Can you keep your Taiwan citizenship when you become a U.S. citizen?
Allowed
Yes, in general
Taiwanese nationals who become U.S. citizens generally keep their ROC nationality, since Taiwan recognizes dual citizenship.
What the law says
- The law recognizes dual citizenships, acknowledging support given by overseas Chinese historically.
- ROC nationality can be relinquished by application to the Ministry of the Interior, provided the person has acquired another nationality or is married to foreign nationals.
- Relinquishment is voluntary; the excerpt does not state that acquiring another citizenship automatically causes loss.
- Exception: obtaining a PRC passport or household registration causes loss of ROC passport and household registration in Taiwan.
- That PRC restriction does not apply to Hong Kong and Macau residents who have settled permanently in Taiwan and gained citizenship rights.

What about the U.S. side?
The United States allows dual citizenship. At the oath ceremony you promise to renounce allegiance to other countries, but U.S. law does not make you formally give up your other passport. The question is only whether Taiwan lets you keep yours.
