NVC just received our case from USCIS. My spouse is currently in the US on a 90-day tourist visa, and we forgot to get her police certificate before coming. I understand we need this to submit our documents to NVC, and it takes 2-3 months from the embassy here, but only a week or two in Japan. So, we plan to wait until she returns to Japan to get it, which will delay our NVC review by about a month. Is this correct? Can we proceed without the police certificate, or is there any way to get it faster while in the US?
