TD does not authorize employment. A placement opportunity does not supply a lawful work basis.
Separate the spouse’s proposal
Assess the spouse’s own qualifications, duties and available permission. TD dependants may study but may not work. The principal’s recruiting arrangement does not extend TN employment authorization to another person.
A TD dependant may enrol in school or university, may hold a bank account and may live in the United States for as long as the principal's admission runs, but any employment, paid or unpaid in substance, is outside the status. If the spouse intends to keep earning, raise it with counsel early, since an independent basis takes its own preparation time and may affect whether the move makes sense on one income. TD status carries no employment authorization of any kind, and working remotely for a Canadian employer while physically present in the United States is still work performed in the United States. The principal must independently hold Canadian or Mexican citizenship, credentials matching a listed USMCA profession, and prearranged professional work that excludes self-employment. A spouse who spends long stretches in Canada does not gain work permission in the US by holding TD, and remote or unpaid work is not automatically outside that limit; that question belongs with counsel.
