IN THIS GUIDE · Prepare a knowledge and employment timeline that includes recorded absences
Start with the L-1B eligibility and application overview
Keep the actual dates visible
Hypothetical example: an employee completed relevant projects before a period of leave and later resumed work. Record the actual employment, absence and work-location dates without changing them to fit a desired filing schedule. Have the applicable continuity and qualifying-period questions assessed individually.
Explain the knowledge acquired before and after the absence
Identify genuine learning and application at each relevant stage. Do not describe planned refresher training as already completed, or assume absence alone means the employee has lost all qualifying knowledge. Explain the current knowledge and its actual relevance to the proposed U.S. duties.
Separate knowledge evidence from the employment calculation
Special or advanced organizational knowledge and qualifying foreign employment are distinct requirements. A strong earlier project may explain knowledge without resolving a disputed period, while a documented employment relationship does not establish the actual knowledge by itself. Provide evidence for both.
Use relevant records and accurate explanations
Identify appropriate employment, leave, training and project records, with privacy handled appropriately. Do not invent work during an absence or omit dates because their significance is uncertain. The company relationship and applicable transfer process still require review alongside the actual history.
A confidentiality agreement labels information; it does not make knowledge specialized
Signing an agreement about information and holding specialized knowledge of it are separate facts, and only the second is at issue. Confidentiality clauses appear in nearly every employment contract, and what they establish is a restriction on disclosure: they say nothing about what the person actually knows, how that understanding was acquired, or whether it is special to this organization’s products, services, research, equipment, techniques or management. L-1B asks the second set of questions. Build the answer out of activity rather than paperwork — which systems the applicant designed, adapted or commissioned, which problems they were called in to solve, what internal method they apply that a capable outsider would need substantial time to acquire. Where an employer’s answer to what is specialized here amounts to the material being confidential, the file has an obligation well described and a qualification still unproven.
A staffing contract is not an intracompany transfer
Placing a person and transferring one look commercially similar and are treated differently. Where an L-1B employee would spend their time principally at the worksite of another company, further conditions apply, and the arrangement is examined to see whether the petitioning employer still controls and supervises the work or whether the person has effectively been supplied as labour to that other business. A services agreement whose deliverable is expressed in bodies, hours or day rates points toward the second reading; one whose deliverable is a defined outcome the employer remains answerable for points toward the first. Gather the contract governing the offsite work, the statement of work beneath it, and whatever shows who directs the person day to day — assignment instructions, reporting lines, who conducts performance reviews. Settle this before the placement starts, since a signed contract is harder to characterise differently than one still in draft.
