Interview Prep advice needed

[Silark 0]

Hi good news we have an interview date but just a few questions.

1. I have read that the documents used to establish my lawful permanent residence status are basically my K-1 visa and also the arrival departure card. Is this all i need to prove that?

2. We need to establish my wife's citizenship in the interview I presumed that this would be done using her passport but this still has her maiden name on. Will this cause a problem?

3. Being the great thinkers they are at immigration they have given me the middle initial of N on my EAD card. I don't have a middle name but they must've taken my N/A in the middle name box on my form to mean my middle initial is N (Everbody laughs at this story so feel free). I have called the helpline they tell me to send it back with and explanation and another EAD application form to have this rectified. Any advice on whether this middle initial is important or should I just invent myself a middle name?

4. Staying on the theme of correct names my name is spelt D'Arcy the problem being the apostrophe. Nobody here seems to have a computer system that can process my name in this way. I had a SS card issued when i worked at a summer camp with the apostrophe but this time around my card was issued without because the lady told me it would crash their system. I was fine with this until i checked my original ss card and it did have a ' in the name. Even my new driving license will not have this apostrophe. All my UK docs have this apostophe in it so will this 'cause any problems also? This does annoy me because I don't want to effectively change my name here.

Ok that's it thanks for your help
