IN THIS GUIDE · A regulatory specialist whose qualifying year abroad was interrupted by a secondment
Start with the L-1B eligibility and application overview
Test the qualifying year against the actual employment record
Continuity is a question about the employment relationship, not about the desk she sat at. Establish who employed her during the secondment, who paid her, whose payroll she appeared on and whether the secondment was to a related entity or an unrelated partner. Pull the employment agreement, the secondment letter and the payroll registers for the full three-year window, then count the qualifying months rather than assuming the calendar year is intact.
Separate the company's knowledge from the profession's knowledge
Regulatory affairs is a recognised discipline with published rules that anyone in the field can learn. That part is not specialized knowledge. What can be specialized is her command of this company's own dossiers: the internal validation protocols, the stability data structure, the deviation history behind each submission and the undocumented reasons particular claims were worded as they were. List those items concretely, and be honest about which of them a competent regulatory professional could pick up elsewhere.
Say how many colleagues could do the same job
A file that calls the knowledge unique while eleven colleagues hold it invites exactly the wrong question. State the actual number of employees who have worked on the same dossiers, explain what distinguishes her from them, and describe how the knowledge was acquired — years on the submissions, authorship of the internal protocols, training she delivered to others. A modest, accurate claim survives scrutiny better than an inflated one.
Keep the work under the petitioner's direction
If part of the assignment involves working at a contract manufacturer's site, the arrangement must not amount to supplying a worker for that company to manage. The petitioning employer assigns her tasks, sets her priorities, reviews her performance and pays her; the third party receives a deliverable under a services agreement. Draft the agreement that way before filing, because a contract that reads like staffing is difficult to explain afterwards.
Sort general skill from company-specific knowledge
For L-1B preparation, distinguish general teaching or facilitation skill from relevant special or advanced organizational knowledge. New-office cases require evidence that the US operation can support the specialized-knowledge position within one year, not just an assertion that the employee is valuable. Familiarity with many systems does not automatically establish the special or advanced knowledge standard, and the other transfer requirements still need evidence. Identify who controls and supervises the work and why the petitioner-specific knowledge is needed; merely naming a proprietary system does not answer those questions. The classification concerns knowledge of the organisation's own products, services, and techniques, or an advanced level of knowledge of its processes, and length of service alone establishes neither.
