What is the reason for the United States to withdraw from the immigration agreement?

The Global Immigration Agreement aims to accept a certain number of immigrants (including refugee resettlement) within the scope of the agreement for the member countries that have joined. The agreement provides for immigration export and immigration import. Under this premise, the United States proposed to withdraw from the immigration agreement out of self-protection, that is, the United States does not need to bear the risks and brain drain caused by immigration and resettlement of refugees. At present, based on this, the United States has put forward the priority industrial recovery plan of the United States. The United States withdrew from the immigration program to protect itself and did not want to accept more immigrants or refugees. More immigrants will divide American interests, and more refugees will affect American social stability. According to the selfishness of Americans, it is understandable to withdraw from the immigration agreement!
