"At the present time, the CSC is using two methods to identify expired fingerprints and/or fingerprints that will expire prior to the adjudication of the I-485. On an individual case basis, if the adjudicating officer determines that the fingerprints have expired, she is required to order a fingerprint scheduling request."

We know it is not political correctness to use just "she", they should you "he or she" phrase, but it's government organization and they wrote "she". It means there is only one person who works on adjudication of the I-485

Well that depends, if you take the sentence in context, you could also derive that all adjudicating officers are women!
