TN: the USMCA professional visa for Canadians and Mexicans
The TN lets Canadian and Mexican citizens work in the United States in one of the professions listed in the treaty (engineers, accountants, scientists, computer systems analysts, management consultants, nurses, teachers and others) with a US employer's offer. There is no annual limit and no lottery. Canadians apply at a port of entry with the offer letter and credentials and can be admitted the same day; Mexicans apply at a consulate. It is granted for up to 3 years at a time and can be renewed indefinitely, though it is a temporary status and intending immigrants must be careful.
Education, not legal advice.
