Read the general eligibility basics overview
Hypothetical example: in a Hampton household the wife is a British citizen and a Canadian permanent resident working as a registered nurse; her husband is a Canadian citizen and a heavy-duty equipment mechanic. A U.S. employer wants to hire her. TN is unavailable to her because she is not a Canadian or Mexican citizen, and unavailable to him because his occupation is not on the professional list. Neither can carry the other as a dependant, so the family's route has to be built somewhere else entirely.
Two separate reasons, one result
Hypothetical example: a Hampton couple assume that between them they have the ingredients for a TN move, since one is a Canadian citizen and the other works in a profession that appears on the list. The requirements do not combine. TN needs a single person who is both a Canadian or Mexican citizen and qualified in a listed profession with prearranged work in it. The wife is a registered nurse, which is on the list with its own licensing rule, but her citizenship is British and permanent residence is not citizenship for this purpose. The husband is a Canadian citizen, but heavy-duty equipment mechanic is not a listed profession, so he has nothing to apply for. Because neither can obtain principal status, neither can bring the other as a TD dependant.
The routes that remain go through the employer or through time
Hypothetical example: the same U.S. employer genuinely wants the nurse and asks what else is possible. The realistic answers involve either the employer doing more or the family waiting. An employer-sponsored petition in a category that does not depend on Canadian citizenship is the usual direction, and which category fits depends on the role, the qualifications and the employer's willingness to file and to wait. Some categories are subject to annual numerical limits, which affects timing rather than eligibility. Separately, if the wife is eligible to apply for Canadian citizenship, obtaining it would open TN for her later, with her husband then accompanying as a TD dependant. That path is slow and should be assessed on her actual residency history rather than assumed.
Plan the working spouse's position from the start
Hypothetical example: the couple focus entirely on getting the nurse to the United States and treat the mechanic's situation as something to solve later. It is better solved first, because it usually constrains the choice. If the family moves on a status that gives him no work authorization, the household is on one income in a new country, and he may have no route of his own. Some derivative statuses do permit spousal employment and others do not, and that difference should drive which category the family pursues rather than being discovered afterwards. Write both people's positions out before choosing, and confirm separately what state licensing the nurse will need, since that timeline runs in parallel and is not an immigration question.
