Imagine someone born in the US. They leave the US at three months old. They live their entire lives in their parents - in their - country. They are educated there. They work there. They don't have a US passport and haven't ever visited the US.
That person should be able to give up their citizenship for free.
Many people even if they don't live in the US get the benefit of people the US citizen. The author didn't live in the US yet still got a Rhodes scholarship.
In your opinion: should that person pay US tax?
