Of course! In their official letter , they stated " we have SENT" ... Please allow 30 days to NVC receive it... Sorry to say this but as much as we not saying anything and do nothing and just wait , they keep delaying process. Unfortunately regular USCIS operator have no knowledge and they just reading and responding from the transcript. Call USCIS ask for tier 2 agent, yes it will take up to 30 days to call you back but it worth.
