Also, my own updates: Received letters in the mail (U.S. address) on March 8 and 9 - one with my report, another with reason stating wife's fingerprints rejection ("the quality of characteristics is too low to be used").
And here comes a twist...
kriscan, my email request to open the early February package worked. My credit card just got charged. Essentially, they expedited our forms. Unbelievable. There are some humans working at the CJIS after all, and may they be blessed.
I had written a simple email (short and to the point) explaining the situation (one set of forms were processed, another got rejected, had sent another package fearing prints rejection) and providing the relevant dates and info (first package delivery date, first package processed date, second package delivery date, sender's name and country, applicant name, DOB, SSN). I then asked if it was possible for them to just get hold of my wife's prints from the latter package and rerun them. Finally, I mentioned this was the only thing holding up my PR application to Canada. Some kind soul at the other end took pity. Asked me if there was a tracking number for the package, which I subsequently provided. And now the credit card's been charged. I am happy and grateful. Whether the fingerprints go through this time is a whole different story, though. The final act (denouement) is yet to be staged.
You should definitely give it a shot as well. I think this won't work for folks who have yet to send a new package but just might work for those who sent in another set of forms/prints way before their first package was opened. I believe you did the same as well. All the best.
