I'm scheduled tomorrow morning and is there anything I should worry about before the interview? I've studied the booklet for about 3-4 months and I'm pretty familiar with it. I've also collected all documents listed on 'Document Check List'. Basically, the letter tells me to bring my Driver's License, my Green Card, Selective Service Registration, expired passport, 2x2 photos, the letter itself and that's about it. Other than those things, am I missing anything here? Thanks.
