Topic: Visa Bulletin conundrum

Hey everyone, My PD is 5th july 2001 from F4 category, and from what it seems, my PD may get current this upcoming september visa bulletin. I and my family have already been interviewed with the exception of 1 brother. Then retrogression took place so we were put on hold. Now in June Embassy 'accidently' told us to give new DS230 forms and med reports but after a week, were told to wait until our date gets current. Now that since PD date may get current, what do you guys think will they tell us? We have already conducted our medical before getting their email so We'll be submitting the same med reports but How many days do you all think they'll take to contact us again after our date gets current?
