Hello,
I submitted on Jan 7, but my number is high. I think these are all logical stages, but you never know. When I called after almost 4 weeks, I was told that my DS260 is waiting in queue to start processing (picked-up by someone to start processing). I have no idea how fast things move, but it is quite worrying that after 4 weeks, DS260 has not started processing. Based on what I read on the forums, I think both stages 2 and 3 take quite long time. Stage 2 is at least 4 weeks now for me. If your DS260 is processed before 2 months that you become current (when VB updates), then you are going to have the interview on the month that you are current. If not, there are delays in stage 5 - and once you get into delays at the end of the year for visa, it gets quite risky. That is what I think. Till you do not get your stamp in your passport, it is like you do not have it.
My impression is they do say they process in order they receive, but I am not sure 100% about it. I think they split by regions, they process in order they receive by regions. It is not really in the order they receive. And lately they are messaging people that have not submitted DS260 to tell them to submit. To be honest, I do not think this is fair. Because they should spend time processing what they got, not emailing people telling them to apply. But it is a lottery, so I guess anything is possible.
But you are safe, if you get current in May. I am only getting current (if I hopefully do) in July/August. My number is Europe region.
