Minor correction: Not 10 years after you leave, but for 10 years after walking into a US embassy and relinquishing citizenship. Only then, you have the privilege to pay tax to a state you no longer are a citizen of for the next 10 years. For all other US citizens working overseas, you owe uncle sam a tax return every year no matter if it&#x27;s for 5 years or 50. Only two nations in the world tax their citizens who live abroad. The other one is an African dictatorship.
