Before you take this step, go live in Nigeria where there is only anarchy. Bribery is the way of life, no one does anything unless they are bribed first. The police will chase you down and take your money. People do not respond to police lights and sirens if it means stopping in an isolated area. All mail is opened, magazines read, and anything of value taken by post office employees. The roads are nearly nonexistent, and are clogged with armed, uniformed men who will take anything you have of value. There are no free elections and if you speak out against the government, you stand a good chance of being hung. If you and your neighbor have a beef, and you decide to take it to court, be prepared to pay the judge, the person with the most money will win. If you do this for a year and still want to renounce your citizenship, just leave the country and never come back.
Lucy, I read your other questions, but not any of your answers. I think it's a good idea to end your relationship with U.S. go to another country and apply for citizenship. During that process, you will have an opportunity to dissolve your American citizenship. Go overseas or south. Don't go north.
If you want to renounce US citizenship, you must do so voluntarily and with intent to relinquish your U.S. citizenship, in the presence of a U.S. consular or diplomatic officer. Renouncing citizenship is irrevocable except in rare cases of judicial appeal but I don't know how frequently that happens.
