As a rough approximation, if you’re a US citizen, then You must file a US income tax return. The US taxes your worldwide income regardless of where it’s earned. BUT under most circumstances you would get a credit against what you owe the US for what you pay the country in which you earned the money and also wanted to tax you (no double taxation in theory)
It’s kind of a pain for someone living in say Kenya which doesn’t have a tax treaty with the US, but it’s not totally absurd to think you owe something to a country whose citizenship you continue to benefit from.
