Well past approval. Conditional permanent residence lasts two years, and the I-829 petition to remove conditions is ordinarily filed within the ninety days before the second anniversary of conditional admission.
Two years after the good news, a filing falls due
Hypothetical example: Households tend to plan intensively up to approval and then stop, which leaves the last obligation to be remembered under pressure. The conditional period is where the substantive proof happens: the capital has to remain invested, the enterprise has to operate, and the jobs have to materialise. The removal filing then asks for evidence of all three.
A Selwyn family should put the conditional admission date, the second anniversary, and the opening of the ninety-day window into the same calendar that holds everything else, and should keep the enterprise's records on the assumption that they will be read. Approval of the initial petition is a milestone rather than a conclusion, and treating it as the end of the project is the most common way a compliant investment becomes a difficult file.
