Start with the L-1B eligibility and application overview
Describe company knowledge concretely
The standard may involve special knowledge of company products or interests and international application, or advanced knowledge of processes and procedures. Knowledge need not be unique or proprietary. Explain the employee’s practical capability rather than treating certification as automatic qualification.
Address employment and assignment conditions
Prove a qualifying relationship, continuous qualifying foreign employment year within the relevant three-year period and continuing US and foreign business. Describe supervision and primary unaffiliated offsite work under the control and labour-for-hire restrictions. New offices require sufficient premises and financial ability to pay and commence business; initial approval is limited to one year. The qualifying relationship must be a parent, branch, subsidiary or affiliate, both entities must remain active, and L-1B status is capped at five years.
Employment days and actual business activity
US days do not count toward the qualifying foreign employment year; a trip does not automatically break continuity. The qualifying organization must provide goods or services regularly, systematically and continuously in the United States and at least one other country. New-office treatment concerns actual US doing business for less than one year, rather than incorporation alone.
Hypothetical example: a CNC programmer with a vendor certificate
Hypothetical example: a View Royal architectural-millwork manufacturer wants to transfer its CNC programmer to a newly acquired US subsidiary that will produce the same custom casework line. He holds the machine vendor's advanced programming certificate, which thousands of shops' staff also hold. Leading with that certificate invites the response that the knowledge is general to the industry. What is actually special is the company's own parametric library of joinery components, its nesting rules that reduce veneer waste, and the finishing sequence it developed for a particular hardwood, none of which the vendor teaches. The petition should show that he wrote most of that library, that his revisions are logged with dates in the company's version history, that two of nine production staff can modify it and only he can rebuild it for a new machine model, and that the US subsidiary's first-year orders depend on reproducing exactly those components. The certificate belongs in the file as context; the version history and training records carry the claim.
Sequence the transfer and respect the limits
Confirm first that the acquired US company is a qualifying subsidiary and that both entities will keep operating, then that the programmer has one continuous year with the Canadian company in the last three, excluding any days spent working in the United States. Export the version history and training records before they are overwritten by a system migration. Describe US duties and who supervises them, and if he will commission machines at a customer's plant, keep him under the petitioner's control and avoid a labour-for-hire arrangement. L-1B time is limited to five years in total; an L-2 spouse is employment-authorized incident to status, and L-2 children are not.
