No reliable timetable should be accepted from an intermediary. Vetting follows the processing fee, the gift follows successful vetting, and applicants then proceed through EB-1 or EB-2 subject to eligibility, admissibility and visa availability.
Payment is not the end of the process, and urgency is a sales tactic
The most useful question Solange can ask is what remains outstanding after she has paid. The answer is substantial: successful vetting is not a status, and the route continues through EB-1 or EB-2, each of which has its own eligibility requirements, admissibility screening and visa availability constraints that no payment removes. Any promised completion date should therefore be treated with suspicion, particularly when it is attached to a deadline that appears nowhere official.
Program terms have already been revised since announcement and can be revised again, which is a further reason to re-verify before paying rather than to hurry. If Solange feels rushed, that feeling is itself information; the official page will still be there tomorrow and a genuine process will not evaporate overnight.
