My question about the niece photo was more on the lines of: "If you saw a picture of a man and a woman who are in love, and a little girl who looks like the man and is the right age to be his daughter, at first glance, who would you guess the little girl was?" Even if the interviewer believes me consciously when I say it's a niece, I don't want to put any type of subconscious doubts in his or her mind, which might affect his or her attitude toward me.
Oh, I am relaxed, actually, even though I might not have given that impression here. I'm 39 years old, been working since I was 17, so I've been on lots of interviews; I know how to handle myself.
I've pretty much got everything prepared, based on what the Britainusa website asks for. I've even got a looseleaf binder already set up with separate compartments for each bit of info so I can make sure I'm not missing anything. And an extra folder that I will carry with me but not give to the interviewer, with stuff I will show "just in case" the interviewer needs more-- phone bills, letters, etc. So I am not burdening the interviewer with extraneous info, but I don't have to reschedule the whole interview in case the interviewer needs more info. I don't want to give too much paperwork, as I work with contracts and I know how annoying and unproductive that can be. So I will appear quite organized, and of course I will be wearing a suit, etc.--like someone who would be quite capable of getting a job and supporting herself in the UK.
