Bear in mind also, working in Thailand without a degree, or worse, a fake degree, is highly illegal. At best, you will be held in a Thai immigration detention centre for a few days, and then get deported. At worst, you will be in there for several months ( some foreigners have been ) and then you will be deported.

I have been to a Thai immigration detention centre, and believe me, it is not a place you want to be for any length of time.
Unlike China, where nobody cares if you have a degree or not, or a fake one, in Thailand they do take it seriously, and they do check.
