Explain which knowledge remains relevant and which new procedures the employee must learn. The earlier framework should not be presented as current without clarification.
Update the assignment’s actual knowledge requirements
A past example may still show learning or judgment, but connect it to the work now proposed. Review material changes before relying on the old description for the employee’s start. A revised internal review framework does not automatically strip earlier organizational knowledge of its value, but the petition should separate what still functions as company-specific process from what has since been retired or replaced.
Internal manuals, training slides and workflow diagrams predating the change can misstate current practice if attached without a note explaining what has since moved. Ask the employer to produce a short crosswalk showing which prior responsibilities map onto the redesigned framework and which duties are genuinely new, since a specialized-knowledge showing rests on the applicant's grasp of the organization's actual current processes rather than a version that no longer operates. Counsel should also confirm whether the redesign changed reporting lines, approval authority or the systems the applicant would use day to day, because any of those shifts can affect how the proposed U.S.
role is described. Treat the older framework as historical context supporting how the knowledge was gained, never as a live description of the assignment being filed.
