No title of nobility shall be granted by the United States: and no person holding any office of profit or trust under them, shall, without the consent of the Congress, accept of any present, emolument, office, or title, of any kind whatever, from any king, prince, or foreign state.
Does foreign citizen count?
I would say “very likely”.
Only if he was holding any office of profit or trust at the time it was granted.
Foreign citizenship is not an office, present, emolument or title.
