I'm close to doing it. Since the US seems to be the only country that requires expats to file taxes and pay taxes that pretty much seals the deal. I could get nailed to the wall if I sell a business venture for a great deal of money, or if a relative leaves me money. I am also a citizen of New Zealand so plan to give up my US passport. One concern is that I have heard even when you do this they force you to remain a US citizen for 8yrs and you must continue to file taxes for 8yrs after renouncing. Is this still true? If so how can they force me to be a citizen of their country? Would this not be a violation of my human rights? I would love to hear from anyone that has renounced and what your experience was like. I have no desire to set foot in the US again, my home is here now.. Thanks

AFAIK, all you have to do is go to a US embassy in any country and renounce your citizenship. They'll confiscate your passport and you'll become a stateless person. You should know that people who renounce their citizenship aren't exactly welcomed back to the US. You may have problems returning to the US, even for a visit. Being a stateless person has some serious disadvantages, so you might want to think about grabbing citizenship of some country first, before renouncing the US citizenship.

I don't know whether it is possible to renounce your citizenship while you're still in the US.

Fun fact: Einstein renounced his German citizenship and became a stateless person for a while, before getting Swiss citizenship.
