I'm an American expat in Germany. I've never had my fingerprints checked, neither in the US not at any country borders. Could be a privilege stemming from US/EU diplomacy but I've never heard of them checking anyone else's fingerprints.

For foreigners entering the US fingerprints are taken in ~100% of the cases at airports. Land borders seem to be an exception.

For the EU it's very rare as far as I know, both for EU citizens or foreigners.

Not for Canadians - unless this recently changed, fingerprints are not taken for a Canadian flying in from Canada, or from Mexico.

Interesting. I'm a student from Europe. All of my international friends have the same experience. But Canadian have a very special relationship with the US (like few/no visas...) so I guess I'm not surprised.

Which is fortunate in the EU given the automated passport gates. I can't imagine trying to get Opa to scan his fingerprints in a way that satisfies the automated checking.

EU citizen here; I had the fingerprints checked at US borders.

Last time I renewed my passport finger prints were optional. If you want to visit certain countries like USA you must provide them but you are not generally required.
