although the oath of naturalization for the united states contains a statement renouncing "allegiance and fidelity" to other countries, the republic of china (the formal name of taiwan) does not recognize this renunciation as sufficient for the termination of roc nationality, and requires a person who wishes to renounce roc nationality to take another oath before an roc consular officer. all renunciations are subject to approval from the ministry of the interior, and the ministry may deny a person's application under taiwanese law. without formal renunciation, the roc government considers its emigrants with american citizenship to continue to be nationals of the roc. acquiring us citizenship has no effect on the holder's status as a national of roc, which makes taiwan-born americans still eligible to vote in the roc elections, provided that their household registration is still intact in taiwan.
