They are unrelated events. The petition to remove conditions is ordinarily filed in the ninety days before the second anniversary of obtaining conditional residence. A project's repayment may fall before, after, or nowhere near that window. Never treat the two-year residence period as a schedule for getting capital back.
Diary both sequences independently
One sequence belongs to the case: petition filing, adjudication with no fixed decision date, visa availability in the relevant category, admission or adjustment, then the conditional residence period. The other belongs to the project: construction, stabilisation, loan maturity, extensions, exit. Write them side by side so the gaps are visible.
When the sponsor changes a date, update only the project column and check whether any financial assumption needs revisiting. Write the two sequences side by side in one document. The case sequence runs from petition filing through adjudication with no fixed decision date, visa availability in the relevant category, admission or adjustment, then the two-year conditional residence period, with the petition to remove conditions ordinarily filed in the ninety days before its second anniversary.
The project sequence runs from construction through stabilisation, loan maturity, extensions, and exit. Seeing them together makes plain that neither drives the other. When the sponsor changes a date, update only the project column, then check whether any financial assumption in the household budget depends on it.
Never treat the residence period as a schedule for the return of capital.
