No. Dependants of L-1A and L-1B principals generally seek L-2 under the same rules. A qualifying L-2 spouse is authorized to work incident to status, but an L-2 child receives no employment authorization merely from being a dependant.
Review the household independently of the chosen L category
Choose the principal applicant's category based on the actual role, not a belief that one L subcategory gives the family different permissions. Record each dependent's citizenship, age and current status documentation, and confirm the spouse's employment authorization status rather than assuming it automatically exists. Assemble those records chronologically, identify their precise U.S.
use, and prepare a controlled explanation of confidential evidence. Verify each person’s admission record immediately after entry. For family matters, make the principal category decision independently of dependent plans, then record each person's age, status, and intended activity.
The family must decide whether a spouse's work plan needs separate documentation or a different timing sequence. Hypothetical example: A prosthetics-component manufacturer transfers an engineer whose spouse plans work; the family must check the spouse’s separate documentation instead of tying that plan to the L-1B label alone.
