I don't see anything about the potential investor being American, only that they are a "US-based family" - and there's a quite a few us of us here that fit that bill and are not American (I'm not the investor, btw).
Enjoyed the analysis of the "2017 Trump Tax Reforms' though. Thousands of pages of complex tax law distilled into "you can write off overseas losses".
BTW, not saying I'm in favour of this - I voted against allowing overall control for any investor and I'll need to see some serious detail before I continue to contribute to the Society.
