A company’s appointment resolution establishes a corporate action. It does not admit the officer’s spouse or child to the United States. Eligible L spouses may work incident to valid status with suitable evidence, while dependent children lack that spousal work benefit.
Do not use a board resolution as a family-status document
Prepare the corporate resolution for the principal’s role assessment and the actual relationship and admission records for relatives. If the board also names the spouse as an officer, disclose the proposed duties rather than treating that second appointment as authorization. L dependent eligibility is limited to a qualifying spouse or unmarried child under 21. The company can decide its appointments; the immigration process determines the status on which work depends.
A spouse's employer, a school, and a landlord will each want an answer sooner than the case can give one, and a household that has agreed its own fallback positions in advance answers those questions calmly rather than under pressure.
