To your question from another thread:
This means all case numbers will be following a sequence, e.g. (not actual case numbers, to give idea):
I-130 - XXXXXXX100
I-485 - XXXXXXX101
I-765 - XXXXXXX102
I-131 - XXXXXXX103
This would make tracking easier. Also, if you follow USCIS cases in online trackers, you'll notice USCIS sometimes approves / works actively on some blocks of cases and leaves out the other ones.
I'd prefer for all of them to be reviewed together VS I-130 getting approved first and then crickets or I-485 being stuck because I-130 is not looked at. USCIS used to receive everything for AOS on paper. The times are changing, but you still may get more efficient processing by bundling it together. This is only an opinion. People file both ways.
