Yes, that's a great question. Definitely, that is a problem, because the officer is tasked with figuring out the genuineness of the relationship, but all these relationships are happening in all sorts of different cultures of which the officer likely doesn't have a real understanding.
A lot of the types of questions that are asked are very intrusive, and a lot of women I've spoken to feel very uncomfortable discussing with a male officer sexual questions about their relationship. That is just one example, but there are all sorts of examples of the problems, and sometimes there isn't corresponding thoughtfulness about how much weight should be given to the answers that are given in these types of interviews when looking at the application overall.
