Hey pushbrk, I had few more questions:
I received an email from NVC about my interview in Frankfurt:
I never received physical mail. Would printing this email be enough?
Another thing, on the USTravel Portal, I set up the delivery option, entered all data, but there is only an option to select a new interview date, and it isn't showing the one set up by the NVC:
Is the case for CR1 interviews, because they are set up by NVC, and not through USTravel portal, or did something go wrong?
Thank you again!
