Think about this. there are few people got their application approved in a month. So all the circus what they do would have been completed in a month itself. Having said this, i am sure this background and security could be completed in couple of days provided someone is working on these
.
In my case i never heard my back ground or security completed but directly that it has been approved (no slice and dice).
End of the day, these all are theory. So anything could happen. Stay brave and keep waiting even though it sucks, but there is no other option.
So stay positive...we all will get through.
