Hi everyone again. I appreciate each and everyone's help and patience - by midnights I'm becoming very anxious about the process.
So, my package is finally ready to go, but I'm still waiting for the DV fee receipt ($330). It's been cashed out on Monday but no movement since then. Looking at members' statuses, it looks like it might take 2-4 weeks to receive the receipt (sometimes longer). On the other hand, my estimate (from other's timelines again) is that it takes about 4 months for the case to be processed once the package is received.
Here go questions:
1. Main question - please explain/link to me once and for all, how does the system work on the backend. I understand that it's generally a race against time yet patience is appreciated. But I can't wrap my head around cut-off numbers and internal queuing. Does a case number within the cut-off range mean that a visa is "immediately available" and is sort of reserved (assuming prerequisites are met)? Or are visas distributed on a first-come, first-serve basis within the cut-off range (again, assuming prerequisites are met)?
2. In April a much higher number of cases became current - does that mean DVs are prioritized and will be processed faster (implying faster turnarounds)?
3. At this point I'm ready to give up on the chance for my interview to be waived, if speed is king (see #1). Other than the interview waiver and the (slight?) possibility of the packet being returned, are there any additional concerns about sending the package without the receipt? FWIW, I have a photo of the endorsed money order and a screenshot of the page that says it's been cashed.
Again, thank y'all for your understanding - I literally lost my sleep over this.
