They can. Civil documents issued in French, including marriage and birth certificates, need accurate translations that preserve names and wording. Note also that TD status permits study but does not authorize a spouse to work, so a spouse's own professional title has no bearing on TD work rights.
Translate family records the same way
Relationship evidence is what supports a spouse's or an unmarried child under twenty-one's TD eligibility, so those documents need the same care: full translation, original preserved, names spelled consistently across every record. Where a name appears differently on a passport than on a birth or marriage certificate, flag the discrepancy for counsel rather than correcting it silently in the translation.
A spouse and unmarried children under 21 may qualify for TD, with steps depending on each person’s nationality and circumstances. Children may study while maintaining applicable status but do not gain employment authorization solely through TD. TD status permits study but not employment, and paid tutoring performed in the United States is employment even if the students are Canadian or pay by e-transfer. A spouse who wants to work should first qualify for and obtain an independent status authorizing that activity.
