Which USCIS office is processing my AOS?

[stringtheory 2]

We are NYC based and given the directions of where to file our I485, we were directed to file with the Chicago USCIS. I did not realize that there was also a NYC USCIS office until reviewing the processing times just today and now I am confused why we were asked to send our AOS to Chicago when we are in NYC. Either way, how can we know if our case is with the Chicago or NYC office?

NYC is the field office where you interview will be conducted. 

 

Chicago is the processing center

Thank you, so in this case should I be looking at the NYC or the Chicago office processing times to get an estimate of our timeline?

You're looking at 1.5 - 2 years before interview..sit tight and relax..
