Talking of Aug 2003 filings, I checked immigrationwatch.com to see what it predicts for my case, and here are the results:
I485--Adjustment of Status (Nebraska Service Center), lin032485****
Based on the processing record of the same type of cases in this center, statistics analysis shows:
Percent of cases filed around your case's filing date which have been approved: 0.54%
On average(50-50), your case may be approved around: 10/31/06
If you are lucky(75-25), your case may be approved around: 03/31/05
Average approval prediction is for 10/31/06.....SCARY !!!!!
