Similarly. the present law is oblivious to the needs of mentally retarded children. There is the case of a 5yearold child. whose father is a doctor presently employed by a foreign city as its chief pathologist. He had an approved firstpreference visa petition filed in his behalf by one of our large city hospitals and by an outstanding medical school which wanted him to join its faculty. The child was denied a visa as a mentally retarded alien. This retardation was due to a birth injury. The father would not come to the United States if his child could not accompany him. his wife. and their other child.
