If you are a departing international passenger, you do not have to participate in facial recognition processing. Simply let the airline gate agent know, and you will be able to use your regular travel documents to board.
If you are an arriving international passenger from the United States, you can also opt-out; tell the CBP agent no and you will be processed in the traditional manner.
However, if you are an arriving foreign national, you will be required to participate in facial recognition processing.
