The purpose of the marriage-based Green Card Interview is to prove that the applicant entered the marriage in good faith and not for immigration benefits. The interview questions may be grouped into several categories:
Questions about the beginning of your relationship (how you met, when the relationship became romantic, where and when the proposal took place and more)
Questions about your wedding (date and place of the wedding, number of guests, honeymoon location and more)
Questions about your relationship and life together (number of rooms in your home, whether you have a joint bank account, what bank you use, type of furniture in your home, etc.)
Questions about your spouse (education, favorite meal, work schedule, mutual friends and more)
Questions about your joint financial relationship between you and your spouse
