Costs may include legal review of the corporate ownership and governance structure, drafting or revising documents to clarify supervision, and potentially renegotiating the offer's equity terms. This upfront review cost is generally worthwhile compared with the risk of proceeding with an arrangement that could be viewed as self-employment.
Treat structural review as necessary, not optional, spending
Ask for a specific review of the corporate documents and governance structure as part of the initial assessment, rather than treating the offer letter alone as sufficient. If restructuring is needed, budget for the time and any legal fees to revise ownership terms or clarify supervisory authority in writing. This spending addresses a real eligibility risk rather than adding unnecessary cost to the process.
Ask for the review to be scoped as a defined piece of work with a written output, since that is what makes it usable. A short opinion identifying who controls the entity, what the governance documents actually say, and whether the arrangement can honestly be described as employment is a document the business can act on and return to later. Where restructuring is recommended, the corporate legal work sits outside the immigration engagement and should be priced by whoever will do it.
Agreeing in advance who pays for that work avoids a stall at the point the answer is known and someone has to act on it.
