Last reviewed September 2026 -- CSPA chart guidance has changed twice recently, recheck current USCIS Policy Manual before relying on this
Overview: The Child Status Protection Act lets a derivative child subtract the time their petition spent pending with USCIS from their actual age at the moment a visa becomes available, and if the result is under 21, they generally keep their status as a child instead of aging out. Family and employment-based cases use the same underlying formula, but which Visa Bulletin chart triggers the calculation, and how long each type of case typically sits pending, differs enough between the two that the practical risk of aging out is not the same across both.
The shared CSPA formula
In both family and employment cases, CSPA age equals the beneficiary's actual age on the date a visa becomes available, minus the number of days the underlying petition was pending at USCIS between filing and approval. If that result is under 21, the beneficiary generally retains eligibility to immigrate as a child rather than aging out into a different category or losing eligibility.
Which Visa Bulletin chart currently triggers the calculation
The Visa Bulletin publishes two charts each month, Final Action Dates and Dates for Filing. Which one USCIS uses to fix the "visa available" date for CSPA purposes has changed more than once in recent years; guidance that took effect August 15, 2025 aligned USCIS with the Department of State on using the Final Action Dates chart. Given how recently this changed, and that it changed once before, current guidance should be confirmed directly before relying on either chart for a specific calculation.
Why employment-based pending times can differ sharply from family-based ones
An employment-based I-140 petition's pending time is measured only from filing to USCIS approval, which can be quite short with premium processing, while a family-based I-130's pending time is measured the same way but has historically run longer in many categories, meaning the same formula can produce very different amounts of "credit" depending on which type of petition is involved.
The one-year "sought to acquire" requirement in both contexts
Beyond the age math itself, both family and employment-based CSPA cases require the beneficiary to take an affirmative step toward permanent residence, generally filing an adjustment of status application or paying the immigrant visa processing fee, within one year of the visa becoming available under the chart currently in use. Missing this deadline can forfeit CSPA protection even where the age calculation would otherwise succeed.
Why employment-based derivatives face a distinct wrinkle
Employment-based cases often involve a gap between when the Dates for Filing chart allows an early adjustment filing and when the Final Action Dates chart actually makes a visa available, and because current guidance ties the CSPA age freeze to Final Action Dates specifically, filing early under Dates for Filing does not by itself lock in a favorable CSPA age.
Confirming current guidance before relying on any specific calculation
Because this area has changed more than once and depends on the specific interaction between a family or employment petition's pending time and current Visa Bulletin chart guidance, anyone approaching a child's 21st birthday with a pending case should confirm the current calculation method rather than relying on an older explanation, including this one.
