Hi . Yes you are right. It is complicated. What I did was, I uploaded the paper that the Police has given me which basically a receipt that you have applied for a Police clearance and that it is being sent directly to the US Embassy in 7 days. But then it took awhile for me to get an interview after I was DQed, so what I did was I went to get another police clearance 3 weeks before my interview just not to have some loose ends that will delay the issuance of my visa. It all went well. I got my visa right after the interview. It was issued right away but I only got my passport back 5 days after.
