Citizenship of the United States
A person who is considered a citizen by more than one nation has "dual citizenship". It is possible for a United States citizen to have dual citizenship; this can be achieved in various ways, such as by birth in the United States to a parent who is a citizen of a foreign country (or in certain circumstances the foreign nationality may be transmitted even by a grandparent) by birth in another country to a parent(s) who is/are a United States citizen/s, or by having parents who are citizens of different countries. Anyone who becomes a naturalized U.S. citizen is required to renounce any prior "allegiance" to other countries during the naturalization ceremony; however, this renunciation of allegiance renunciation of citizenship to those countries.
Diane Lee
On 16 January 2009, the American Institute in Taiwan issued a letter to clarify that under United States nationality law, a person may lose U.S. citizenship by committing certain acts with the intention of losing U.S. citizenship, as long as the person's conduct after the said act is consistent with that of a non-U.S. citizen. Lee's lawyer Lee Yung-jan argued that this supported Lee's earlier statement that she had automatically lost U.S. citizenship upon taking office, and that her subsequent conduct such as travelling to the U.S. on a Republic of China passport instead of a United States passport confirmed her intention to lose citizenship. However, the Central Election Commission revoked Lee's status as an elected official in February 2009. The CEC allowed Lee to keep over NT$8.6 million in election subsidies because the Election and Recall Act for Public Servants did not preclude natural-born dual citizens from running in local elections. Foreign citizenship must only be renounced before the oath of office is administered. Her name appeared in the Internal Revenue Service's Quarterly Publication of Individuals Who Have Chosen to Expatriate in the final quarter of 2009.
