The expenditure and actual capital contributed require their own treatment. A conversion loss is not automatically money invested in the enterprise.
Budget the final required contribution
Separate exchange costs, government and professional charges from qualifying capital. Confirm the applicable amount for the filing rather than assuming a historic foreign-currency balance remains sufficient.
Government filing fees for each stage, published in the USCIS fee schedule; project administration or subscription fees where a pooled investment is used; legal fees for the petition and the source-of-funds work; and the cost of documenting the funds themselves. Legal fees on this route are higher than on temporary categories because the source and path of funds file is genuinely large, and where the money comes through a succession there is often accounting work to reconstruct valuations and tax treatment. A direct investment generally has no regional-center administrative fee, but it may involve its own acquisition, legal, accounting and business-operating costs that a packaged regional-center offering would otherwise bundle. The professional work is substantial: source-of-funds documentation for a family with decades of agricultural history is a long engagement, and the later stage requires evidence that the investment was sustained and the jobs created. Financial diligence on the project, an independent review of the offering documents and cross-border tax advice are separate and should be obtained before the wire, since the immigration approval offers no protection for the capital itself.
