Per the Swedish royal court:

Mr. Christopher O’Neill is and remains an American citizen, and he intends to continue his business activities as before following his marriage to H.R.H. Princess Madeleine. In accordance with royal protocol, a member of the Royal Family should be a Swedish citizen, and should not hold a position of responsibility within business.

This means that, in accordance with these principles, Mr Christopher O’Neill cannot hold the title H.R.H. Prince of Sweden or Duke of Gästrikland and Hälsingland. 

In view of these requirements, Mr Christopher O’Neill has respectfully requested to remain a private citizen and not to be granted royal rank. 

Svante Lindqvist 

Marshal of the Realm
