I went through the K1 process and filed to remove my conditions, I knew I would have to do it anyway but I think I was told a few times, and anyway it is a negative part of the K1 process and well covered here. Back when I did mine at least it was quick.

Now they tend to reuse Biometrics but I think I had to go back and have a photo done? I forget. Anyway this is more a question as I do not know the answer, I am sort of assuming you can get the extension and if you need to do Biometrics that can be done when she gets back.
