For one, if I'm a business owner/scientist/engineer working on some stuff, they can do "industrial espionage" and give the stuff (or a heads up) to US companies/the army/whoever.
Second, they can use their spying on a country's politicians to influence that country's policy (like spying on a party they don't like in favor of a party that serve's their interests), do market and diplomatic moves against them, etc.
Third, who said foreigners never travel to the US?
