Same question on dual nationality, is it okay to travel outside of the U.S. on my other passport?
While the U.S. does not prohibit dual nationality, Americans must comply with U.S. laws (e.g. federal and state taxes, selective service, and foreign assets control) regardless of their location. Thus, a dual citizen who travels to Cuba on another passport, may violate U.S. law and be subject to criminal or civil penalties.
