Just an FYI for anyone interested.... I was fairly certain that my GGF had never been naturlized and that there was no documentation to the contrary.
I had never requested a record-search from USCIS (only from the National Archives), but I just decided to go ahead and request a certification of no-record from USCIS. I wrote off asking for the certification and received it back in exactly 1 month.
That seemed like warp speed compared to some of the other posts I've read, so I wanted to post a positive report, as well as bring up the possible strategy of writing them even before requesting a full record-search if you're pretty confident that your ancestor had no naturalization records.

I did the same thing - skipped the index search and went straight for the nonexistence of record. Took 45 days and, unlike the index search, it was free.

hiGHFIVE!
Yeah, it definitely felt good to get that out of the way and I highly recommend it.
