No. Final billing can describe the adviser’s accounts without establishing an immigration decision.
Check the actual case record
Moving and employment plans should reflect real permission, not the accounting status of a private invoice.
Choose reversible commitments while the case is pending: month-to-month housing where possible, school enrolment deadlines noted rather than assumed, and employment notice given only when a step is actually complete. The published sequence is application and processing fee, vetting, gift and then immigrant processing under EB-1 or EB-2, with the applicant becoming a permanent resident only when that final step is complete and a visa number is available. Track actual official instructions and outcomes rather than converting a private service deadline into a guaranteed residence date. Keep copies of the question sent, delivery proof, any response and the original notice; only an actual official instruction should change the due date. A scheduled interview guarantees neither approval nor a moving date: assess housing, schooling, and business commitments through the decision and applicable admission steps. Do not assume a private preparation delay changes an official date or that a generic package guarantees a favourable decision.
