Calif. DEAR MR. VAN HORN: The President has asked that I reply to your letter of February 28 regarding the issuance of a visa to Mr. Ian Smith who has been invited to speak at your Annual Convention Banquet on May 4. 1969. I also have for reply your letter to the Secretary of State on this subject. Since Mr. Smith was refused a visa in March 1968. he has not reapplied and no definitive decision can be made until a new application is made. If he were to reapply at this time. our decision would have to be made in light of the mandatory United Nations Security Council Resolution of May 29. 1968. which binds the United States and all other States Members of the United Nations to "prevent the entry into their territories. save on exceptional humanitarian grounds. of any person travelling on a Southern Rhodesian passport . . ." and. further. to "take all possible measures to prevent the entry into their territories of persons whom they have reason to believe to be ordinarily resident in Southern Rhodesia and whom they have reason to believe to have furthered or encouraged. or to be likely to further or encourage. the unlawful actions of the illegal regime in Southern Rhodesia . . ." Sincerely yours.
