No. Your licence and TN arrangement do not authorize the spouse’s employment. TD permits study but not employment. A spouse seeking professional work needs an independent assessment of their own immigration permission and any required practice qualifications.
Treat a second career as a separate project
If both spouses intend to work in architecture, gather separate offers and qualification records as appropriate. Do not assume one professional registration or one employer support letter establishes both cases. Household plans should follow the permissions each person actually obtains.
TD status is available to a qualifying spouse and children, but it does not authorize employment; calling services occasional, remote, unpaid, or consulting does not settle whether they constitute US work. Sequence dependent applications with the principal’s classification and avoid booking an employment start for a TD spouse. Derivative TD status permits residence and study but carries no work authorization at any stage, and no waiting period changes that. The relationship must be a legally recognized marriage, so a common-law partner is not a spouse for this purpose and needs a separate route. Whether remote work performed in the United States for a foreign employer is treated as U.S. employment is not answered by a simple rule, so it needs advice and a check of current official guidance before anyone relies on it.
