Where do I send my AOS application I-485, etc?

[Jimmy the American 0]

I'm trying to make sense of the instructions of where to send my application! I'm here on a K-1, and need to Adjust my Status!! I have everything ready to send.. but I can't fully establish for certain where to send it. I'm living in Montana. Do I send it to Chicago? Or the local office?

Thanks

Everything goes to the Chicago lockbox, just like it says on the front of the I-485 form.
