Welcome! This is a community for all those who are interested in protecting their privacy.
PS: Don't be a smartass and try to game the system, we'll know if you're breaking the rules when we see it!
Some of these are only vaguely related, but great communities.
If it's into Canada, I don't think you have that option. If it's into the US, then yeah, they have to let you enter, so I assume refusing face scans is allowed. They can certainly detain you, but you have rights. IANAL though, and YMMV depending on the color of your skin and/or accent, unfortunately.
