AOS interview at Chicago DO

Hi!
Yesterday I had my AOS interview at Chicago DO. After reading this forum I was a little nervous and I tried to prepare as much as I could, we had all the requested papers, pictures etc¡K Our interview was scheduled at 8:10am. We came at 7:45, 8:15 the interview started. The officer asked our ID's, then he looked at my file, asked for joint accounts (we gave him papers on condo, mortgage bills, car insurance, health insurance, credit cards on both names), then looked at the file again for about 2-3 minutes, asked a copy of our marriage certificate (he couldn't find it for some reason). After that he told that everything is fine (no other questions!?, I was very surprised), he is going to approve our case but he needs me to take fingerprints again (because it was more than a year after I¡¦ve done them?). And as soon as he receives fingerprints they will send me an approval letter to go and stamp my passport. I asked how long it will take, he told about 2 weeks. I asked him his name just in case. And that was it. Everything was about 10 minutes. Now I¡¦m just hoping that it will really be 2 more weeks.
Good luck to all of you!
