Read the general life across the border overview
Hypothetical example: a Saint-Maurice agri-food technician is being transferred to a U.S. affiliate on L-1B for up to three years. His spouse is a dental hygienist who wants to keep working, and their child is nineteen and finishing school. Each person's rights follow their own status: the spouse is employment-authorized incident to L-2 status but still needs a state hygiene licence; the child may study on L-2 but cannot work and will lose derivative status at twenty-one. Plan for three people, not for one transfer.
The spouse: immigration says yes, the state board says not yet
An L-2 spouse is employment-authorized incident to status, so she may take a job at a dental practice without a separate work permit once admitted. Dental hygiene is licensed by state boards, and most require their own examination or accept specific credentials, so the licensing process, not immigration, determines when she can start. She should contact the receiving state's board before the move, ask about recognition of her Quebec qualification and the clinical examination, and budget the time. Her work authorization lasts only while both spouses hold valid status; if the technician's L-1B ends early, so does her permission to work. Her own citizenship is not tested for L-2.
The child: two years of derivative status and then a decision
A nineteen-year-old is admitted as an L-2 dependant, may attend school or college, and holds no work authorization. On the twenty-first birthday derivative eligibility ends, whatever the parent's status, so the family should plan now for what happens then. If the child will be studying, a change to F-1 student status before the birthday is the usual route, and the timing of the application matters. If the child hopes to work, a category of his own is needed and none follows automatically from the parent's L-1B. Do not assume that a child who arrived as a dependant can simply remain; the age rule is applied by date.
The principal: keep the family calendar tied to the L-1B calendar
The technician's L-1B is capped at five years in total, including any earlier L time, and the whole family's derivative status depends on his. Record his admission date and the petition validity, and set reminders for the extension well before expiry, because a lapse in his status ends the spouse's work authorization and the child's study status at the same moment. If the family intends to stay beyond five years, the employer would need to consider an immigrant petition long before the ceiling, since L-1B does not convert to anything on its own. Each family member should carry their own status documents when travelling, and Canadian-born family members should note that their Canadian citizenship is a fact that may later open TN, but only for them individually.
