Ask what records are missing in this particular file and which genuine current corporate decisions need documentation. Estimate that work separately from the applicable government fees and immigration preparation.
Budget for documentation work, not just filing fees
Separate retrieving existing records, accurately explaining gaps and documenting new decisions. Do not budget for creating purported historical evidence of events that never occurred. Check the current charges for the actual petitioner and procedure rather than assuming one standard filing total.
Government charges are listed in the USCIS fee schedule, Form G-1055, and include the petition fee, the fraud-prevention fee and, depending on the company's size and workforce, other statutory fees; premium processing is optional. The predictable surprise for a closely held group is the cost of tidying corporate records: issuing shares that were only ever agreed, recording transfers, preparing registers, obtaining certificates of good standing, and having accountants produce statements for entities that have never needed audited figures. Confirm current official charges without copying amounts from another employer, and define whether professional fees cover entity analysis, drafting, translations, later inquiries, extensions, or family filings.
