 In fiscal year 2015, the State Department estimated there were 5,986 applications for renunciation of nationality, and forecast an additional 559 citizenship relinquishments.The discrepancy between this total of 6,545 compared to the 4,279 announced by the Treasury Department is speculated to be at least partly due to different counting of long-term green card holders, but no department of the government has released an official explanation.In 2016, the Treasury Department published 1,151 names of people who expatriated in Q1 FY2016.
