No. Response dates in a capital call come from the contract you signed, not from USCIS or the Department of State. Confirm the date and its calculation against the executed agreement, and ask whether an extension or a partial contribution is permitted without assuming that an enquiry changes the existing deadline.
Two clocks, running independently
Your immigration clock is set by filing, visa availability under the Visa Bulletin, and later the removal of conditions, which is ordinarily filed during the ninety-day period immediately before the second anniversary of conditional residence. The contract clock is set by the notice. Neither controls the other, and there is no universal rule returning capital after two years or defining a single sustainment period.
Anchor the immigration calendar to the investor's actual admission or adjustment as a conditional permanent resident. Keep three clocks visible: petition preparation and adjudication, visa availability or adjustment, and the project’s job-creation schedule. After the money trail is coherent, test the investment independently: the required capital must remain exposed to loss for the required period, the enterprise must create the required jobs, and residence begins conditionally only after the applicable immigrant-visa admission or adjustment.
