Thank you for the question.
Basically, the reason I say that we should tape or record these interviews is that I'm in the process myself. My husband went through the interview. What he told me happened and what the agent wrote in the GCMS note were completely different.
It's not the first time I've heard this. As a spousal sponsorship advocate and administrator, I'm also a therapist during those times, because I hear the same thing over and over again. They always say, “I said this, but it's not in the notes.” Recording these interviews would hold the visa officer more accountable. If this person had implicit or explicit bias, they would not have any space to project their own bias onto the person they're interviewing.
I think it's very important. It should be mandatory to record all of them.
