No. Only an eligible spouse and unmarried children under 21 may seek L-2 status as dependents of the principal applicant; other relatives, including business partners or extended family, need their own independent basis.
Confirm who is actually a qualifying dependent
Review the relationship documentation for the specific spouse and children involved, and do not assume that other family members connected to the business gain any status through this filing. A qualifying L-2 spouse may work incident to valid status with appropriate evidence; L-2 children may study but cannot work on that status alone. The principal’s approval does not grant relatives their own status.
Since the policy change recognizing L-2 spouses as employment-authorized incident to status, a spouse admitted in L-2 does not need a separate employment authorization document to begin work, provided the admission record carries the spouse annotation that employers accept for verification. The permission comes from the status itself, so the spouse is not tied to the transferring company, to a particular employer or to a particular occupation, and does not depend on anyone's goodwill to keep working.
