Pope Leo has confirmed all top Vatican officials in their current roles on a temporary basis, giving him time to decide before making definitive appointments, the Vatican said in a statement on Friday.

As the leader of Vatican City, he is the head of a sovereign nation. But maintaining dual citizenship as a foreign head of state can “raise complex questions of international law,” according to the State Department.

The Vatican says Pope Leo XIV will be formally installed as pope at a Mass on May 18 and will preside over his first general audience May 21. The Vatican on Friday provided a schedule of Leo’s upcoming agenda.
