Thank you Tod. I'm working through HR at the new school for my communication with Bangkok Immigration. She has already gone the extra mile for me and made several calls to both Roi Et and Bangkok Immigration. New job, new colleagues. At this point I think I will just eat the costs and follow the path that the school believes is correct based on their efforts.
Bangkok Immigration will not process another Non-B extension coming after an extension to visit Thai wife. They will process only from Tourist Visa . So there it is. I will go to Laos and apply for a new Non-B.
I would like to thank you all for your kind support and knowledgeable answers. It is greatly appreciated!!
I spoke with HR at my new school this morning. HR at my new school will check with Bangkok Immigration to determine whether this process is acceptable. I will post the results when I know, for the purposes of informing others,
Thank you for the advice. I will be present with the HR at immigration and labor office for the cancellation process. Luckily in Roi Et the Labor office and Immigration are about 50 meters apart.
