A longer client project is not a longer authorized stay. The dependent category is for a qualifying spouse or unmarried child under 21; each person needs valid 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. If the spouse works in a regulated occupation, begin the state licensing process early, since employment authorization comes with the status but the right to practise does not. Proper L-2S spousal documentation supports work incident to status; L-2 children lack employment permission, and neither derives specialized-knowledge authority from the principal. Keep the spouse’s relationship and admission evidence beside the offer, and have any effect of the transaction on the principal’s case assessed independently of the buyer’s willingness to retain staff.
