緊急求助：EB2 485 was transferred for Interview

EB2 485, RD: 8/14, FP: 9/14, filed to TSC.
No LUD since FP date.

Today just got email as follows:

Application Type: I485 , APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS

Current Status: This case has been sent for a standard interview.

On December 11, 2007, we transferred this case to our LINCOLN, NE location to conduct the interview that is a standard part of processing this I485 APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS.


Just wonder if it is normal or USCIS found something wrong with my case?

Thanks
