Authority from the business and immigration permission are separate. A qualifying L spouse may work incident to valid dependent status with appropriate evidence, such as the applicable spouse-specific I-94.
Check the person’s status and actual activity
The principal’s petition approval does not grant the spouse status automatically. Identify what the spouse would do and when. Qualifying unmarried children under 21 may accompany in L dependent status, but do not receive the employment authorization available to qualifying spouses.
An L-2 spouse is employment-authorized incident to status and may work for any employer, including the same company, once admitted with the correct annotation. A proposed family role should remain identified as proposed, with actual permission assessed for any US work. Working for a foreign team does not itself settle permission to perform the work from the United States. The principal’s L-1A petition must rest on a qualifying related organization, one continuous foreign year within the preceding three, and primarily managerial or executive US duties. Signing authority is a corporate governance question, decided by bylaws or a board resolution, and it is separate from whatever the spouse's status permits. Confirm each before relying on it, since holding a title or a company role does not by itself answer whether a particular signature is authorized. Ask the company's counsel to document the actual signing authority in writing rather than assuming it exists because the spouse is present and available. Keep that authorization separate from the household's immigration paperwork, since those records answer different questions.
