I believe we were put in an interview because I submitted my application late. I didn't visit my spouse for 2.5 years this lead them to believe it's a marriage of convinience. Any specific questions that could be asked related to the issue I mentioned?? Otherwise my wife is going to prepare the whole list of questions provided here.I believe you can accompany your wife in for an interview. In the Pakistani Applicants spreadsheet there is a tab on Interview questions. Check out that tab for possible questions. See link below.
If you know why you were put in an interview queue, the good people of the forum can help you with specific questions they might ask. Do you know why they have requested your wife appear in an interview? Any red flags on your file?

I was told that the interview where both husband and wife are questioned is more complex. Is it true?
