No. On the official framework it operates through existing employment-based first and second preference immigrant classifications. Their eligibility requirements, admissibility rules and visa availability all continue to apply, so the payment does not by itself create a right to permanent residence.
Start at the classification, not at the payment
The most useful question Bertrand can ask is one the marketing around this subject rarely raises: which existing category would he actually be admitted under, and does he meet it. The official material describes successful applicants proceeding through the first and second employment-based preferences after vetting, which means the ordinary substantive requirements of those categories are unchanged. A contractor who has built a dredging business over thirty years may or may not fit them, and the answer turns on his individual record rather than on his willingness to pay.
Two further filters sit behind that. Admissibility is assessed on the usual grounds, and nothing about this route sets those aside. Visa availability depends on the demand in the relevant category, which no applicant controls.
Because these are the determinative questions, the sensible sequence is to have a licensed United States immigration attorney assess the underlying eligibility first, and only then to look at what the framework would cost.
