Read the general eligibility basics overview
The USMCA list includes Dental Hygienist, requiring a baccalaureate or a state or provincial licence, but the category is open only to citizens of Canada or Mexico. A Rothesay dental hygienist who is a Canadian permanent resident and a citizen of the Philippines cannot use TN, whatever her licence and experience. Her Canadian-citizen husband's TN as a mechanical engineer gives her TD status, which permits study but not work. Her own working route has to be built from her own nationality.
Record the facts that differ between the spouses
Hypothetical example: a Rothesay mechanical engineer with a Canadian degree and citizenship by birth receives a TN offer from a U.S. equipment manufacturer. His wife, a licensed dental hygienist who immigrated from the Philippines and holds permanent residence, assumes her profession's presence on the list makes her eligible too. It does not, because the citizenship requirement precedes the profession requirement. The household should write down, for each spouse, citizenship, permanent-resident status, profession, licence and intended U.S. activity. His four facts support a TN application; hers support TD status and study, and any working route for her has to be found elsewhere.
Consider the routes that her nationality does allow
As a TD dependant she may study, which could include the coursework and examinations a state dental board requires for hygienist licensure, so the TD period need not be wasted. Employment would require its own basis: a U.S. dental practice willing to sponsor her under a category available to her nationality, with that category's own rules and, where applicable, annual limits and timing. E-2 is not available to her as a Philippine national absent a treaty basis, and L-1 would require a qualifying year with a related company abroad, which her clinic employment does not provide. Her options should be assessed on those facts rather than by analogy with her husband's.
Weigh the citizenship timeline against the offer
If she is close to meeting the physical-presence requirement for Canadian citizenship, the couple has a real choice: move now with her in TD status and pursue licensure and a sponsored route, or delay his start until she is a Canadian citizen and can apply for TN as a dental hygienist in her own right, subject to holding a state or provincial licence and having a prearranged professional offer. Time outside Canada may affect her presence calculation, so the Canadian rules should be checked before the decision. The employer should be told there is a second timeline in play. A clear-eyed comparison of the two paths, with dates, serves the family better than assuming the faster one is right.
