Here's the detail:
I got there early . My appointment was at 10. Parking spots are tough to find around there. I parked 3 blocks away.
I waited out of the interview room till around 11AM before I was called in. The officer was not rude. She called me in to her office. Asked me to raise my hand and swear to tell the truth, etc ...
Then she asked for my passport, GC, and driver's licence. Then she went through all the questions in the Application and told me to sign on the dotted line. At the end I asked her about traffic tickets. She said traffic tickets should be entered in the application. Then we enterd the traffic tickets in the application and I gave her the letters from courts that the tickets were resolved.
She asked me if I had filed my taxes on time every year and whether I owed anything. She did not ask for copy of Tax returns from me. But someone else was asked to mail a copy of her tax returns to the INS office after the interview, even though the applicant was a wife of a citizen and the tax return was filed as joint.
She asked me about my trips out of country. The test was very easy. 10 multiple-choice questins. All from the 100 sample questions. I could have answered all of them without even reading those sample questions.
At the end she showed me a public notice from Dec 2002 that said "due to security procedures some N400 and I485 applications will go through security checks, sorry for any inconvenience..."
She told me Homeland Security has to check with other agencies before the final approval, then said "let me check if your security check has been cleared". she checked in her computer and said "not yet". She said they set the applications aside and check the security checks every month to see if they are cleared.
She gave me a letter saying "You have passed English and history and civics test but your application cannot be approved now ....." and said they would send me the oath letter when the security check clears.
That's it
