No. Appointments and logistics do not authorize the activity. Assess the actual classification and process before relying on scheduled visits.
Review substantive changes
If duties, supervision or worksite change, describe the new arrangement. A repeated calendar entry does not establish that earlier permission covers it.
Keep the actual approval and status dates visible throughout, and do not treat a client delivery deadline as permission to begin work whose immigration basis has not actually been resolved. 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. If the employee begins mainly performing routine work or the business adopts a different system, reassess the classification rather than relying on the original filing narrative.
