J.J. Rowling is an American citizen? Brit bitch flees one socialist crap hole and wants to be taxed to the wazoo here? What an idiot.
Nope she is British and lives in Europe. However,who knows, she may have a residence here too—if so, hope she sells it and does not return ;)
Like any Brit celebrity I'm sure she uses America as a residence in order to avoid the crushing taxes in the UK and the rest of Europe.
