Reassess the knowledge claim and actual role rather than assuming the existing description covers any company technology.
Compare the duties before proceeding
Identify the new work, required knowledge and supervision. The consequences depend on the change and stage, so preserve both versions for review.
The order that works is: settle the commercial contract with the client so it describes the company's deliverable, then write the specialized-knowledge case around the employee's role in delivering it, then file. Separate information gathering from hands-on diagnosis, code changes, configuration, or customer delivery, and obtain advice about the employee’s location and existing status. L-1B supports special organizational knowledge or an advanced level of process-and-procedure knowledge; a delayed launch cannot be filled with generic labour unrelated to that claim. A move into a managerial or executive role can be recognised by a new L-1A petition, but that is a change of classification with its own evidence, and time already spent in L-1B counts toward the seven-year executive maximum rather than starting afresh. A multi-terminal program running past five years needs either recaptured time abroad, a genuine change to a managerial role, or a different classification arranged well before the limit is reached. Explain the employee’s knowledge, qualifications and proposed services, and have any additional professional requirement reviewed rather than promising eligibility from a diploma or experience alone.
