Hi, I just received the email for NVC with my case#VAC***************

"Dear Sir or Madam,

Your inquiry has been received at the NVC. The non-immigrant visa petition you mentioned in your letter has already been entered into our computer system and assigned the case number listed in the subject line.

As part of the aftermath of the events of September 11, 2001, there are additional security check requirements for visa applicants. While it is not possible to predict when the clearances for this case will be finished by all involved Washington agencies, please be assured that as soon as the results are received, the case file will be forwarded to the appropriate Consulate General.

Regards,

National Visa Center

Now, I have some questions about it.

1) How long do they "finished by all involved Washingto agencies"?

2) If I want to email them again, whick case number should I provide? the USCIS one or this new NVC one?

3) Is it VSC stand for Vancouver, Canada?

4) My fiancée is Chiese citizen, she is studying in Canada from 2003 to present. She also studied in Singapore from 98-00, so, how many police reports she need to prepare? Does she need the Singapore one? If she does, it is difficult to go back Singapore to get it, anyone can tell how to obtain it from Canada?
