TEFL without degree?

[goter]

hi

This is my first post! I'm planning to quit my job and travel. I just haven't decided where to. I'm thinking about TEFL as an option but I don't know if I'm qualified.

Is a degree necessary to teach english overseas? Would a TEFL certificate be enough to get a job?
At the moment I have a college diploma, which is kind of vocational rather than academic. Although I'm capable of university work and this diploma would give me access to the second or third year of a degree course.
I was thinking about taking a TEFL course somewhere in Asia. I'm interested in China.

Any advice would be appreciated? Thanks.
