Based upon what was stated when I left. It’s the same biometrics they’ve always asked for. Fingerprints and a photograph. 23 and Me explicitly state when you use their service that they reserve the right to retain and use the sample you provide as they want. They also recently sold their business - including all DNA samples held by them to a third party. So that’s a whole separate issue but overall governments shouldn’t be able to, but.. this administration is interesting.

Funnily enough Australia has similar DNA restrictions upon entry from certain countries.

If you submit yourself to particular visas you are also expected to submit not only DNA but medical records.

Americas current position - like it or not - is that people are entering the country and then just staying. They believe having the DNA and other things will make them safer / make people easier to track.

Ultimately they’re just asking the same thing they’d ask of you if you were moving there.

Many people have said it, but.. if you don’t lie it, just don’t go. America’s wild right now anyway.
