We had a second visit from immigration, this time from the office in Sadao. This I was told had nothing to do with my extension, which I collected a couple weeks before, rather their task is to check on the validity of marriages - checking for fake marriages. All very polite, a few photographs, some questions, sign a document saying we're married witnessed by someone not from the same household or family. No idea if this is to be a regular thing or not.
