I just got my citizenship done last week, and during the oath ceremony the district manager from South Carolina talked to us at leanght. Apparently all cases are processed out of Charleston, and during the renovation of the Charelston office a select few were transferred out to Atlanta, but as of now all is being processed in Charleston. The Greer office etc. only does interviews and such, no actual processing. According to her she had just gotten some staff increases and she was hoping to catch back on the backlog by the end of this year....
Search the posts for a thread posted by me around the 28th of July, it has some more info for you!
