How will you apply for citizenship???? You can't say you are a US citizen.. How will you get out of the US. Passport no good anymore. How will you stay in the US--You need some type of 'green card', can't get one in the U S. Go to Mx. but they only issue visitor cards to their citizens. I would imagine thats the same for any country. For another country to accept you as a citizen you would have prove yopu would be an asset to their country. You could not work in this country without a work permit. Etc etc etc. If you really want to avoid taxes change your lifestyle and learn to 'fly under the radar'. It can be done but you have to know what you are doing.
