Members of Congress and the administration shall hold ONLY United States citizenship.
Why is this important?
I feel that one can serve only master at a time. No matter what coiuntry in which a person holds citizenship, partial allegiance is not possible and should not be allowed either in Congress or in any other branch of government I would also include the State Department as well as the military services. If one wants to serve they should be willing to give up citizenship in another country A number of countries do not permit service by dual citizenship holders. The U.S. should be one of them.
