Exempt Catholic Dioceses (directly subject to the Holy See)
These (arch)dioceses are exempt from belonging to any ecclesiastical province, hence only the Vatican can exert the authority and coordinating functions normally falling to the Metropolitan Archbishop. They are grouped here geographically. Nevertheless, most belong to an episcopal conference, in which case the more relevant mention is in its geographical region, as exempt dioceses as such do not have specific ties with each other. Military ordinariates are in pastoral charge of the troops of a state, but may be vested in a Metropolitan Archbishop, typically in the national capital. Also generally exempt are the apostolic prefectures and apostolic vicariates, which tend to be temporary missionary dioceses, expected to become part of an ecclesiastical province when promoted to regular (arch- or suffragan) bishopric. The Personal Ordinariates for former Anglicans (who left the Anglican Communion for communion with the Holy See) are allowed to use the Ordinariate Use, which is counted as a variant usage of the Roman Rite (unlike the Eastern churches' five distinct rites). Eastern Ordinariates are in pastoral charge of all Eastern Churches, of only those of Byzantine Rite or even just of the Armenian Rite, in one or more states of various Catholic churches without any proper diocese there, but are usually vested in a Latin Catholic Metropolitan Archbishop, often in the capital. Disregarded are many episcopal or archiepiscopal prelates in the Roman Curia, as their dicasteries don't constitute dioceses, although many posts there require by law or custom a bishop or an archbishop (usually titular), just as the Vatican's diplomatic posts in nearly every national capital.
Universal or transcontinental exempt dioceses (not counting minor dependencies) The personal prelature (a unique status) of Opus Dei, with a cathedral see (Santa Maria della Pace ai Parioli) in Rome, ranking as bishopric. The transcontinental Apostolic Administration of the Caucasus covering both Georgia (including breakaway self-declared states Abkhazia and South Ossetia) and Armenia, with cathedral see at Tbilisi (Georgia). The Personal Ordinariate of Our Lady of the Southern Cross (for former Anglicans in Australia and Japan).
