When Applications filed with a Service Center are transferred to a local USCIS District office it is for the District office to schedule a personal interview of the applicant, usually in order to question the applicant and clarify some issue that was "flagged" or noticed in the applicant's background (a previous arrest, criminal record or a similar name to someone else who is a fugitive, etc., etc.,) or to clarify a possible discrepancy in the applicant's application.
If you feel that none of the above applies to you, them. You could also fall under the 7% or so of nationwide randomly selected cases to be audited and interviewed for "quality purposes."

It appears that USCIS has done one of two things; either transferred an overload of these applications to the local field office for completion of processing, or they want to interview you as a matter of quality control checks. I'd retain counsel if you get called for an interview.
