Read the general eligibility basics overview
A Saint-Constant permanent resident may be a Mexican citizen. TN nationality eligibility is not limited to Canadian citizens, but the applicable documentation and professional conditions must still be assessed for the actual applicant.
Identify the citizenship that supports the proposed category
Canadian permanent residence is not Canadian citizenship. TN can concern eligible Canadian or Mexican citizens with the listed professional qualifications and arrangement. Record the actual Mexican citizenship evidence rather than misdescribing Canadian residence as the nationality basis.
Keep the process specific to the person
Do not apply a Canadian citizen’s visa-document treatment automatically to a Mexican applicant. Identify the actual category and applicable process before travel or work. A qualifying nationality is one condition, not the entire professional assessment or an immediate work authorization. Ask which office issues each document the process requires, and how long that office says it takes, then order them so that nothing waits on something nobody has requested. A file assembled in the order the documents happen to arrive is a file assembled in the order the slowest office chose.
Compare another route only through its own conditions
L requires qualifying foreign employment, a qualifying corporate relationship, required international business and the actual U.S. role. E-2 requires relevant treaty nationality, qualifying ownership and control and substantial lawful funds committed at risk in a real nonmarginal enterprise. Residence in Saint-Constant does not replace those facts or create different U.S. federal rules. Each of those routes is proved by a different set of records: employment and corporate documents for one, ownership, funding and enterprise documents for the other. Before comparing routes, list which of those records already exists for this applicant, because the comparison usually turns on what can be evidenced rather than on what would be preferable.
Which document proves nationality, and which one only proves residence
Two documents in a wallet are routinely treated as interchangeable and prove entirely different things. A permanent resident card establishes a right to live in Canada; it says nothing about citizenship, and citizenship is what this category turns on. Nationality is established by a passport or a certificate of citizenship issued by the country of nationality, and the applicant's own document, not a spouse's or a parent's, is the one that counts. Assemble both: the residence document, because it explains where the applicant lives and why the file is being prepared here, and the nationality document, because it supports the category. A weak version of this evidence is an expired passport accompanied by an assurance that a renewal is under way; an expired document proves a past fact and leaves the present one open. Check the spelling of the name across every document at one sitting, since a discrepancy between the nationality document and the professional credentials is easier to resolve now than at a counter. Where a name changed, obtain the record of the change rather than explaining it in a covering note. Hypothetical example: an applicant qualified as a land surveyor holds a valid residence card and an expired passport, and only the second of those documents is on the critical path.
