IN THIS GUIDE · Use the employee’s own foreign chronology rather than the company’s age
Start with the L-1B eligibility and application overview
Identify the relevant individual period
Hypothetical example: a company has operated for years while the applicant moved between duties and locations. Generally one continuous qualifying foreign year within the relevant preceding three years is required. Use actual dates rather than the organization’s founding date. Create a chronology for the individual that distinguishes a promotion, a move between countries and a change of legal employer. Ask which contemporaneous record supports each event. A company anniversary cannot demonstrate that this employee worked abroad throughout the necessary period. Where a reorganization changed names, preserve the former entity and explain its relationship instead of applying today’s name retrospectively. The chronology should also identify the actual foreign capacity; a present-day specialist title is not proof of duties performed in an earlier year.
Explain the actual knowledge and assignment
The standard covers special knowledge of the organization’s products, services, research, equipment, techniques, management or other interests and their application in international markets, or advanced knowledge or expertise in its processes and procedures. The standard is not universally limited to secret, proprietary or unique information. A long tenure alone does not establish the knowledge.
Preserve qualifying organizations and work locations
Show the actual corporate relationship and continuing operations in the United States and abroad. U.S. days do not count toward the foreign year, and a trip should not automatically be treated as breaking continuity. The timeline needs individual assessment.
Assess actual placement conditions
For work principally at an unaffiliated employer’s site, L-1B is unavailable if that employer principally controls and supervises the worker, or if the arrangement is essentially labor for hire rather than a placement connected with the petitioner’s product or service requiring specialized knowledge. A valid foreign chronology does not replace the placement review.
Complete the foreign-employment and new-office assessment
The qualifying foreign employment generally must be one continuous full-time year within the relevant preceding three years. Its capacity may be managerial, executive or specialized knowledge under the ordinary L rule; the proposed U.S. role has its own category test. Brief U.S. trips do not necessarily interrupt continuity, but U.S. days do not count toward the foreign year. The qualifying group must provide goods or services regularly, systematically and continuously in the United States and at least one other country throughout the relevant stay; registration alone is insufficient. A U.S. organization doing business for less than one year is a new office. L-1B then requires sufficient premises and financial ability to pay the employee and begin business; initial approval is limited to one year.
Advanced knowledge of internal procedures is a recognized basis
Where the employee will work primarily at a third party's premises, two additional conditions apply: the placement must not amount to labour for hire, and the petitioning employer rather than the site owner must retain control and supervision of the work. Set out the quality and documentation system in plain language: the internal procedures for task cards, the release process, the audit trail the organization maintains beyond regulatory minimums, and the internal training program. For L-1B preparation, distinguish general teaching or facilitation skill from relevant special or advanced organizational knowledge. Any principal offsite placement must not be labour for hire and must remain controlled by the petitioner. Prepare a knowledge map connecting the product or process, the applicant's developed expertise, its application, and the evidence source. Training records, internal manuals and comparisons with similarly employed workers may help, but the knowledge need not be proprietary or unique, and the petitioner does not have to prove that it is unavailable in the U.S. labour market.
