Read the effective scope and responsibilities alongside evidence of actual supervision and duties.
Check practice against the wording
A contract saying the employer retains control may not explain a different real arrangement. Do not hide material customer direction behind a standard clause.
Training records, permitted project descriptions, internal qualification documents and similar evidence can accurately explain the knowledge involved. Internal technical processes or client-sensitive material should be analysed from the actual proposal, not from an abbreviated label in an email or a planning spreadsheet. Beyond the usual corporate and employment records, the file needs the contract or statement of work, a written description of supervision arrangements, and material showing the method is the petitioner's own. Use genuine work examples, role evidence and relevant technical material with an understandable explanation. Supporting material may include authored analyses, configuration records, training histories, decision memoranda, and statements from people who can explain the contribution firsthand. Support the customer period with service contracts, purchase records, or access logs, and the employee period with payroll, tax, personnel, and internal assignment records. Gather the actual technical materials, document controls, training records, product history, organization charts and assignment plan. Remove obsolete material and explain confidential exhibits clearly enough for a reviewer to understand their significance.
