Thanks for the clarification. My experience has been that every time I use the machines, they then retake the fingerprints and retina at the officer anyway. (

Thanks for the clarification. My experience has been that every time I use the machines, they then retake the fingerprints and retina at the officer anyway. (This is possibly because I'm a green card holder.) They also seem to have a wide range in staffing levels, and adjust what is "open" based on that. You are right about the efficiency. Quite simply none of the people involved at that level have any incentive to improve it. It won't improve their pay and promotions, and the less efficient the bigger an empire can be built by managers.
