The proclamation sought to "fully restrict" arrivals from Afghanistan, Burma, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen.
It also "partially" restricted arrivals from Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela.
