sorry I have no idea how long it takes in Nicaragua.. but for me it took a week after the NVC sent it.. so I think you should email the embassy with your name and ur fiances and ur CRS number and ask if they have received ur case.. thats how I did it
!!! ON ITS WAY TO THE U.S EMBASSY IN NICARAGUA OH MAN !!! WOOJJOOOOO
I did email them though thanks!!
I'm possitive it will go fast for you.. I know after it leaves the NVC everything gets faster so I know ur interview will be scheduled soon
