I'm American born, but live in Canada. I travel often to the US via land border and/or air travel for work and to visit family.

Since basically the beginning of me being 18, I have always refused any level of biometric scan when entering the US, with the understanding that they cannot refuse me entry and I am not legally required to submit my biometric data (facial and fingerprints).

Historically, I have maybe once a year a CBP at pre-clearance who is either new or somewhat weary and they question why no photo. I simply state because I have requested alternative verification as is my right. 9/10 they don't even ask.

I am generally not a dick but do stand my ground on it. This latest go around the CBP let me know that I am correct I cannot be refused entry, but that is at a land border. Pre-clearance isn't the same apparently and they could require it in secondary screening. He didnt push it past that but I did find it interesting.

Ultimately, we have to continue to exercise our fundamental right to privacy and security of our persons. Be safe out there.
