> it is the traveller's responsibility to have valid documents and be familiar with the current entry regulations

This response from the Norwegian foreign office makes it seem like the man lacked proper documentation, which led to the search. However, it’s unclear to me whether the comment is specific to this case or just a general statement.

Bullshit. They won't let you board a plane heading towards the US without a valid ESTA/Visum and Passport

The airline and airport have no way to check your Visa or ESTA status.

[hermanzegerman]

Wrong. DHS tells the Airlines your ESTA Status, so they won't let you board if you don't have a valid one. And if you don't have one, the Airlines will check for a Visa

"DHS communicates a traveler’s ESTA status to the carriers. However, DHS recommends that travelers print out the ESTA application response as a record of their ESTA application number to confirm their ESTA status."

They also have DHS Agents on the departure Airports, which already tell the Airlines which Passengers aren't allowed to board. If the Airlines violate against this, they face severe consequences like a ban from US Airspace
