We're special.
We got AIP twice, two months apart. The first AIP, one month before the spousal interview, the second AIP, 30 minutes after the interview. The content of the letters sightly differ. The interview itself was simple: went through the list of documents we were asked to bring in, and then separating us for 5 minutes to ask what are typical landing questions (i.e. prior criminal record, date of last entry, kids, etc) to confirm accuracy. We did not land though. There were no personal questions asked. At the end, we were told to wait 1-2 months for letter regarding the decision of the interview.
Not sure what to make of all this, just more waiting, I suppose.
