Describe it accurately as a current explanation and support its factual statements with genuine records.
Do not recreate historical proof
A later summary should not be backdated or presented as work produced during an earlier project. Explain its sources and limitations.
Contemporaneous internal records: configuration and revision histories, design documents, authored training material, project files, adaptation records for equipment, and any registered intellectual property. Redacted internal documentation, training and certification records, project summaries naming the employee's role, and a letter explaining the process in enough detail to be understood. Source repositories with commit history, internal design notes, change records and support tickets showing who resolves what are contemporaneous and persuasive. Gather dated internal manuals, controlled revisions, training records, project assignments, supervisor declarations grounded in examples, and work products that can be disclosed lawfully. Collect ownership and affiliate records, foreign payroll and employment evidence, training materials, product documents, project assignments, and a detailed US role description. Training records and course outlines answer the first; project files, sign-offs and correspondence answer the second; an internal certification, an escalation list or a role definition answers the third.
