IN THIS GUIDE · Make a technical knowledge claim understandable to someone outside the company
Explain the knowledge standard and the qualifying transfer
The standard concerns special knowledge of the organization’s products, services, research, equipment, techniques, management or other interests and their application in international markets, or advanced knowledge of its processes and procedures. The evidence must connect that knowledge to the proposed work; proprietary technology is not a universal prerequisite. A qualifying corporate relationship, doing business and the generally required continuous year of full-time qualifying foreign employment within the relevant three-year period also need assessment. A new office requires sufficient premises and has an initial approval maximum of one year. The ordinary qualifying foreign year may be managerial, executive or specialized-knowledge employment; the U.S. role must meet the requested classification. The group must continue regular, systematic business in the United States and at least one other country. A U.S. organization doing business for less than one year is a new office; show financial ability to compensate the employee and commence business as well as sufficient premises. An owner or major stockholder must also show temporary U.S. services and a subsequent foreign assignment.
Choose a concrete knowledge example
Describe a task the employee has actually completed: diagnosing an internal process, configuring an organization-specific workflow or training colleagues on a complex method. Explain the company context in plain language before using technical abbreviations. General technical ability and the particular knowledge claimed should be distinguishable to a reader who has never worked for the business.
Show how the employee acquired it
Connect the account to training, assignments or other available records. Identify the dates and the people who can verify the work. A long service history may provide context but does not explain the knowledge on its own. Avoid presenting a newly written narrative as if it were a contemporaneous record of training that was never documented.
Connect the example to the U.S. assignment
Explain what the receiving operation needs the employee to do and why the claimed knowledge is relevant. If work occurs at a customer site, disclose the actual supervision and placement arrangement for assessment. Do not hide an inconvenient fact by describing every location as a company office. Changes to the assignment should be reviewed against the case that was actually prepared. If primarily stationed at an unaffiliated worksite, the employee cannot be principally controlled and supervised by that employer, nor placed essentially as labour for hire rather than in connection with the petitioner’s specialized-knowledge product or service.
Control disclosure without losing the evidence
Have an authorized business contact decide what may be shared, then ask the reviewer whether any proposed redactions leave the claim understandable. Label exhibits by the facts they support. The process should protect information while retaining credible evidence; substituting an invented customer story is not an appropriate way to handle confidentiality.
