Please help: marriage based GC LAChinese2007-04-18 10:35:50

I'm a US citizen. We live in Los Angeles. I filed I-130 and I-485 for my wife. When I asked USCIS office, they said I should mail both to Chicago service center:
US Citizenship and Immogration Services
PO Box 805887
Chacago, IL 60680-4120

I did.

But sombody mentioned Missouri Service Center. Did I mail the forms to wrong service center?

Thanks for your help.
