HELP26 This is what I think happend
When you guys go for your fingerprint, the Technician at the Application Service Center does your FPs, then a QA Person determines the quality of the finger prints. If he is satisfied or your FPs meet the required criteria for quality, then he/she Oks the FPs and they are sent to FBI. Now, the messy part, it all depends on the QA person whether he was carefull enough to OK those prints are not. If by mistake he accepts FPs that not of good quality and they are sent to FBI, FBI will not report the problem to ASC. They only communicate with INS. When INS looks the FBI report( which in your husbands case there is no report since the Quality of FPs is not good ), they request you to submit FPs again. I know it is a pain , but unfortunately INS looked at your husband\'s print only recently , otherwise you guys would have come to know about that earlier. Thats why I again say that follow-up is required if you want your GC without unnecessary delays. I know some people on this board, who dont believe in this, but please do not take things for granted. It does not hurt to follo-up the status. Anyway this time, you guys can make sure ( talking to the QA person tell him/her what had happened) FP quality is good.
Goodluck and All the best in GC process
