The spouse needs the appropriate actual status basis. A qualifying L spouse may work incident to valid status with appropriate evidence; the certificate does not create that permission.
Keep professional skill and status distinct
Eligible dependents include a spouse and unmarried children under 21. Children receive no spousal work benefit. Similar qualifications do not merge separate immigration records.
Once L-1B status is approved based on the specialist's company-specific procedure knowledge, family members qualify for L-2 status through their relationship to the specialist, not through any separate evaluation of the underlying specialized-knowledge claim. Record each family member's intended work or study along with age and status dates, and confirm the spouse's current status documentation rather than assuming a particular authorization document is automatically required. The principal must independently show a qualifying related organization, an uninterrupted foreign-employment year within the relevant prior three-year period, and genuinely specialized company knowledge for the US assignment. If the family intends to stay for the whole assignment, list each person's passport and Canadian status, since a spouse or child who is a permanent resident rather than a citizen will process L-2 at a consulate rather than at the border. A school enrolment, a resignation letter and a lease each convert a plan into an obligation, and every one of them depends on a status that is not settled until the specialized-knowledge account and the qualifying year abroad have both been assessed.
