Hey, this little tidbit wasn't there before.
US-VISIT will collect information on foreign visitors’ arrivals and departures – date, nationality, classification, and biometric identifiers. The information will be stored in databases maintained by DHS and the Department of State as part of an individual’s travel record. The current plan is to maintain the data for up to 100 years, but that is being reviewed to ensure that we only retain the data as long as needed. [Emphasis mine.]So if I visit the US, even under the visa waiver program, they have me on file for a fucking century? Fuck that.
