in Thailand. About Greece I have no idea, sorry. ANyway, GOOD LUCK!!
