Do not use a universal waiting period. The relevant consequences depend on the actual decision, facts and rules applicable to the new case. Sequence rather than wait. The useful question is not how long to pause but which step unlocks the next: obtaining the decision record, assessing its effect, selecting a project whose terms suit that assessment, then subscribing and filing. A year spent waiting produces nothing; a month spent obtaining the notice usually produces the answer that governs everything after it.
Base timing on the identified issue
A delay alone is not proof that the problem disappeared, and a new category does not guarantee immediate eligibility. Confirm the remaining process and visa availability before treating a proposed move date as settled. Several clocks run at once and they are not synchronised.
The project has its own construction or deployment schedule. Visa availability is governed by the applicable rules and is outside anyone’s control. Conditional residence, once it begins, runs to a fixed point at which the petition to remove conditions must be filed, and the evidence for that filing accumulates during the intervening period rather than being assembled at the end.
Ask which of these your own decisions can influence and which they cannot, then plan the parts you control. Moving dates, resignations and school enrolments belong behind confirmed steps, not behind an estimate; an estimate that slips costs the household the difference, and no processing time is guaranteed.
