The same categories: payroll and employment records, corporate formation and ownership documents, and evidence of actual business operations. Smaller or family-run businesses sometimes have to reconstruct these records rather than pull them from an existing HR system.
Reconstruct records carefully rather than estimating them
Where formal payroll records are incomplete, gather bank records, tax filings, or other contemporaneous evidence that supports the employment history. Avoid creating a document after the fact that presents an estimate as an original record.
An intracompany petition requires a qualifying relationship between the foreign employer and the American entity, as parent, branch, subsidiary or affiliate, evidenced by share registers, purchase agreements and corporate resolutions rather than by an organigram somebody drew. For a purchase of an existing U.S. dealership that means the signed and closed share or membership purchase agreement, the updated ownership ledger, a chart showing the percentage held by the Canadian parent, and the U.S. entity's state registration and tax identification. Gather the committee charter and minutes, but add organization charts, job descriptions, reporting lines, delegated assignments, budget authority, examples of recommendations and records showing who performed the underlying analysis.
