A TD dependent's status is tied to the principal TN holder's status, not to the employer's corporate structure directly. If the underlying TN classification requires a new determination because of the acquisition, TD status for family members should be reviewed alongside it, since TD depends on the principal maintaining a valid TN classification.
Keep dependent timing linked to the principal case
TD holders, including a spouse and unmarried children under 21, are not separately employment-authorized, and that does not change because of an acquisition. If the principal TN needs an amended filing or new border determination, coordinate family travel and paperwork around the same timeline so that no dependent's status lapses relative to the principal's.
Treat the principal’s status record as the family calendar. Gather passports, proof of marriage or parentage, current admission records, and evidence of each child’s age and marital status. The first review should state whether every intended dependent can be documented and whether travel must occur together or later. A dependent’s nationality can affect visa processing even though dependent eligibility follows the principal classification. Hypothetical example: A meteorologist’s spouse plans to travel two months later with a seventeen-year-old stepchild whose birth certificate does not name the principal. The useful next step is to obtain the marriage record and documents showing the legal relationship before booking travel, not to assume the surname is enough. TD status does not independently authorize work, so a spouse considering employment needs to evaluate that separate limitation before making a relocation decision. Keep expiry dates aligned with the principal’s authorized stay.
Before departure, compare every dependent’s planned admission record with the principal’s expiry date and save electronic copies in a shared file. If the household changes travel plans, recheck the document list; a delayed dependent should not rely on a photocopy without the underlying relationship evidence.
