My wife and I had our AOS interview today at WPB. Our appointment was at 7:15 and we were called on the dot. Our IO was a super nice middle aged gentleman. He asked us for our ID (passport and DL for my wife and for my DL). He then asked for our interview notice. He went on to confirm the information written in the application. This took about 15 minutes. He took fingerprints and a photo of my wife. After this he asked us for documents about our marriage. We had a ton of stuff, from utility bills to a mortgage for a house to car insurance and medical insurance. He talked about his life for a little and his wife. We talked a little about us. After that he said ok so you should receive your card in 1-4 weeks and you'll receive a letter in the mail in a few days. He said we came very well prepared. We spent two days going through stuff to make sure we had everything. So be well organized, be real and you won't have problems.
