Training completion does not itself grant U.S. work permission.
Review the actual placement and authorization
Assess genuine supervision, purpose and process requirements before performance. A course end date is not an immigration decision.
A specialized-knowledge case may take longer if USCIS issues a request for additional evidence, so do not commit to a U.S. start date before reviewing the actual processing path. Preserve actual operating records and review changes in duties or funding rather than assuming the initial approval guarantees an extension. Compare installation, training, trial production, and steady operation; identify remaining duties, supervision, and location. Identify which facts require fresh review and whether further filings are needed before the new activity begins, and keep the actual approval and status dates visible rather than relying on an external delivery deadline. 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. A delivery deadline does not establish authority to begin a materially different assignment while the immigration questions remain unresolved.
