My issue is not poor quality photos; it is significantly outdated photos that are being reused despite the subject being virtually unrecognizable. My daughters do not resemble the photos that CBP took 10 years ago and have continued to re-issue.
I did try to call the CBP line and got an answering machine that did not allow the option of speaking to a live human, but redirected me to various websites, none of which could answer the question. I will try to ask in person next time I am at the airport.
