My fiancee has now gotten to the point where she will have medical and interview scheduled. But the medical needs to be done first, and she was instructed to schedule an appointment with one of the approved medical centers.
But there was an issue that she must provide a TKY number, presumably from the confirmation receipt. But the TKY number are for immigration visa applicants, which is not what the K-1 lies under. She has a confirmation code starting with the letter "A" and a corresponding barcode. She clarified that she is on a K-1 visa application, which is a non-immigrant visa, but they insist that she provide a TKY number to schedule an appointment.
We are now unsure on how to proceed.
