The reduction in tax is still substantial.
As far as I'm aware, its the only nation that taxes its citizens in that way.
I’m not American so it’s not my problem, but it’s what I hear from other tax exiles.
My parents are American but given the choice for me to become American I declined due to the whole tax issue.
there is a "physical presence test" where you need to be resident outside the USA for 330 days or more a year.
