BAGHDAD, Iraq—Citizens of the seven countries identified by President Donald Trump for a 90-day visa ban who hold dual nationality also will be barred from entering the United States, the U.S. State Department said in a statement Saturday.

In a statement that the State Department is due to release, which was reviewed by The Wall Street Journal, the 90-day visa moratorium extends beyond just citizens of Iraq, Iran, Somalia, Sudan, Syria, Libya and Yemen.
