No. The spouse needs the appropriate individual status. Qualifying L spouses are employment authorized incident to status; the relevant status documentation must be checked.
Plan for separate evidence and dates
Include intended work, study and travel for each family member. Children do not gain work authorization solely through dependent status. Review age and status issues before using the corporate relocation timetable as the household’s complete plan. The dependent categories cover a qualifying spouse and unmarried children under 21. Check each person’s relationship, age and period of authorized stay rather than extending a permission from another household member.
Documentation practice still matters: employers completing employment eligibility verification will want to see the admission record, and it is sensible to carry the marriage certificate and the principal's approval notice. The permission belongs to a spouse in a legally recognised marriage; a partner who is not married to the principal is outside the derivative scheme altogether and needs an independent basis. Place the principal’s status end date beside the family calendar: L-1A has a general seven-year maximum, subject to regulatory exceptions and recapture rules.
