No universal response should be assumed. Assess the actual change, governing rules and case stage; a private revision does not itself extend the I-829 window.
Use the correct process for the changed facts
Retain the original and revised evidence and obtain the applicable procedural assessment. An approval based on earlier facts is not a guarantee about every later arrangement, and a proposed new phase does not begin a new period of conditional residence.
The usual I-829 window is tied to the second anniversary of conditional residence, not the capital-adjustment date. After approval, immigrant-visa processing follows visa availability, and conditional residence begins on admission, from which the I-829 window is counted. Preparation of the equity source-of-funds file itself typically takes weeks to months. The common mistake is waiting for the filing window before reconstructing personnel history. Not every operational change carries the same procedural weight, and sorting them early avoids later rework. A change that alters the investment amount, the job-creation methodology, or the enterprise structure differs from a change that only affects daily management of an already-approved business. Whether the correct step is disclosure, an amendment, or a fresh review depends on which petition the investor holds: a standalone filing rests on its own facts, while a regional-center filing also depends on that center's separate project application. Track each change against the facts the original petition presented, noting the date it actually occurred rather than the date it was noticed. Use that timeline, not the loan or construction schedule, for any later procedural assessment.
