↑ The Belarusian Greek Catholic Church is unorganized and has been served by Apostolic Visitors since 1960.
1 2 The Greek Byzantine Catholic Church comprises two independent apostolic exarchates covering Greece and Turkey respectively, each immediately subject to the Holy See.
1 2 The Russian Greek Catholic Church comprises two apostolic exarchates (one for Russia and one for China), each immediately subject to the Holy See and each vacant for decades. Bishop Joseph Werth of Novosibirsk has been appointed by the Holy See as ordinary to the Eastern Catholic faithful in Russia, although not as exarch of the dormant apostolic exarchate and without the creation of a formal ordinariate.
↑ The Ruthenian Catholic Church does not have a unified structure. It includes a Metropolia based in Pittsburgh, which covers the entire United States, but also an eparchy in the Ukraine and an apostolic exarchate in the Czech Republic, both of which are directly subject to the Holy See.
↑ Five of the ordinariates for Eastern Catholic faithful are multi-ritual, encompassing the faithful of all Eastern Catholic rites within their territory not otherwise subject to a local ordinary of their own rite. The sixth is exclusively Byzantine, but covers all Byzantine Catholics in Austria, no matter which particular Byzantine Church they belong to.
↑ The six ordinariates are based in Buenos Aires (Argentina), Vienna (Austria), Belo Horizonte (Brazil), Paris (France), Warsaw (Poland), and Madrid (Spain).
↑ Technically, each of these ordinariates has an ordinary who is a bishop, but all of the bishops are Latin-rite bishops whose primary assignment is to a Latin see.
