Government filing charges for the investor petition, the immigrant visa or adjustment stage and later Form I-829, all published in the USCIS fee schedule, Form G-1055. Beyond those sit legal fees, source-of-funds preparation, translations, and in a regional-centre case the project's own administrative charge.
Several of these are non-refundable whatever the outcome
The qualifying capital is the visible number, and it is the one people budget for. The surrounding costs are smaller but they are spent regardless of whether the case succeeds. Government charges apply at each stage and change periodically, so Form G-1055 is the only figure worth relying on.
Legal work in an EB-5 matter is substantial because the source-of-funds file is substantial; a complex business sale with intermediaries can take months of preparation. Translation and certification of French or other non-English documents is charged by volume and is easy to underestimate. Where a regional-centre project is used, there is normally an administrative or subscription fee payable to the project that is entirely separate from the investment, and it should be identified in writing before anything is signed.
Hélène should also weigh the cost of the capital being unavailable and at risk for years, which no schedule shows.
