A residential address raises two separate issues: whether the company has sufficient premises for its actual new-office operation, and where the family will live. Do not assume that securing housing establishes the business requirement.
Keep relocation and business evidence distinct
Have counsel assess the proposed work arrangement and relevant occupancy facts. Separately prepare L-2 documents for an eligible spouse and unmarried children under 21. A spouse’s qualifying L-2 work authorization does not validate premises, and children in L-2 cannot work.
Family housing plans should account for the immigration schedule rather than treating a signed lease as authorization to move or begin U.S. work. Using the family's intended home as the company address mixes two evidence questions that are better kept apart, and it tends to weaken both.
The business needs to show premises appropriate to its operation; the household needs to arrange accommodation. Where a home address genuinely serves as the business's registered office while the operation is conducted elsewhere, explain that distinction rather than leaving it implicit. Where the business would actually be run from the home, the question becomes whether that is consistent with the operation described, and it may be for some businesses and plainly not for others.
Consider also the practical consequences: local rules may restrict business use of residential property, and a lease or a mortgage may contain relevant provisions. Keep the household's arrangements documented separately from the company's.
