Derivative spouse permission is different from an independent specialized-knowledge principal case. Qualifying L spouses may be employment-authorized incident to status with appropriate evidence.
Identify the actual status basis
An EAD is not universally required for qualifying L spouses. Children do not gain employment permission solely through dependent status. The dependent framework generally covers a spouse and unmarried children under 21; each person must obtain and maintain the appropriate status.
The one continuous year of qualifying employment abroad within the preceding three years, and the qualifying relationship between the organizations, must be established with the same kind of documentation any other L-1B case would need, regardless of the business's size or family ownership. Record each family member's intended work or study and the relevant age and status dates, and verify the spouse's current status documentation rather than assuming one universal rule applies to every household. Immigration derivative status turns on a legal marriage recognised where it took place, and a common-law or domestic partnership does not qualify, however long standing and however documented. Treat the difference in maximum period as a planning input rather than a technicality, since specialized-knowledge classification is usually limited to five years and managerial classification to seven.
