You are right, we got her police clearence certificate from the Embassy but there were no records available for the deportation. I cant predict what may happen at the embassy, but i can say in our experience that we twisted ourselves in knots about this issue prior to the interview and the embassy didn't ask about it. The questions were only related to how much time we spent together, when was the last time i visited Thailand, etc. We used a professional to prepare our documents and evidence, and like many others on this forum had mentioned, a well prepared visa application with lots of evidence made the interview process a breeze.
