Yes, they did, but I didn't really understand. It had something to do with not having a document they wanted at the time but it wasn't listed on their website as a required document that I had prepared for my application. It seemed rather shady. I simply returned to Thailand on a tourist visa and applied again from another embassy and had no problem.
Tod, you have done a stand up job helping so many people on this site. Your many contributions are much appreciated. Thank you! -now I’ll have to Google who the Thai visa centre is…
