We just got our interview appointment (Marriage based green card app filed in November) and I will be out of town for a career training that I can't change. I have already booked flights and put a deposit down. All money that would be lost if I canceled. My husband just received his Empl. Auth and Advanced parole combo card earlier this month. Does anyone know if they take those away when re-scheduling? Does anyone have any recent experience with rescheduling in terms of process and length of time before new interview? Thanks for your help! We are in Bay Area, CA
