Here we go again. You cannot just "leave" the USA. You cannot just denounce your citizenship either, it doesn't work like that. If you don't want to be a US citizen you are going to need a bunch of money and plenty of time.
First off you will need to be able to become a citizen of another country. Most times this means you will need to OWN outright some real estate in this other country. Then you will have to live there for a while and pay the taxes of that country PLUS you will be taxed by the US government as if you were still working in the US. Some countries require that you have a job or produce income to become a citizen. So if you moved to some country where the Income tax rate was around 30%, you will also have to pay the US rate of about 35% on top of it. So you are going to have to survive on 35% of your income until you can actually denounce US citizenship. Then you will have to petition the US government, this process can take months to years depending on how busy the country in which you want to move is. The fees can be exorbitant in the new country, some are $50,000 or more to secure a spot. There are fees on the US side too, all in all about $20,000 in total.
Then once approved you go to an embassy and actually denounce your US citizenship in front of an official and they process the paperwork. They then run background checks to make sure you don't owe any back taxes or have any warrants and such, so this process can take up to 2 years before someone gets cleared. Hopefully this entire time you new host country hasn't changed any of its rules during concerning your status or your VISA time doesn't run out, you get deported and have to start all over again.
Then you can "leave " the USA.
On average its a 4-7 year process that costs on average over $100,000 to accomplish.
The wealthier you are the quicker the wheels can be greased. 18 months and $250,000 on average.
