I don't understand your question.Hi Scylla,
Sorry I’m disturbing you once again, I was wondering since they have flagged my application as a non routine case, Do you think even after getting pre-arrival services letter they will treat my application as a non routine case and will do the background checks at the same pace.
Waiting for your valuable response !!
Background checks vary in how long they take depending on a number of factors. It's very individual and hard to guess how long this step will take for you.
