No. A spouse admitted in TD status may study but is not authorized to work, and that applies regardless of the spouse's own professional qualifications or of any state licence they might obtain. A spouse wanting to work would need their own authorization on a separate basis.
A spouse's licence does not create work authorization
A second clinician in the household needs an individual employment plan. TD does not authorize employment, and a state licence does not supply immigration work authorization. Review proposed remote activity or an unpaid placement specifically rather than assuming it is exempt. If two incomes are essential, resolve the spouse’s own route before committing to housing based on both salaries.
A spouse and unmarried children under 21 may qualify for TD status, with steps that depend on each person's nationality. An eligible spouse or unmarried child under 21 may use TD under its conditions; the principal’s TN does not extend professional permission to them. U.S. practice requires the applicable state nursing authorization, and health-care-worker certification may also be required for admission; an employer may make an offer contingent on completing those steps. Remote work from inside the United States needs its own lawful basis. Only a status that independently permits employment changes that answer.
