IN THIS GUIDE · Preparing several specialized-knowledge transfers at once without recycling one shared support letter
Start with the L-1B eligibility and application overview
Split the shared material from the individual claim
Two kinds of evidence go into these files. The corporate material — the qualifying relationship between the entities, the ongoing international business, ownership structure, and the receiving operation's description — is genuinely shared and should be assembled once, carefully, and reused. Everything about the individual is not: the duties proposed for that person, the employment chronology abroad, and the specific knowledge being claimed. Mixing the two produces a set of files where each one reads like a copy. Assign one owner to the shared corporate exhibits and a different owner to each individual file, and say so on the first day. The corporate material covering the qualifying relationship, the ongoing international business, ownership structure, and the receiving operation is genuinely common. Everything about the individual is not, and mixing the two produces a set of files that each read like a copy.
Interview every proposed transferee on their own
Group briefings save time and flatten the record. Sit with each person and ask what they work on, which internal procedures they apply, what they would be called about at night, and who else in the organization could do it. The answers will differ in kind, not only in wording, and those differences are the point. Someone who cannot describe the organization's own methods in their own words has a weaker file, and knowing that early is useful. Interview each proposed transferee alone and record the answers as given rather than summarising them. Ask what they work on, which internal procedures they apply, what they would be called about at night, and who else in the organisation could do it. The answers differ in kind rather than only in wording, and those differences are precisely what the individual files need.
Expect the group to be uneven
Assess each person without predicting that a particular number must qualify or fail. One file may have clear examples while another needs older project records or a clearer account of the proposed work. Generic competence alone is not the specialized-knowledge showing. Where a person’s evidence is weak, discuss the facts with counsel before choosing a different assignment, another route or a later timetable. Do not invent distinctions merely to make the team look varied. Expect an uneven group and plan for it rather than resisting it. One file may have clear examples while another needs older project records or a clearer account of the proposed work, and generic competence alone is not the specialized-knowledge showing.
Sequence the group rather than filing it as a block
Filing everyone at once concentrates the workload, the spending, and the risk. Consider whether the operation genuinely needs all of them on the same date, or whether the strongest one or two should go first while the remaining records are built. A first outcome can also teach the business what its evidence looks like from the outside. Keep one owner for the shared corporate exhibits so later files do not drift from earlier ones. Hypothetical example: four engineers from the same platform team are proposed for transfer in the same quarter. Filing everyone at once concentrates the workload, the spending, and the risk, so ask whether the operation genuinely needs all four on the same date or whether the strongest one or two should go first. A first outcome also teaches the business what its evidence looks like from the outside.
