No, I made no assumptions. 😄 I had just never heard of a consideration stamp but I guess they make sense with employment or marriage visas. We just have to show proof of our residence with photos of the villa and us in front, that sort of thing.
No, what would be "under consideration"? They review everything during the interview and if it is all okay it is approved. In 12 years we've never had a "under consideration" stamp.
