Right! My AOS was sort of fast too, and weird... Read my signature and you'll see. But the thing is, our interview for AOS would have been in Pittsburgh, PA, which has one of the highest approval rates and actually the officer that called me was very, very friendly and nice. We moved to Columbus, so I am not really sure if Columbus is fast or not.
There is another person here in VJ that is going through Columbus, and his wife got the interview in four months. And another one in three weeks. But my issue is, I don't even have the biometrics, so my application is still at NBC and it will be there until someone finally decides to look at it.
