IN THIS GUIDE · The document that decides whether a localization analyst's knowledge is the company's
Start with the L-1B eligibility and application overview
The internal documentation is the deciding exhibit
USCIS evaluates specialized knowledge under the totality of the circumstances; proprietary or unique knowledge can support a case but is not required. Relevant evidence can show what the process is, how the employee gained the knowledge, how her knowledge compares with that of others in the organization and whether it is readily imparted. For a process-based claim, the company's written procedure can be persuasive: the workflow manual, scoring rules, version history showing internal development and access or training records showing who uses it. If the analyst's name appears in its revision history or as its trainer, that supports both the nature of the process and her advanced knowledge. If the procedure exists only in her head, detailed, specific and credible company statements and other records may still prove the case, but the claimed knowledge must be described concretely.
Documents that do not decide it, and are often relied on anyway
Generic praise from a manager, a list of certifications in commercial translation tools, a description of the industry's general practice and a bare statement that she is the best analyst on the team do not by themselves establish specialized knowledge. A detailed, specific and credible statement from the petitioner can be persuasive evidence, but it must explain the knowledge rather than merely praise the employee. Certifications in tools available to competitors usually show general skill unless the company explains how they connect to its own process. Salary comparisons and job advertisements may provide context, but they cannot substitute for a detailed description of the process and the employee's advanced knowledge. Put the process documentation, training records, client-onboarding reports and a specific petitioner statement at the front.
Confirm the year, the relationship and the assignment structure
She needs one continuous year of employment with the Canadian company in the three years before filing, which three years on payroll satisfies; provide the records. The Canadian company and the U.S. affiliate must be linked as parent, subsidiary, branch or affiliate and both must be active. The U.S. assignment must involve applying the specialized knowledge — setting up and running the workflow for the American account — and if she will spend time at the client's premises, the petition must show that the affiliate, not the client, controls and supervises her work and that she is not simply supplied as labour. The initial period for an established office is up to three years, the L-1B ceiling is five, and her spouse would be employment-authorized in L-2 status while children may study but not work.
