Unfortunately this whole process has drained our finances pretty good (with more to come from things like the Medicals from what I hear) so 4 sets of plane tickets in Spring and then 4 more to move in Summer isn't really possible and we are trying to minimize the disruption for the kids by moving them in the Summer so they can finish school one place and start again here pretty close to on normal school schedules.
What do you mean by "speed up a bit once the DV visas are all issued"? I shouldn't expect the DQ'ed to Interview timeframe to continue to be about 2 mo (letter) + 2 mo (Intv Dt)?
Your guess is as good as mine on the BC rejection thing. And the message is less than useless ... I mean tell a person WHAT/WHY you think it was invalid for Odin's sake!
I hadn't seen that this forum had info on how to reschedule and that you could do it before your original Interview Date passed, thanks for the tip I will try to find that info.
