How can I obtain a Non-B visa in Thailand using my diploma?

We've got a difference in Englishes here. In the U.S. a diploma is a piece of paper you get finish a school -- high school, college/university, masters, doctorate, etc.

That said, the qualifications required for a job are really different from place to place in Thailand. In Bangkok you have to be Good -- very Good -- lucky or connected. Many foreigners want to be in our around Bangkok so competition is fierce. A project manager-engineer friend is teaching English in a small place in northern Thailand and he's by far the best one there. He says half the other "teachers" are not teachers and some can't speak English. They just have a foreign face.

I suggest that you look for work as a cyber security spook in outlying cities, learn to enjoy Thai provincial life for a few years, get a name as being Good, reliable and honest, then move into a job in a tougher market. I'd say it would take 3 to 5 years to build a good reputation unless you're absolutely brilliant.

Masters degree in Teaching English to Speakers of Other Languages. Should have been a breeze but was a real nightmare with having to take them to the U.S. Embassy to get them certified but they only would have me sign an affidavit attesting that I had graduated on dates indicated. Fortunately the Ministry of Foreign Affairs accepted that and have me the necessary stamp. My colleagues are whatever majors with little or no experience but just breezed right on through.
