My wife has her interview scheduled for September 13, which means her 6 month window to enter the USA will expire a few days before our 2nd anniversary, assuming that 6 month window starts from the interview date. Does anyone know if that’s the case or is there a delay in processing a passport as it typically takes awhile to receive it back after the interview from what I’ve read? It is possible to reschedule the interview with cause, but does anybody know how feasible that option is?
