Preserve the historical entity names and dates, and gather the documents explaining each corporate change. Identify which organization actually employed the applicant during each relevant period rather than rewriting the record under the company's current name.
Make the chronology auditable
Link employment records to the effective corporate documents and flag any gap or conflicting date rather than smoothing it over. Distinguish a simple name change from a transfer to a different legal employer. A dated, sourced chronology lets a reviewer assess the qualifying period without guessing at facts a present-day summary might obscure.
Create a dated corporate-and-employment chronology before selecting exhibits. Pair each name change, amalgamation, asset transfer, or share transaction with the governing instrument, payroll records, tax material, and employment documents showing who employed the beneficiary. Then connect the resulting entities to a parent, branch, subsidiary, or affiliate relationship. L-1 generally requires one continuous year of full-time employment physically abroad during the relevant preceding three-year period; except under the special U.S. new-office rules, qualifying organizations must conduct business in the United States and another country throughout the stay. The avoidable mistake is relabelling every historical record with today’s corporate name, which conceals whether the employment and relationship truly continued.
Hypothetical example: an Ottawa medical-device distributor changed from a partnership to a corporation, then placed its sales assets under a new holding company before acquiring an American affiliate. Its operations director should gather partnership payroll, incorporation and transfer instruments, ownership ledgers, Canadian operating invoices, and the U.S. acquisition record. A concise timeline should identify every effective date and legal employer. Any interruption or entity mismatch belongs in the analysis, not beneath a simplified current organization chart.
