IN THIS GUIDE · Build the L-1B analysis independently of a previous professional classification
Start with the L-1B eligibility and application overview
Identify what the earlier decision actually covered
Hypothetical example: the applicant previously held professional work status for a different assignment and now proposes a company-specific implementation role. Provide the earlier records with their actual employer, dates and duties. Do not treat approval under another category as a determination that the L-1B standard is met.
Explain the knowledge required for the new duties
Describe the special or advanced organizational knowledge, how the applicant acquired it and what the U.S. assignment would require. General professional qualifications may provide context but do not replace this explanation. The role must be assessed on its actual work rather than its similarity to an earlier title. An L-1B stay is capped at five years, so the assignment plan should identify time already used in L status before projecting later phases. Hypothetical example: a maker of theatre-rigging control systems plans to send the technician who devised its fault-isolation sequence to train the U.S. support group. Version histories, training materials, prior project records, and the U.S. duty list help show knowledge of the company's own process rather than broad electronics skill. The decision is whether the stated assignment actually needs that special or advanced organizational knowledge. A role outline should identify the proprietary steps without disclosing every confidential detail, and it should correspond with the records supplied.
Prepare the full employment and travel chronology
Identify foreign and U.S. work, employers, status periods and relevant changes. Have the qualifying foreign employment and applicable lookback assessed individually. Do not count U.S. work as foreign employment or assume the effect of prior U.S. status can be determined from the approval notice alone.
Coordinate the transition before changing work
Have the appropriate filing, admission or status process reviewed for the actual circumstances. A pending plan to seek L classification does not itself authorize new employment. Identify which work is currently permitted and what must occur before the applicant relies on a different classification.
Name the company-specific thing the employee knows
The L-1B definition includes special knowledge of the organization’s product or other interests and their application in international markets, or advanced knowledge of its processes and procedures. If the employee works primarily at an unaffiliated client site, the petitioner must control the work and the placement must not be labour-for-hire. A US new office doing business for less than a year needs sufficient premises and financial ability to pay the employee and commence business; its initial approval is limited to one year. Written evidence answers both: a services agreement describing deliverables rather than headcount, a reporting line back into the petitioner, and a statement of who directs, evaluates and may reassign the employee. A first review should ask which record proves the employee learned and applied the company-specific method, not merely attended a course. For third-party work, agreements, supervision practices, and control over the employee’s daily tasks may determine whether the placement is workable.
