The Archeparchy of Philadelphia's territorial jurisdiction includes the District of Columbia, Virginia, Maryland, New Jersey, and the eastern and central portions of Pennsylvania.

[1][2] Ukrainian Greek Catholics in the United States were given sui iuris status as an ordinariate for the faithful of eastern rite by Pope Pius X in 1914.

Prior to that, all Ukrainian Greek Catholics had been under the jurisdiction of the local Latin Church ordinary.

In 1983, the Archeparchy lost part of its territory to the new (though still suffragan) Eparchy of Parma erected by Pope John Paul II.

In addition, Ukrainian President Viktor Yushchenko and his wife paid a state visit to the Archeparchy and the Cathedral in 2005.
