Budget for the things that keep the enterprise directed while you are away: a manager's salary, remote systems, bookkeeping, and travel itself. These are business costs and belong in the projections; immigration-preparation fees are separate and should be quoted separately. Government fees change, so confirm current amounts at each step rather than relying on an earlier figure.

Ask whether the capital you count as invested is genuinely committed and at risk rather than parked where you can withdraw it between trips. Borrowing is not prohibited, but a loan secured by the enterprise's own assets is treated differently from one secured against assets you would personally lose. Nobody can guarantee a return, an approval, or a processing time, so keep a reserve that survives a slower launch than planned.
Build an investment ledger that distinguishes money already spent, funds bound by enforceable nonrefundable obligations, working capital controlled by the enterprise, and merely forecast expenses. Substantiality is assessed proportionally against the total cost of buying or creating the enterprise: a modest sum can be substantial for a small service business and plainly insufficient for a manufacturing acquisition. Substantiality is judged by comparing the enterprise column with the total cost of the business, so the personal column never helps eligibility no matter how large it grows.
