Would have to agree with Braniff. With Thai Airways on the ropes, so to speak, and the plethora of low cost outfits in Asia there just don't appear to be any good jobs in Thailand right now. If anything I might target Bangkok Airways. They seem to be well run and have grown slowly, but steadily, over the last 20 years or so.
If it's possible for you to stay in the USA and do some flying after graduating I think it would serve you well over the course of your career. The biggest difference will be CRM and safety concepts, which are far more advanced in the USA than they are in Asia.
