Good day everyone, my wife just received her interview letter for her n400 application which we filed for on our 3 yr anniversary(march 2022) at the san diego field office. We already applied for i751(march 2021) before, but as of today, it's still showing "case ready to be scheduled for interview". Will this be a combo interview? Would like any response and also if there's anyone here familiar with the san diego field office. Do they do name change and oath ceremony the same day as interview? thanks a lot.
