Renouncing US Citizenship: A New Trend?

"Though the Saverin and Rich cases attracted the spotlight, the trend of citizenship renunciation is evident.  Quarterly published figures from the IRS indicate that the number of US citizenship renunciations has risen in recent years — to 1,780 in 2011, from 1,485 in 2010 and 731 in 2009.  Prior to 2009, the numbers ranged from 200 to 400 cases annually." - MPI, Sept. 2012.
