In a message released 14 November 2006, during a Vatican press conference for the 2007 annual observance of World Day for Migrants and Refugees, the Pope urged the ratification of international conventions and policies that defend all migrants, including refugees, exiles, evacuees and internally displaced persons. "The church encourages the ratification of the international legal instruments that aim to defend the rights of migrants, refugees and their families," the Pope said. "Much is already being done for the integration of the families of immigrants, although much still remains to be done."
