GCchaahiye,
I checked my I-485 reciept notice once again. Its written 160-180 days. But, are you supposed to take this seriously. Its already 120 days since I got that reciept and I still have not got any FP notice. I dont know if they differentiate if you are EB-1 or EB-2 or EB-3 at I-485 stage. No matter what you category is it all depends on your reciept date I guess. I maybe wrong. Anyway here are my I-140 details.
Applied myself under NIW category (RD Jan 25, 2002, which said taking between 30-60 days) got an RFE in July (they asked for more testimonial letters from people I didnt know and who work at National Institutes like NIH, NCI, CDC etc explaining that my work is in National Interest). Got letters and replied the RFE myslef a week before the deadline (Oct 12) and got my I-140 approval on Nov11, 2002. Had to wait for some months to get my Birth Certificate from India and filed I-485 in May (ND 05/16/03, RD 5/18/03). Since then no word from BCIS.
By the way in one of the chat transcripts (murthy.com) somebody was curious about the time frame for AP (advance Parole). Normally one gets it in 90 days but he had a reciept stating that its taking 300-400 days. She replied back saying that the clerk might have pressed the wrong button. I hope it holds true for penpen's case too (900-999 days)
