Records that already exist are worth more than statements written for the filing. Design documentation naming him, version histories, internal training material he authored, service reports from installations he led, and the employment records establishing his continuous qualifying year abroad form the core of a defensible file.
Assemble the exhibits before anybody writes the argument
A common sequence goes wrong from the start: counsel drafts a strong description of specialized knowledge, then asks what can be attached to support it. Reversing the order produces a narrower but far more durable petition. Useful exhibits include the original design specifications with authorship attributed, revision logs showing which changes he made and when, commissioning reports from terminals where his system was installed, and any customer acceptance documents referring to his role.
Internal course materials or procedures he wrote demonstrate advanced knowledge of the organization's processes better than an assertion ever will. Alongside that sits the employment evidence: payroll records and dated letters establishing one continuous year with the qualifying organization within the three years before filing, plus the corporate records proving the relationship between the Thunder Bay company and the American affiliate.
