Review the actual facts, dates and scope of each description. Explain genuine changes or inaccuracies and prepare a truthful, supported account.
Resolve discrepancies rather than hiding them
Identify the appropriate records and people who can establish the duties. Do not silently rewrite earlier employment history to match a preferred immigration narrative. A credible explanation preserves what actually happened.
Ask whether the conflict is cosmetic or substantive before drafting any correction to a résumé or an employer letter. A résumé often compresses years of work into short bullet points, while an employer letter is written to satisfy the primarily managerial or executive standard that an L-1A petition requires, so the two documents can drift apart in emphasis without either one being false. Compare each disputed duty against payroll records, organizational charts and performance reviews to see whether the underlying role actually changed or only its description did.
Job titles and seniority language do not establish managerial or executive capacity by themselves, so a reconciled account should describe who reported to the position, which decisions it controlled and how much independent judgment it carried. Where the documents genuinely reflect different points in the same career, date each version and explain the transition instead of blending them into one narrative that never existed. Flag any duty that cannot be verified through a third source so a reviewer can address it directly rather than discovering it later.
