Wait if the hire is an unresolved essential condition of the proposed operations. If a lawful, documented alternative permits launch, assess whether the case is ready without this candidate's acceptance. The schedule should reflect permits, commitments, and staffing actually available, without a guaranteed processing time.
Keep the employee's own route a separate question
If the eventual candidate needs immigration authorization, that is an independent assessment with its own requirements and no assured outcome; nothing about the investor's case guarantees it. Build the timeline so the enterprise can open without it. Note also that visa validity and the authorized period of stay recorded at admission are different things, and that the plan should remain consistent with departing when status ends.
Set dates for the funds trail, signed vendor and hosting commitments, the business plan, and counsel's review — those you can schedule. Build the launch calendar around milestones you control — agreement executed, permissions filed, equipment ordered, first production run scheduled — because no processing time, appointment date or outcome can be guaranteed. Plan in the order the transaction can actually occur: source records, entity and agreement, commitment of funds, business evidence, application, and admission planning.
Identify which steps actually depend on the new passport, including form details, scheduling and travel; a delay may affect more than the final step.
