No. The intended activity and required authorization must be assessed independently of the venue contract.
Coordinate the event with the actual process
Identify what work will be performed, for whom and under whose supervision. A session described as training can still involve US work requiring appropriate permission. Keep cancellation or rescheduling terms visible, but do not make the commercial booking a reason to bypass unresolved knowledge, foreign-employment or worksite conditions.
Before filing, the evidence gathering — training records from the learning-management system, procedure version histories, an addendum to the client contract — typically takes a few weeks. 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. Confirm as well the employee's continuous qualifying foreign year within the preceding three, the active parent, subsidiary, affiliate or branch relationship and the petitioner's control over any client-site work. Keep remote preparation from abroad distinct from work performed inside the United States, and do not treat the training launch date as a government decision deadline.
