Read the general eligibility basics overview
Hypothetical example: Nnamdi is a Nigerian citizen and a Canadian permanent resident who has worked at an East Ferris manufacturer for six years. His employer's American customer wants to hire him and assumes a TN is available because he lives in Ontario. TN is limited to citizens of Canada and Mexico. A permanent resident card is not citizenship, length of residence does not substitute for it, and the routes actually open to him are different in kind rather than in quality.
Why the distinction is absolute
TN eligibility rests on citizenship, and the evidence for it is a Canadian passport or a citizenship certificate. A permanent resident card proves lawful status in Canada and nothing about nationality, so no amount of tenure, tax history or provincial licensure changes the answer. The same distinction runs through other routes: an E-2 investor needs treaty-country nationality, which in a Canadian case means citizenship rather than residence. Nnamdi's own citizenship may matter here, since a national of a treaty country has that country's E-2 route available regardless of where he lives. The first step in his case is therefore to write down every citizenship in the household, because the analysis branches on exactly that.
The routes that never depended on being Canadian
L-1 does not ask about nationality at all. If Nnamdi's East Ferris employer has or opens an American parent, branch, subsidiary or affiliate, and he has one continuous year of qualifying employment with the group abroad in the preceding three years, an L-1A or L-1B petition turns on his role and the corporate relationship rather than his passport. The employment-based immigrant categories likewise turn on qualifications and, for most, an employer willing to sponsor and to complete a labour market test. Employer-sponsored temporary categories exist as well, with their own numerical limits and timing. None of these is a lesser version of TN; they ask different questions, take longer, and several of them lead where TN does not.
What to settle before anyone applies
Three things belong on a page before his employer commits to a date. His citizenship documents and his Canadian status documents, kept apart, since extended time in the United States raises questions about maintaining permanent residence in Canada that are a Canadian matter and still a real one. The household's citizenships, including any that open a treaty route. And the American employer's corporate position, since whether it is related to his current employer decides whether L-1 exists at all. If he is also pursuing Canadian citizenship, the expected grant date is worth knowing, because a route closed today may open later, and that changes what is worth building now.
