yes, but an estimate on what is next is appreciate, (i am in Dominican Republic)
after i submit the AOS and IV Form i receive a notification that now i have to wait for the interview, how long is that wait, 5 months, 5 years...? my priority date is Nov 2015, and the current one is 22 Sept 2015, how long USUALLY (usually guys, i am not asking for scientific exact dates).
Those process, the order is almost the same, times vary a little (similar cases) so is not that space science difficult answer required. For someone who already has gone thru this process or know about it usually knows what thing follow the other thing...
