The United States, Mexico and Canada recently reached a trilateral agreement on September 30, 2018 as part of the renegotiation of the North America Free Trade Agreement (NAFTA).

Known going forward as the United States-Mexico-Canada Agreement (USMCA), the immigration provisions in the agreement appear not to have suffered any significant changes and have been rearranged somewhat, to the relief of many on all sides of the border.

Some minor changes of note regarding the professional occupations include the addition of the professional title of "actuary" under the mathematics profession and the "plant pathologist" occupation under the biologist profession. Business visitors entering the United States for certain purposes, which include the engagement in commercial transactions, public relations and advertising, tourism, tour bus operations and translation services, now each have their own headings instead of being placed under a "General Service" section for B-1 business visitor admissions.

It is expected that the new agreement will be ratified and signed by President Trump after the mid-term elections.
