I've noticed a bunch of new I-140 cases in the most recent IOE09332 and IOE09333 blocks but they're all/mostly dated as received in the past day or two.
I have a non-premium I-140 that was delivered on August 1. Is it normal not to have yet received an electronic receipt notice despite seeing cases newer than me already being assigned case numbers? I'm assuming most or all of these new I-140 cases I'm seeing are premium?
