Not by itself. The published route runs through an online application and fee, USCIS instructions, supporting documents with Form I-140G, vetting, the gift when instructed, and an EB-1 or EB-2 determination subject to visa availability. Eligibility for permanent residence and admissibility still apply. Complexity mainly affects how much explanation the record demands.
Ask what an unexplained gap costs
Take the two or three weakest points in the financial story to a qualified attorney and ask directly what each one implies for the case. A missing year of statements is a different problem from an unexplained transfer from a party nobody can identify. Ranking the gaps turns an overwhelming reconciliation project into a short list of things that actually matter.
It also shows whether the effort is worth beginning at all. Two points belong beside that ranking of gaps. The payment runs from the applicant to the U.S.
government and purchases neither a classification nor relief from any ground of inadmissibility, so a well-documented financial history is necessary rather than sufficient. And a determination must still be made under EB-1 or EB-2, subject to visa availability, which means the applicant's own qualifications and record carry the substantive weight, and that assessment can be obtained in parallel with the financial reconciliation rather than after it. Doing both at once often shows which one is actually the constraint.
Hypothetical example: a household spends four months reconciling accounts across three countries before asking which category the principal's record could support, and the answer to the second question turns out to determine whether the first was worth beginning.
