IN THIS GUIDE · Specialist transfers after a corporate acquisition
Start with the L-1B eligibility and application overview
Identify the legal entities after closing
Map the foreign employer and U.S. petitioner, including ownership and control following the transaction. A purchase announcement or shared branding does not establish the qualifying relationship. Explain whether the transaction involved shares, assets or a different arrangement, and obtain the records needed to evaluate its actual legal effect.
Trace the employee’s history through the change
Record employing entities, transfer dates and duties before and after the acquisition. Do not assume all earlier service automatically qualifies merely because the employee remained at the same desk. Corporate succession and employment-history questions need fact-specific review. Preserve payroll and contracts from both sides of the transaction where available.
Explain where the knowledge now belongs
Describe the acquired products or processes and how they fit within the petitioning organisation. The employee may retain valuable knowledge, but the case must connect that knowledge to the current qualifying business and U.S. duties. Distinguish integration work from ordinary familiarity with the former employer’s customers or systems.
Replace obsolete evidence
Update assignment letters, ownership diagrams and business records after closing. If the transaction occurs during a pending or approved case, assess its immigration effect before relying on the old filing. A change in corporate identity can matter even when the project and employee are unchanged. Keep a clear transaction chronology with supporting documents.
Order the post-closing questions
After a transaction, three questions must be answered in sequence, and answering them out of order is the usual cause of wasted preparation. First, what did the transaction actually do in law: a share purchase, an asset purchase or some other arrangement, and which entities exist afterwards. Second, does a qualifying relationship of parent, branch, subsidiary or affiliate connect the foreign employer to the U.S. petitioner under that post-closing structure. Third, does the employee service history still supply one continuous year of qualifying employment abroad within the preceding three years, given the entities that employed the person before and after closing. The third question is the one an asset purchase most often disturbs, because the employing entity can change while the desk, the product and the manager do not. Only when all three are settled is it worth describing the specialized knowledge itself and the proposed U.S. duties, and planning against the five-year maximum that applies to L-1B.
Hypothetical example: an integration assignment after an asset purchase
Hypothetical example: a Canadian company supplying refrigerated-transport software is acquired by a U.S. group, and a specialist who built its temperature-monitoring module is proposed for a U.S. integration role. Sequence the file this way. Establish first whether the buyer acquired the shares of the Canadian company or only its assets, since that single fact determines whether the specialist earlier employment continued with the same legal employer or moved to a new one. Establish next which entity now employs the specialist abroad and whether it is related to the U.S. petitioner. Then describe the knowledge: what the module does, why the petitioning organisation needs someone who knows it, and how that differs from general familiarity with the former employer customers. Where the specialist will work at a third party site, confirm at this stage that the petitioner will continue to control the work rather than supplying labour for hire, because that condition shapes the evidence rather than being added to it afterwards.
