After 2016, the approval of the covenant was scheduled for 2018; the members of the General Assembly of the United Nations signed unanimously the Declaration of New York. This document contains elements aimed at improving action on people as refugees and migrants all over the world. The representation of the United States in the UN considers that the covenant is incompatible with the immigration policies of Washington.
The United States ambassador to the United Nations, Nikki Haley, said in a statement to the world organization: "Our decisions on immigration policies should always be made by Americans and only by Americans."
During the administration of Donald Trump this is the fourth dropout of the United States from international accords. It joins the Global Pact of Refugees and Migrants, the Trans-Pacific Partnership, the Paris Agreement and Unesco.
