Overview: The Child Status Protection Act (CSPA)A federal law that changes how age is calculated for certain children in the green card process, so a child who turns 21 while a case is pending may still be treated as a child. The result is called the CSPA age. For adjustment of status applications filed on or after August 15, 2025, USCIS treats a visa as available based on the Final Action Dates chart in the Visa Bulletin.See it in the glossary 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 BulletinA monthly State Department publication showing which family and employment visa categories currently have visas available.See it in the glossary 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 BeneficiaryThe person on whose behalf a petition is filed, such as the relative or worker who would receive the immigration benefit.See it in the glossary'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 DatesThe Visa Bulletin chart showing the priority dates for which a visa number can actually be issued or a green card approved in that month.See it in the glossary and Dates for FilingThe Visa Bulletin chart showing the earliest priority dates for which applicants may submit documents, or in some months file for adjustment of status, ahead of a visa number being available.See it in the glossary. 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-140Immigrant Petition for Alien Worker, filed by an employer (or in some categories the worker) to classify a person under an employment-based category.See it in the glossary petition's pending time is measured only from filing to USCIS approval, which can be quite short with Premium processingAn optional USCIS service, requested on Form I-907 with an additional fee, that sets a fixed time frame for USCIS to act on certain petitions and applications. Within that time USCIS must issue an approval, denial, request for evidence or notice of intent to deny, or open a fraud investigation. It speeds up when USCIS acts, not the standard the case must meet, and only some forms and categories are eligible.See it in the glossary, while a family-based I-130Petition for Alien Relative, filed by a U.S. citizen or permanent resident to establish a qualifying family relationship with an intending immigrant.See it in the glossary'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 in the USCIS Policy Manual rather than relying on an older explanation, including this one.
