The Agreement between the Government of Canada and the Government of the United States of America on the Sharing of Visa and Immigration Information will enter into force as soon as both Parties have completed their respective national procedures necessary for their entry into force. In addition, there is a provision stating that the agreement itself must be reviewed every six years by the three nations, with a sunset clause of 16 years. The agreement can be extended by 16 years during the six years of revision.  The introduction of the sunset clause puts more control in the organization of the future of the USMCA in the hands of national governments. However, there is concern that this could lead to greater uncertainty. .
