I am filing for AP while my AOS is pending right now in CSC. In the Instructions it says if you filed for AOS at a Service Center, then send the AP application to that Service Center.

Well, I initially sent my AOS application to Chicago, does that mean I send the AP documents to Chicago as well even my case got transfered to CSC??

Then in Part 7 they are asking to explain on a separate sheet of paper how you qualify for an AP and waht circumstances warrant issuance of AP.
Is that really neccessary or is it enough to attach the supporting documents?

Thanks for the help, I'd really appreciate some replies. Sorry if this got asked before again, but tonight I don't have the nerve and the brain anymore to do any research.

Anyone to my rescue please?
