Review the employee’s actual knowledge of the version used in the proposed US work.
Explain continuity and any new learning
Some expertise may remain applicable while new steps require additional learning. Do not claim completed knowledge of a revised method merely because the employee knew the earlier procedure.
Compare the old and new procedures line by line, then classify the employee’s knowledge as retained, changed, or not yet learned. Update training dates, revision records, planned US tasks, and the trainer. Specialized knowledge must relate to the company’s products or reflect advanced command of company processes; familiarity with an obsolete version does not prove mastery of a replacement, yet unchanged expertise need not be discarded. Confirm the underlying transfer elements too: one continuous qualifying foreign year within the relevant three years, an active parent, branch, subsidiary, or affiliate relationship, and petitioner control over the assignment. Avoid scheduling productive work before the employee knows the method and has authorization. The L-1B maximum remains five years, while a new-office approval initially lasts one year.
Hypothetical example: A resin-formulation technician near Petit-Saguenay learned the employer’s established mixing sequence, but the US affiliate adopts a new curing-control stage before transfer. Revision comparisons show that ingredient diagnostics remain useful while software settings require fresh instruction. The company completes supervised training abroad, records competency on the revised stage, and updates the duty statement before filing. It postpones the start if evidence cannot support the claimed knowledge, rather than backdating training or pretending the earlier procedure is identical.
