Following our F4 visa interview, our application was denied. We subsequently submitted a waiver request and, after a month, received an embassy request for our passports. Nine months have passed with minimal updates via the CEAC portal. Yesterday, we received notification from the embassy requiring a new medical examination due to expiration. The healthcare provider requires our original passports, which are currently held by the embassy. How should we proceed, and is the request for a new medical examination a positive indicator or standard procedure?
