No clue
I have no clue whether mine was CP or AOS, just can\'t remember, as for the gap between I-140 and I-485, I didn\'t have one because I don\'t have priority date, but I was told by an IIO that they "requested" my I-140 from storage, so I guess they send all the I-140s to storage and request them once it is time to process the case...We all have a gap between I-140 and I-485...of at least a year, more for those who depends on PDs...
