Today, we went to the interview in Garden City, NY. It was a great experience. The officer who interviewed us was a very nice lady in her 40s. She asked us basic questions like date of marriage, how did you meet etc. In the end of the interview she was going to stamp my passport but she realized that my passport has expired (stupid of me, why didnt I extend it). She told me that it may take up to 2 months for me to receive the conditional green card. Can it really take that long? My application still shows as pending in USCIS website. Thanks everyone in this site for their help.
FYI. They did not ask for my wife's birth certificate. The certificate of naturalization was enough.
