IN THIS GUIDE · Explain the special or advanced company knowledge a Lac-Beauport specialist will use in the U.S. assignment
Start with the L-1B eligibility and application overview
Sequence the file from the process outward
Hypothetical example: a Lac-Beauport quality-assurance lead at a medical-device manufacturer designed the company's sterilization validation protocol and is asked to install it at a new U.S. plant. Begin with the protocol itself: when it was written, by whom, what it replaced and where it is used. Then document the applicant's role in creating and applying it. Only afterwards describe the U.S. assignment, so that the knowledge is proven before the need for it is claimed.
Compare the applicant with the company's own workforce
USCIS asks whether the knowledge is different from that generally found in the industry and whether it is held by only some of the company's employees. A short statement of how many people in the group possess the knowledge, how long it takes to acquire, and what training would be required for a U.S. hire is more persuasive than adjectives. Avoid describing skills every qualified professional in the field would have.
Watch the offsite placement rule
If the transferee would work mainly at a client's site, the petition must show the employee will not be principally controlled and supervised by the client and that the placement involves the specialized knowledge rather than labour for hire. A Québec firm sending a specialist to a customer's U.S. facility should document who assigns tasks, who evaluates performance and who can end the placement.
Keep the corporate and family facts in view
The qualifying relationship and the doing-business requirement apply to L-1B exactly as to L-1A, so the ownership and operating records must be assembled. L-2 spouses are employment-authorized incident to status; children may study but not work and age out at 21. Time spent in L-1B counts toward the seven-year L-1A limit if the transferee is later promoted into a managerial role.
Use the applicable special or advanced knowledge standard
Primarily offsite work with an unaffiliated employer requires examination of actual control and labour-for-hire restrictions. Explain the special or advanced knowledge actually relied on and how the U.S. duties would use it, without assuming a credential or a familiar product name establishes the classification. The applicable standard does not universally require unique or secret knowledge, but a generic claim of familiarity is insufficient to explain the case. Third-party placement restrictions require careful review of supervision and whether the arrangement supplies the employer’s product or service requiring its specialized knowledge. The record should distinguish ordinary familiarity with a product from the employee's documented application of the company's particular methods.
