The draft franchise agreement, the franchise disclosure document, the fleet lease program terms, the proposed location lease, a written itemization of his own investment, and the fund-trace records. Send them as drafts so clauses harming the case can still be negotiated.
What to ask the franchisor for
Ask the franchisor for the current disclosure document, which sets out the fees, the estimated initial investment range and the obligations on both sides, and for the fleet program terms in full, since they determine what is and is not his capital. Ask for a written statement of which operating decisions the territory owner makes without approval, because that statement will support the direction argument and reveal any disagreement early. Ask whether the territory fee can be escrowed or the agreement made conditional on visa issuance, and get the answer in writing.
From his own side, prepare an itemized investment list excluding the fleet, the bank statements showing where the savings sit, and the records that explain their origin, such as the contracting business's distributions and tax filings. If the location lease is being negotiated, send the draft, because a signed lease is evidence of commitment and also a liability if the visa is refused. Assemble those before any narrative; the narrative should describe what the documents show.
