Provide the changed assignment for assessment if it affects the duties, knowledge relied on or work arrangement. Do not assume the earlier strategy automatically covers it.
Describe the revised work
Identify which sessions, responsibilities or locations changed and what remains the same. Keep the start conditional on the appropriate immigration steps. A new course title should not conceal a materially different assignment.
Build the calendar from present facts: the worker’s qualifying foreign-employment dates, evidence-completion milestones, chosen petition procedure, requested assignment start and existing periods in L status. L-1B placement with an unaffiliated organization cannot be a labour-for-hire arrangement; the petitioner should retain control, and the work should principally involve the petitioner’s specialized knowledge rather than ordinary services directed by the customer. If internal training records, project histories, technical comparisons, and assignment documents already demonstrate the applicant’s special or advanced company knowledge, waiting may add delay without resolving a legal gap. If the assignment is genuinely tied to a commissioning window, say so in the petition as the business reason for the transfer; a specific operational purpose strengthens the knowledge claim rather than weakening it. L-1B eligibility still depends on the related organizations, the worker’s required continuous year of qualifying employment abroad inside the applicable three-year lookback, and special or advanced company knowledge used in the assignment.
