In early February, we received notice of an I-130 approval around the same time we received an Initial RFE tied to the I-485 that was asking for the medical exam. We sent the medical exam overnight mail the same day we got the RFE (tracking through USPS showed it arrived at intended destination). This was two months ago. When looking at the status of the I-485, there is no indication that they received the medical exam. It just says that they sent that same February RFE and we have until a specific date in April to reply.
What should we do, if anything, at this point? Does it seem like perhaps they lost it? I am not sure who to call to check on it or if just waiting is all that's required of us at this point. Thank you for any insight you might have!
