Hi,
I meant USCIS National Customer Service Center (800) 375-5283. There are some categories that are subject of expedition including DV Lottery. By calling National customer service you can ask for and expedition. this will speed up transferring of you file from the National Center to you USCIS focal office. NBC is national benefit center which its contact is same as national costumer service.
