Family permissions require individual status and documentation review. The business structure does not itself establish a spouse’s or child’s immigration rights.
Check the actual family status basis
Qualifying L spouses are employment authorized incident to status with appropriate documentation. Children gain no work permission solely through L dependent status. A branch relationship does not remove those individual distinctions.
Treat the household as its own workstream with its own list. Each dependent needs a passport valid for the intended period, evidence of the relationship such as a marriage certificate or a long-form birth certificate, and any change-of-name document that reconciles the records. Where a certificate is in neither English nor French, arrange the translation and certification early, since a missing translation is a common cause of delay that has nothing to do with the business case.
Hypothetical example: a landscape lighting design studio moves its founder to a United States operation, and the founder's spouse assumes their own work permission arrives with the principal's approval. That does not follow automatically. Qualifying L spouses are employment authorized incident to status with appropriate documentation, and that documentation has to exist for the spouse in particular.
Confirm what this means for the household's income before the move rather than after it. Where a dependent will travel separately or later, plan that entry on its own, since a family member arriving alone carries their own documents and answers their own questions at the border.
