Does overflying the US in low Earth orbit count as reentry? Or do you need to re-enter the atmosphere im order to re-enter?
The Kármán Line is also generally accepted to be the boundary of outer space, set at 100 kilometers above ground.
The ISS orbits at something like 415km above Earth.
I'm no lawyer but is seems plausible to say no, orbiting above 100km of altitude over the USA would not be considered entry into the country.
