My wife and I had every paper we could think of.. Photos, conversations .. you name it we had it.. We got the the interview window... He asked us a total of 6 questions between the 2 of us... He didn't even ask to see anything at all.. Then he simply stated "Your application is accepted" Yessss!!! Basically if you read your appointment email carefully it will state what you really need to bring.. We brought all the extras but we really didn't need them.. I guess better safe than sorry is a good idea.
