I went briefly through your previous posts. I saw that you said you saw DM on your wife's side, so that would be sponsor (SA). I haven't seen that you received AIP. If that's the case (no AIP yet) and your file is transferred to your local office, it is usually because they have doubts about something and they might call you in an interview. If that's actually the case, you shouldn't worry too much neither. They will give you the opportunity to address their concerns.Mine went from Mississauga to Vancouver and I called today and it is in Edmonton, where I live, I don't know if that's a good or bad sign.
My guess (if SA, no AIP, and transferred to your local office) is they might have doubts about your relationship. If you're indeed called for a relationship interview, just be honest. People in a genuine relationship shouldn't be afraid of this interview. They might ask very personal questions like how often do you have sex.... and some lighter questions like which side of the bed do you sleep, what is the colour of the curtains,...
If you have SA and AIP already and not DM, but transferred to your local office. That could simply be a quality assessment interview. Much lighter!
If you see DM on both sides on ECAS and your file is transferred to your local office, then you're done. You're waiting for the landing interview.
In any cases, I wish you the best and as soon as possible!
