Without transparency on dual citizenship, Americans remain in the dark, free to speculate on which representatives may have divided loyalties. Current entries on the Internet reveal a wide range of such speculation. The lack of transparency is dangerous, for it erodes trust in government, creating credibility doubts where there should be none and allowing some conflicts to continue undetected, without question or debate.

Secondly, we need more media attention to the subject of dual citizenship. Senator Ted Cruz and Representative Michelle Bachman both received wide press coverage, when they renounced their Canadian and Swiss nationalities, respectively.
Stanley Fischer, who currently serves as vice chairman of the U.S. Federal Reserve, became an Israeli citizen in 2005 while retaining his American citizenship. Prior to his appointment to the Fed in 2014, he served for eight years as governor of the Bank of Israel.
