Today we received communication from NVC that they rejected my husband police certificate. I see that everything else was accepted, and it seems to be an error on NVC side. They rejected it saying that the police certificate was expired, and that is not the case. The police certificate clearly states it is valid for 3 months for submission and we submitted before the 3-month expiration. We have resubmitted with a written explanation, and hopefully they will get back to us quickly. Does anyone know how long it takes for a response after getting a RFI?
