Fastest I-485 in the country??

[earthlovers123]

Any body know which is the fastest I-485 processing DO in the country ?
My understanding is you have to apply to Chicago Office and it will be transferred to Local District office .
It seems like Buffalo NY is the fastest I-485 processing centre .
Do you send I-485 , I-130 , Medical , Affidavidit of support all together to Chicago Lock box in one application ?
Any body know which is the fastest District office which process the case GC for Parents of USC Daughter/son?

Dallas seems to be very fast too. Some of my friends have had their relatives' 485 approvals done in a month or two!!
I would suggest you to look up the relatives gc forums at http://boards.immigrationportal.com/forumdisplay.php?f=39 for experiences/opinions on the kind of information you are looking for.
