Into corporate and accounting work, because that is what the whole plan depends on. Filing charges come at the end and are published in the current fee schedule.
Pay for the foundation first
The natural instinct is to engage on the petition and treat the corporate side as background, which inverts the dependency. Money spent early on having counsel document the ownership chain properly, and on having financial statements prepared to a standard an external reader will accept, protects everything downstream. Filing charges themselves should be confirmed against the current schedule when the petition is prepared, with premium processing treated as a separate decision. Between those two ends sit the costs that assume success: premises abroad, equipment relocation and the transferee's own move. Those belong last in the sequence precisely because they are the ones that cannot be recovered if a structural problem surfaces late.
The first budget should assign each expense to a decision: corporate-document review tests the relationship, accounting evidence tests active business, and relocation spending follows an approved plan. The current government schedule resolves filing charges; a lease proposal or mover quote resolves operational estimates. Do not combine those categories into one optimistic total. The decision is whether the business can fund the qualifying operation and the transfer even if timing changes. Hypothetical example: a solar-installation company delays shipping specialized tools until its accountant confirms that the receiving affiliate’s financial records support the proposed manager role.
