Immigration Site

I got an email yesterdays mine and my wifes case has been transfered to National Benefit Center.

In March the Case was transfered to Nebraska Center from My orginal filling center , CSC.

So its now CSC->NSC->NBC

Anyone in similar situation? Possible Reasons?

My PD is 07/2001 and 485 filling date is 04/2005. And 485 application is employment based..

-thx
