"Savornan v. United States, 338 U.S. 491, 338 U.S. 500 (1950); N. Bar-Yaacov, Duel Nationality xi and 4 (1961). These problems are particularly acute when it is the father who is the child's alien parent and the father chooses to have his family reside in the country of his own nationality. The child reared, at best, in an atmosphere of divided loyalty. We cannot say that a concern that the child's own primary allegaince is to the country of his birth and of his father's allegiance is either misplaced or arbitrary."
