Prepare a coherent account of the actual path and explain material movements rather than hide them.
Reconcile the chain with genuine records
Use the relevant statements and explanations for the funds actually contributed. USCIS requires full English translations with certification of accuracy and translator competence for foreign-language documents; consular instructions should be checked separately.
Make a ledger following contributed money through each intermediate account, with corresponding statements, wire advices, exchange records, and explanations for unusual deposits. Include complete certified English translations where required, preserving the original-language document and translator certification. Account closures or routine transfers should be explained, not hidden. Identify whether the structure calls for Form I-526E for a regional-center investment or Form I-526 in a direct case. Confirm US$1,050,000 as the general capital requirement; qualifying infrastructure projects or targeted employment areas use US$800,000, alongside a plan for ten full-time jobs. Conditional residence and the Form I-829 filing during the 90-day period immediately preceding its second anniversary mean records should remain organized beyond petition filing. The common failure is showing only the final wire, leaving lawful source and path unresolved.
Hypothetical example: A commercial electrician near Saint-Charles-de-Bourget routes business-sale proceeds from a notary trust account into a Canadian savings account, then through a currency provider before contribution. He indexes every statement and transfer to a one-page timeline, obtains translations for the relevant French records, and explains a returned test wire. Nothing is omitted merely because the last transfer is clear. Reviewers can trace one continuous chain without mistaking internal movements for new capital.
