Investigation of the circumstances, including the timing, under which the Oswalds obtained permission from the Soviet Government to leave Russia for the United States show that they differed in no discernible manner from the normal. The Central Intelligence Agency has informed the Commission that normally a Soviet national would not be permitted to emigrate if he might endanger Soviet national security once he went abroad.[C6-287] Those persons in possession of confidential information, for example, would constitute an important category of such “security risks.” Apparently Oswald’s predeparture interview by the MVD was part of an attempt to ascertain whether he or his wife had access to any confidential information. Marina Oswald’s reported interview with the MVD in late 1961, which was arranged at her request, may have served the same purpose. The Commission’s awareness of both interviews derives entirely from Oswald’s and his wife’s statements and letters to the American Embassy, which afford additional evidence that the conferences carried no subversive significance. It took the Soviet authorities at least 5½ months, from about July 15, 1961, until late December, to grant permission for the Oswalds to leave the country. When asked to comment upon the alleged rapidity of the Oswalds’ departure, the Department of State advised the Commission: * * * In the immediate post-war period there were about fifteen marriages in which the wife had been waiting for many years for a Soviet exit permit. After the death of Stalin the Soviet Government showed a disposition to settle these cases. In the summer of 1953 permission was given for all of this group of Soviet citizen wives to accompany their American citizen husbands to the United States. Since this group was given permission to leave the Soviet Union, there have been from time to time marriages in the Soviet Union of American citizens and Soviet citizens. With one exception, it is our understanding that all of the Soviet citizens involved have been given permission to emigrate to the United States after waiting periods which were, in some cases from three to six months and in others much longer.[C6-288]
