IN THIS GUIDE · Document knowledge that belongs to the company
Start with the L-1B eligibility and application overview
Identify the proprietary thing by name
The claimed knowledge must be identified specifically, but it need not concern a proprietary tool or something the company alone created. It may be special knowledge of the organisation's products, services, research, equipment, techniques, management or other interests and their international application, or advanced knowledge of its processes and procedures. General industry expertise alone does not establish the category. The file should explain what the beneficiary knows, how it is special or advanced, how it was obtained and why the proposed duties require it; proprietary material can support that explanation without becoming a mandatory element.
Trace how the beneficiary acquired it
How the beneficiary acquired and applied the asserted organisation-specific knowledge is relevant evidence. Internal training curricula, authored procedures, revision histories, project records and company certifications may all help. Evidence about how many other employees hold the capability can also be probative, but the law does not impose a fixed scarcity or uniqueness threshold. The record should use dates and named documents to establish special or advanced knowledge without saying the knowledge must belong exclusively to the organisation.
Show the petitioner still controls the work offsite
Placement at a client site is permitted, but the arrangement must not be essentially labour for hire and the petitioner must retain control of the beneficiary's work. The deciding documents are the service agreement and the supervisory structure. The agreement should show the client purchasing a defined service or deliverable from the petitioner; the structure should identify a named supervisor within the petitioner who directs the work and carries responsibility for it. Where the client sets the technician's tasks and hours, the paperwork will not save the characterisation.
Track the five-year ceiling against the programme
L-1B is limited to five years in total, and prior time in L status counts towards it. A capability-transfer programme expected to run in phases should be planned against that ceiling from the beginning, with a record of time already used. Where the role would change into directing a function and supervising staff, that is a different classification with different evidence and a different limit, assessed on its own facts. Deciding in advance which phases require this individual, and which can be handled by trained local staff, keeps the plan inside the limit.
