TO answer your questions:
1.) did you do the FP in advance of your scheduled date?
No. I did it according to the scheduled date
2.) what was the scheduled date for 2nd FP?
May 29, 2003 (the notice letter was received at the beginning of May)
3.) Did you get RFE or it was just a clear case?
Clear case.
4.) Has your online msg got updated now with approval info?
yes. That's how I got to learn that I got approved
5.) what is your RD & 1st FP date?
I don't remember the exact date. I only remember 1/18/01 is the date my 1st FP was received by INS.
Some comments: from my experience, I think 2nd FP is NOT automatically generated, instead it's generated by an officer.
