No. The framework operates through the existing EB-1 and EB-2 immigrant classifications, and those classifications carry their own eligibility requirements. A processing fee and a gift do not create a general work permission that the underlying classifications do not themselves provide.
Payment does not replace the classification’s own test
The question to put to anyone promoting this is simple and specific: which classification is being used, and does the applicant meet its requirements. Hypothetical example: the owner of a Saint-Cyrille-de-Wendover millwork shop is told that once the fee and the gift are paid he can accept employment with any American company he likes, in any role; the official framework does not say that, and the classifications it runs on have their own criteria that a payment does not satisfy.
Before committing, ask for the specific basis in writing, check the monthly Visa Bulletin position for the category in question, and note that oversubscription in a category is not cured by paying more. It is also worth writing down what you would do if the application were refused after the fee had been paid, since that fee is nonrefundable, and confirming at what point the gift becomes payable relative to vetting.
