Sign In Failed (SIF) for IR5

July 15, 2001- The same day NVC received the checklist of response on my parents marriage certificate I also was not able to signed in at the NVC Payment Portal. People on visajourney call it sign in failed or sif. This means that NVC has almost completed it's case and on the process on final review. SIF was exactly 8 business days from the time RFE was delivered to NVC.
