 If a cardinal priest or a cardinal deacon is later appointed a cardinal bishop (a member of the first order of the College), he is typically transferred from his titular church to the vacant title of a suburbicarian diocese in the vicinity of Rome.Patriarchs of Eastern Catholic Churches who are created cardinal bishops are not assigned titles of suburbicarian dioceses.A cardinal may request that he be transferred to another titular church in a consistory; in addition, when a cardinal deacon opts to become a cardinal priest (usually after ten years), he may request either that his deaconry be elevated "pro hac vice" ('for this occasion') to a title or that he be transferred from his deaconry to a vacant title.
