It looks like it has something to do with my company's expat-Thai ratio at the moment. Maybe it's not just getting Non-B back to back and just getting extension for three months, I'm not sure, not really familiar with any visa procedures.
Thank you very much. It might sound like a dumb question but normally I would get my visa at Chaeng Wattana, I better go there to get this information or can I find my answers at Pattaya immigration as well?
