IN THIS GUIDE · Sequence a geomatics firm's transfer of its lidar-classification specialist
Start with the L-1B eligibility and application overview
Before drafting, inventory the knowledge
Hypothetical example: the specialist designed the firm's classification rule sets, the quality-control scripts that flag misclassified points and the calibration routine for the firm's particular sensor configuration. List each item and pair it with an internal document: a version-controlled script, a procedure manual, a training deck. Then list, separately, the general skills any lidar analyst has, such as familiarity with commercial processing software; those go in the resume but not in the specialized-knowledge argument. Build a knowledge inventory with concrete examples: internal configurations, unpublished troubleshooting history, controlled test results, and the consequences if the knowledge were unavailable. Avoid claiming secrecy where manuals or public training say otherwise.
Then establish how few people hold it
Ask the firm's technical lead for a written statement of how many staff can run the full workflow unaided, and how long it took the specialist to build the knowledge. A knowledge held by two people in a firm of forty, documented in internal manuals, is specialized; a knowledge held by every analyst after a week's training is not. Be accurate, because the affiliate will need to explain why it cannot simply hire an American analyst. Identify who else can perform each task, how long they needed to learn it, and which company records support that answer. The point is comparative value, not simply that the employee is talented.
Next, settle the corporate and employment facts
Confirm that the U.S. affiliate is related to the Canadian firm through common ownership shown in registers and a chart, that both are operating, and that the specialist has one continuous year of employment in the Canadian firm within the last three years, during which the knowledge was gained. Payroll records and the ownership chart settle these points and should be in the file before the specialized-knowledge narrative is written. Reconcile payroll, organizational charts, incorporation records, and contracts before describing the assignment. A clear chronology is particularly important where the corporate relationship changed after the worker began abroad.
Finally, structure any client-site work correctly
If the specialist will spend time at a state transportation agency's office, the services agreement must show that the affiliate assigns and supervises the work and delivers a product, not that the agency directs the specialist day to day. Placement that amounts to supplying labour to be managed by the client does not qualify. Only after these steps should Form I-129 be drafted and filed by the U.S. affiliate. For a client location, separate supervision by the petitioning company from ordinary coordination with the customer. The packet should identify deliverables and preserve the agreement that gives the petitioner meaningful control.
