This is a known issue. Sadly, fingerprint approval is a 50:50 chance, especially if one did them on their own (without seeking a professional fingerprinting technician). I am also dreading the day my card gets charged (sometime in Feb 2018) and keeping fingers crossed (#pun) that the fingerprints go through. And I didn't even include multiple copies (can include upto 5 copies per application).
PS: I used UPS to get my ink fingerprints.
Thanks for the response. It's just frustrating.
I put in multiple copies, but I did have to do the prints myself because of my travel situation. I wish I had had more time to get them done professionally.
But good luck to you getting yours approved!
