The opening date is a business deadline, not immigration authorization. Include pre-opening recruitment, training and setup duties in the proposed timeline. Have the actual earliest work and its location assessed before committing to participation.
Plan from the first management responsibility
A manager may be expected to assign staff or prepare operating procedures before guests arrive. Those tasks belong in the factual account. Coordinate the lawful start with the employer rather than treating pre-opening duties as automatically outside the work arrangement.
Build the schedule backwards from the first duty that is unmistakably work, then forwards again from the earliest date the qualification evidence can be complete. Where those two dates cross, it is the opening calendar that has to move, because the alternative is a start date the file cannot support. Pre-opening tasks — writing operating procedures, interviewing candidates, receiving deliveries — belong in the factual account of the position rather than in an informal period described as preparation.
Ask the employer to name, in the offer, the first day the person is expected to perform any of them. While the credential question stays open, the useful work is documentary: assemble the program record, the chronology and the employer letter so that nothing except the review itself remains on the critical path. No processing or examination time is guaranteed, and a schedule that depends on a particular decision date has a single point of failure.
