As a general rule, government websites tend to assume that if you're visiting them you understand that all information is directed at residents of the country the government is in charge of.

This is not limited to US entities: data.gov.uk purports to provide "data published by central government, local authorities and public bodies" without specifying which country it belongs to, yet I can't find my local information there!

.gov is a US domain.

Yeah my mistake, I should've said "around the US"
