Imprisoned in Istanbul, Agca wrote a letter to Polish President Lech Kaczynski asking to become a citizen of "that dignified homeland of Karol Wojtyla (the Pope's civil name)," a man he considers to be a "messiah."
Agca said in his letter he is "the spiritual brother of John Paul II, who was a wonderful, perfect human being."
Legal proceedings have begun, the Sofia news agency said, and Kaczynski will make the final decision.
