IN THIS GUIDE · Establishing the corporate relationship and knowledge continuity when the applicant's employer has been acquired
Start with the L-1B eligibility and application overview
Rebuild the corporate chain as it exists now
L classification depends on a qualifying relationship between the employer abroad and the receiving United States entity, and on both continuing to do business internationally. After an acquisition, that relationship may run through entities that did not exist, or did not connect, when the applicant was hired. Ask the corporate team for the current ownership diagram, the closing date, and the legal names of the entities that now employ the applicant and would receive them. Names on a payslip often lag behind the structure.
Trace the employment record through the change of ownership
The applicant generally needs one continuous year of qualifying employment abroad within the relevant preceding three-year period, and an acquisition can obscure whether that year sits with one employer or two. Collect employment letters, payroll records, and any continuity-of-service or transfer document issued at closing. Note whether the role, reporting line, or entity name changed on paper only. Whether service before the deal counts toward the qualifying period is a legal question, not an assumption to build a plan on.
Describe the knowledge as it functions today
Specialised knowledge concerns the company's products, services, research, equipment, techniques, or management and their application, or an advanced level of knowledge of the organisation's processes and procedures. After a deal, the applicant may hold knowledge of the acquired business that the combined organisation now depends on. Write that in operational terms: which systems, which customer configurations, which integration tasks nobody else has run. Avoid arguing that the person is irreplaceable, because uniqueness is not the standard.
Separate what an adviser organises from what counsel decides
An adviser can assemble the ownership diagram, the continuity records, the duty statement, and the integration plan into one reviewable package. Which entity should be named as petitioner, whether pre-closing service counts toward the qualifying year, and whether the proposed placement raises offsite supervision issues are matters for licensed United States immigration counsel. Agree what the reviewer will receive, what remains undecided, and which employer contact answers corporate questions, before anyone commits to a start date.
Write the chronology first and annotate the transaction into it
The temptation after an acquisition is to explain the corporate story first, because it is fresh and everyone involved has been living it. The more useful order is the opposite. Build the individual's employment chronology as a plain table — hire date, entity, role, location, classification, and any period spent working in the United States — and then annotate the transaction into it at the point it occurred, noting what changed on paper and what did not change in practice. That order matters because two requirements turn on dates rather than on narrative. The qualifying employment abroad is generally one continuous year within the relevant preceding three-year period, and an acquisition frequently produces artefacts that look like breaks: a contract novated weeks after closing, a new employee number, a short gap between one payroll system's last run and another's first, a transfer between group entities recorded as a leaver and a joiner. And L-1B stay is capped at five years in total, with time already held counting toward it. Both are answered from the table. Note as well what genuinely cannot be evidenced and say so, since an honest gap with a stated basis is more useful than a confident line with nothing behind it. Hypothetical example: a franchise-operations specialist's chronology shows a three-week paper gap that never existed in practice, documented at the front rather than left to be noticed.
