Leave room for delay at each stage. A scheduled interview guarantees neither approval nor a moving date: assess housing, schooling, and business commitments through the decision and applicable admission steps. Published expectations in weeks are not a guaranteed timeline, and a pending application does not authorize work.
Two calendars: yours and the visa bulletin's
Picture a planned opening of a hypothetical distribution site in Georgia set for a fixed date. If the classification or chargeability turns out differently than assumed, the opening slips, not the queue. Build lease clauses, staffing and travel around a range rather than a single date. Any right to work in the United States before permanent residence would have to come from separate, valid authorisation you already hold.
Application and the nonrefundable processing fee come first, then vetting, then the gift, then the immigrant-visa or adjustment stage. The published sequence begins with a processing fee that is not returned under any outcome. Timely responses matter, but advertised processing expectations do not guarantee a particular residence date or eliminate visa-availability constraints. Irreversible personal decisions should follow an actual decision on your case, not a published schedule.
