No. Direction and qualifying investment are distinct conditions. Explain actual lawful capital, risk and commitment rather than treating authority as a substitute for money invested.
Keep the account complete
There is no universal fixed minimum, but substantiality still needs assessment against the actual enterprise. Separate private fees and unrestricted reserves from qualifying capital.
Enough to show substantial, irrevocable commitment relative to the total start-up budget, ideally most of it, plus the consular visa fee, any reciprocity fee, and professional and translation costs outside the investment. Prepare a post-closing cash schedule that separates purchase consideration, inventory, lease deposits, payroll reserve, legal fees, immigration costs and money still under the investor's control. For each investment item, retain bank records, purchase agreements, invoices, escrow terms, and proof that the applicant bears the risk of loss; exclude unsupported future receipts from the capital total. Substantiality is proportional to the total cost of purchasing or establishing this particular business, so a drainage installation company with trucks, trenchers and a crew is measured against its own acquisition cost rather than against any general figure. Ask your immigration reviewer for an itemized scope covering the eligibility assessment, the funds trace, dependent assistance, and responses to later requests, so no single price hides the work.
