How is a US person defined according to the export regulations?

I found the definition below from the University of Vermont

A "US person" is a citizen of United States, a lawful permanent resident alien of the US, (a "Green Card" holder), a refugee or someone here as a protected political asylee or under amnesty. US persons also include organizations and entities, such as universities, incorporated in the US. The general rule is that only US persons are eligible to receive controlled items, software or information without first obtaining an export license from the appropriate agency unless a license exception or exclusion is available.
