I just submitted a request for a No Records letter from NARA. I'm assuming they won't find anything since I already have a CONE and records from USCIS Genealogy stating that they have no naturalization records. Has anyone submitted to NARA recently and can tell me how long they actually took?
Also, since I asked for a certified copy on paper, will I get results sooner in email or do I just have to wait for the paper to know if they found anything? Thanks!

As of about 10 min ago I saw appointments for June 9 and October 20. Maybe more but I can't see them anymore since I booked one for August!
