Read the general eligibility basics overview
Permanent residence in Canada is a Canadian status with no effect on U.S. eligibility, and TN and E-2 are reserved for Canadian citizens. In a Shannon household where the Canadian citizen's posting is set by her employer and the permanent-resident partner is the one with a U.S. offer, the partner's own nationality and the corporate structure of his employer decide his route, and nothing about the citizen's status transfers to him.
Strip the household down to the person with the U.S. opportunity
Hypothetical example: a Shannon couple consists of a Canadian citizen whose posting and location are decided by her employer, and her husband, a Portuguese citizen with Canadian permanent residence, who works as a quality inspector for an aerospace-parts supplier. The supplier's U.S. affiliate wants him for two years. His wife's citizenship is irrelevant to his U.S. eligibility; so is his PR card. He is, for U.S. purposes, a Portuguese national employed by a Canadian company with a U.S. affiliate. TN is closed to him. E-2 in his own name would depend on Portuguese treaty status and an investment, which is not this scenario. L-1 is open if the corporate and employment facts fit.
Test the L-1 facts, because nationality does not matter there
L-1B requires that the supplier and its U.S. affiliate be related as parent, subsidiary, branch or affiliate, that he has worked for the group for a continuous year in the last three, and that his knowledge is specialized to the company's product or processes rather than general inspection skill. L-1A would require a primarily managerial role. Both are indifferent to his passport. If the affiliate relationship or the specialized-knowledge case is weak, the alternative is an employer-sponsored petition in a category that does not depend on the corporate link, which the U.S. affiliate would need to file in its own right. His wife's employer-determined location is recorded as a fact outside the review.
Keep the Canadian obligations visible while solving the U.S. one
A two-year absence on a U.S. assignment affects the husband's Canadian permanent-residence obligation and any citizenship application in progress, and the household should raise both with a Canadian adviser before he accepts. A Canadian citizenship ceremony during the assignment would open TN for future opportunities but does nothing for the current one, so no U.S. offer should be conditioned on it. If the couple's children hold Canadian citizenship through their mother, that is noted per child; it does not change the father's route. The plan should end with one timeline showing the U.S. petition steps, the PR residency count and the citizenship application side by side.
