Immigration Site

In "Q22 complete the information below if your relative is in the united states and will apply for adjustment of status". Should I just search the USCIS site to find the field office cloest to my zip code and put the city there? Thanks!

Yes.

I thought the answer to this is where you will mail the package to, so I answered Chicago, IL.

How about, in the same Question, if also asked "If your relative is not eligible for adjustment of status....", do I have to answer by putting my home towns American consular post? Thanks a lot!
