I would have thought one is not American until one is a citizen.

That's not how Americans view it. The notion of belonging to a nation is very different in the New World, as best exemplified by this map. https://commons.m.wikimedia.org/wiki/File:Jus_soli_world.svg...

This map doesn't say anything about visa holders and green card holders. It is only relevant for persons born in the country, which I'm assuming most visa/green card holders aren't.

It was intended to convey the difference in attitudes, not relevant law.

I got that, but the attitudes about the relevant 'jus' may well be different. It may be as you say it is, but I'm not sure if that's not just a subjective opinion - at least from this graph.
