Interview results and possibility of a denial
My interview was scheduled on 09/21/2012, went into the USCIS office 20 mins before appointment. I waited ~40 min after the appointment time passed and was interviewed by an officer. The officer was polite. I was asked almost all questions on my submitted N-400 and then wrote/read English sentence. After answering 6 civic questions correctly, I was told I passed the interview.
I have known Mr. Khanna and his team for over 15 years now, and have exclusively used their services any time there has been an immigration related need personally or for my organization. They just have a knack for getting things done and I will unequivocally recommend their services to anyone.
