JK .... NVC seems to be sending the Cases to the consulates once a week ...
the last time it sent was 5/1 .... my guess is as urs was reviewed on 5/1, probably urs should have been sent the same day ....
but for us it was reviewed on 5/2, so it should have been sent yesterday 5/8 ... we will be checking today with NVC for the same today .... U should also check today ..
