Greetings sir, as an international prospective student proposing to study at postgraduate level in Thailand. I would appreciate a record time detailed information and guide lines weather it's possible for someone having obtained a master degree from his/ her home country to get a work permit in Thailand. Although, reason for traveling to Thailand is to study but at least it would be prefered and appreciates if one can get a job in order to ease all expenses. 

If you find a job here you can get a work permit,  a non immigrant b visa and later an extension of stay based upon working.

You can attend school with any type of visa entry. You cannot work on a visa issued for education purposes unless it is a internship arranged by a university.

Check the benefits from your homecountry if there is enough to take care all expences.
For example from my country (FInland) you can get benefits for living and housing even if you study in foreign country like Thailand.
