As Queen Victoria once said: "we are not amused!". She must have meant section 911 of the US tax code.
That is basically what US expats think of the current concept of "Citizen Based Taxation".
The rest of the world follows the logical concept recommended by OECD " Residence Based Taxation". Why? Jurisdiction of sovereign nations, simplification and major economic advantages for trading nations.
The current situation is needlessly complex and plays a really active role in reducing US exports.
We leave you, the reader to consider if that is wise...
