You can't renounce your citizenship whilst in the US. You have to do it at an embassy. On statelessness: Persons intending to renounce U.S. citizenship should be aware that, unless they already possess a foreign nationality, they may be rendered stateless and, thus, lack the protection of any government. They may also have difficulty traveling as they may not be entitled to a passport from any country. Even if they were not stateless, they would still be required to obtain a visa to travel to the United States, or show that they are eligible for admission pursuant to the terms of the Visa Waiver Pilot Program (VWPP). If found ineligible for a visa or the VWPP to come to the U.S., a renunciant, under certain circumstances, could be barred from entering the United States. Nonetheless, renunciation of U.S. citizenship may not prevent a foreign country from deporting that individual back to the United States in some non-citizen status. http://travel.state.gov/law/citizenship/citizenship_776.html http://travel.state.gov/law/citizenship/citizenship_776.html
