Start with the L-1B eligibility and application overview
Map each project to its actual employing entity
Create a chronology showing the legal employer, work location and project for the relevant period. Establish one continuous full-time qualifying foreign year within the relevant three years; US days are not included, although qualifying short visits do not automatically break continuity. Reconcile differing payroll and project names with authentic records. A shared brand does not prove the required qualifying relationship to the US organization.
Explain the knowledge without merging two companies’ work
Identify the individual’s actual contribution and how the US duties use it. The standard can be special knowledge of company products or other interests and international application, or advanced knowledge of company processes and procedures; uniqueness and proprietary ownership are not mandatory. Attribute each example to the correct organization and employee rather than claiming the entire group’s expertise as the applicant’s own.
Connect the US assignment to the entity that directs it
The qualifying group needs regular, systematic and continuous business in the US and another country. For a primary placement at an unaffiliated employer’s site, identify whether that employer principally controls and supervises the worker, which bars the placement. Also exclude essentially labour-for-hire arrangements rather than placements tied to the petitioner’s product or service requiring specialized knowledge specific to it. Internal billing alone does not answer these supervision and placement questions.
Verify the receiving operation’s actual age and capacity
Count actual US doing business rather than the age of a group brand. Below one year, new-office L-1B requires sufficient premises and financial ability to pay the worker and begin business, with initial approval limited to one year. Identify which entity supplies those resources. If the employer changes during preparation, preserve the effective dates and reassess the record instead of changing names on earlier documents.
Advanced knowledge of internal procedures is a recognized basis
Where an L-1B employee will be primarily stationed at the worksite of an employer other than the petitioner, two further conditions apply. The work has to remain controlled and supervised by the petitioning employer, and the arrangement must not amount to providing labour for hire to the site owner. Familiarity with a floor plan or ordinary warehouse experience is different from evidence of special or advanced organizational knowledge. L-1B does not universally require unique, secret or proprietary knowledge or a U.S. recruitment test. If the employee’s knowledge is genuinely of those things, the claim concerns the petitioner’s own equipment, techniques or procedures. Answering that means producing the services agreement and pointing at the clauses that keep direction with the petitioner: who assigns tasks, who reviews the work, who can remove the employee, who owns the deliverable, how the customer is billed. Identify the internal methods, product history, or cross-border process the employee learned, then show the decisions the U.S. team expects the employee to make with it. Dated training materials, controlled-procedure revisions, project assignments, escalation logs, and organizational charts can establish different points.
Industry certification is general skill, not specialized knowledge
The petition should identify a concrete product, service, technique, process or procedure of the organization, such as drying schedules developed for particular species and kiln configurations, a moisture-control protocol, a grading system or specialized software. Manufacturer training on a purchased controller, certification on a third-party platform, and industry qualifications are all valuable and none of them is the company's own knowledge. Skill that any experienced practitioner in the trade would hold does not reach that standard however valuable it is; conversely the knowledge need not be secret, patented, or held by only one person. Knowledge applied to the organisation's own products and procedures sits differently from the same skills sold as general consultancy to an unrelated customer, and a project that gradually reorients toward external clients can cross that line without a single decision that looks significant.
