IN THIS GUIDE · A qualifying year served at the group's plant in a third country
Start with the L-1B eligibility and application overview
The year has to be abroad, continuous, and with the qualifying organization
The condition is one continuous year of employment with the qualifying organization outside the United States within the three years immediately preceding the petition, in a managerial, executive or specialized-knowledge capacity. Each element does work. Employment with a qualifying parent, branch, subsidiary or affiliate abroad can satisfy it, so Ilse's posting to the group's Mexican plant is not disqualifying merely because it was not in Canada. What has to be established is that the Mexican entity forms part of the same qualifying organization, which is a question about corporate ownership rather than about branding or shared systems. Build a dated employment ledger from payroll, tax and assignment records. It should show the employing entity, work location, leave and any U.S. periods for every month in the relevant window. This quickly reveals whether the required overseas service is complete and whether a corporate document is needed to connect a host payroll company to the qualifying group.
Continuity is where these cases actually fail
The word continuous is easy to skim past. An assignment interrupted by a period of employment with a different company, by a resignation and rehiring, or by a stretch of unpaid leave can break the year even where the person's overall relationship with the group never ended. Short business trips generally do not, but time spent working in the United States for the same group does not count toward the year abroad, although it may be recapturable against the maximum period of stay. Ilse should reconstruct the last three years month by month from payroll records rather than from memory, and check for gaps she has forgotten. Interruptions should be classified, not hidden. A documented vacation or a brief trip may be explained differently from a resignation, a long unpaid absence or employment with an unrelated firm. The review should obtain the underlying leave policy and assignment terms, because a later generic letter cannot reliably reconstruct why a gap appeared on the payroll record.
Which entity paid her, and under what arrangement
International assignments are administered in several ways: the home entity continues to pay and recharges the host, the host entity puts the employee on its own payroll, or a group service company employs her throughout. Each produces a different documentary record, and the petition has to describe the arrangement accurately. Where a secondment agreement exists it should be produced. Where payroll moved between entities, the ownership relationship between those entities becomes part of the evidence. None of these structures is fatal, but a petition that describes the relationship loosely invites questions that a precise account would have avoided. The petition should trace both the payment route and the supervision route. If one group company paid salary while another set work and evaluated performance, include the secondment or recharge records that explain that arrangement. This avoids a misleading shortcut in which the file names only one company even though the person was integrated into another part of the group.
The specialized-knowledge test remains the substantive question
Once the year is established, the case turns on whether Ilse's knowledge is special knowledge of the organization's products, processes or procedures and their application, or an advanced level of knowledge of its internal processes, rather than skill widely held across the industry. Paint-systems experience is common; experience with this group's particular coating specifications, defect-adjudication rules and line configurations may not be. The evidence should make that comparison explicitly. L-1B is limited to five years in total, both entities must be doing business, and a spouse in L-2 status is employment-authorized incident to status under current policy. If she is placed at a client site, the petitioner must retain control of her work and the arrangement must not be labour-for-hire. Specialized knowledge should be compared with the knowledge available in the U.S. labour market and within the group. Training manuals, access controls, product-release responsibilities and examples of problems the worker alone has resolved can make that comparison concrete. L-1B is subject to a five-year maximum period, so the business should also identify its long-term staffing plan rather than treat the transfer as open-ended.
