A gift acknowledgment alone is not a reliable basis for treating the immigration process as complete. Confirm the actual remaining steps before making irreversible moving commitments.
Make a move plan that can respond to the decision
Keep lease, employment and school arrangements distinguishable from official processing. A desired departure date does not establish visa availability or override an unresolved case; do not announce an approved arrival date that the record does not support. Write the moving plan as a sequence of commitments with a note beside each saying what makes it reversible and what it costs to unwind: the notice period in the lease, the deadline for withdrawing a school registration, the resignation date, the cancellation terms agreed with a mover.
Then mark which of them are currently triggered by something in the record and which are triggered only by an expectation. Hypothetical example: a household gives notice on a home once an acknowledgment arrives, and a later request for further information extends the process by months, leaving them without a residence and without a confirmed date. The acknowledgment was accurate; the inference drawn from it was not.
Keep arrangements changeable for as long as the process remains open, and give notice against a document stating an outcome rather than against a hoped-for one. A desired departure date creates no entitlement and moves no deadline.
