They store the data from everytime you enter and exit the country. For citizens they claim to delete that data after a couple days- but I would not be too confident in that. So if you are a citizen ALWAYS opt out of biometric entry and exit. I’ve multiple times been told it is not an option, then being forced to wait 10 minutes- harassed about why I want to opt out, then it suddenly becomes an option. This is despite CBPs policy that you cannot be penalized for it. I have several audio recordings of this happening because I noticed how much of a pattern it was.

Is what they claim. What you saw may have been about non-citizens
