Family eligibility and child-age protection require individualized review. CSPA can affect the calculation, but a child's age is not simply frozen by making the investment or filing the petition — visa availability and other conditions also matter.
Bring the actual dates before choosing a timetable
Record birth dates, the petition's own history, and the family's intended arrangements. Have counsel apply the applicable rules and deadlines rather than relying on a rough estimate. Keep school enrolment plans separate from status eligibility — neither a school admission nor an investment payment extends a child's qualifying age or guarantees the whole household completes the process on the same schedule. Derivative family eligibility generally covers a spouse and unmarried children under 21, subject to applicable CSPA protection. A sibling is not a derivative merely because sale proceeds were shared. For immigrant-visa entry, the principal must arrive before or with derivatives.
Create an age-and-process calendar for the principal, spouse, and every child using actual birth dates and case milestones. EB-5 permits a spouse and unmarried children under 21 to derive; the Child Status Protection Act can protect some children, but it requires individualized calculation rather than an assumption that payment freezes age. Plan for two-year conditional residence, remembering that Form I-829 is filed within the 90 days before its second anniversary. The common mistake is tying school or housing commitments to a rough petition forecast while ignoring visa availability, admissibility, and separate travel sequencing.
Hypothetical example: a Windsor secondary-school principal invests while her unmarried son approaches age 21 and her spouse expects to finish a Canadian teaching term. They bring civil records, petition history, visa-availability information, and proposed entry order to counsel for CSPA review. The family keeps the son's college deposit changeable and records when conditional residence begins. They calendar the later I-829 window from that anniversary, not from the investment date or an estimated project milestone.
