Do not assume it does. The USCIS regulation states that a rejected request does not retain a filing date, so assess the actual effects on the family case.
Review individual consequences of the corrected timeline
A qualifying spouse and unmarried children under 21 may seek derivative status subject to individual requirements and applicable age rules. The family should not rely on an unretained date as proof of age protection or completed immigration processing.
The family should retain lawful source-and-path evidence for the required capital and understand that residence is conditional for two years and Form I-829 must be filed during the 90-day period immediately preceding its second anniversary. Identify the principal investor, the source and use of funds, and each family member’s applicable process. The whole family's permanent status rides on that later petition, so the investor should insist on knowing what job evidence the regional center will supply then. A child who may approach the applicable age threshold needs a timeline analysis rather than reassurance based on the parent’s filing date alone. Record each family member's citizenship and Canadian status because consular processing will require civil documents for each.
