If they determined you did for taxes, it's a no-no:
Former U.S. citizens would 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 Program. If unable to qualify for a visa, the person could be permanently barred from entering the United States.
If the Department of Homeland Security determines that the renunciation is motivated by tax avoidance purposes, the individual will be found inadmissible to the United States under Section 212(a)(10)(E) of the Immigration and Nationality Act (8 U.S.C. 1182(a)(10)(E)), as amended.
