Compare like stages as well as people. An individual principal plus one eligible spouse has total published processing fees and gifts of US$2.03 million; four eligible people total US$4.06 million. If processing fees were already paid, a later gift-only instruction will be lower than those combined totals. Reconcile the payment history before treating the difference as an error.
Counting the people the case actually covers
Verify who is eligible for inclusion before calculating the wire. A child who is already 22 cannot simply be counted as under 21; any claimed age protection requires case-specific review. Follow the issued family instructions rather than assuming every relative files a separate Form I-140G.
The corporate-principal amount also differs from the individual-principal amount, so identify the route on the calculation. Recalculate from the people, not from the total. List each person the case actually covers, mark whether they are a legally married spouse or an unmarried child under 21, attach the document that establishes it, then apply the published per-person amounts and compare the result with the demand.
Hypothetical example: the director of a clinical trials unit receives a single figure for a household of four and cannot reconcile it, because two processing fees had already been paid at application and the instruction covers only the gift stage. Ask the issuing channel to itemise the demand by person and by stage. A total nobody can break down is a total nobody can check.
