Overview: Passing 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 age calculation, ending up under 21 after subtracting the petition's pending time, is only half of what protects a child from aging out. 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 must also "seek to acquire" lawful permanent residence within one year of the visa becoming available, generally by filing an Adjustment of statusThe process of applying for a green card from within the United States, rather than through a consulate abroad. Filed on Form I-485.See it in the glossary application or paying the Immigrant visaA visa issued at a consulate to a person intending to live permanently in the United States. On admission the holder becomes a permanent resident.See it in the glossary fee. Missing that one-year deadline can forfeit CSPA protection even when the age math would otherwise have worked.
What the age calculation alone determines
The CSPA age formula, actual age at visa availability minus days the petition was pending, produces a single number. If that number is under 21, the beneficiary clears the first of two separate requirements CSPA imposes.
What "sought to acquire" requires beyond the math
Separately from the age calculation, the beneficiary must take an affirmative step evidencing intent to acquire permanent residence within one year of the visa becoming available. This generally means filing Form I-485Application to Register Permanent Residence or Adjust Status, the form used to apply for a green card from inside the United States.See it in the glossary for adjustment of status, or paying the required fee to the National Visa Center (NVC)The State Department office that collects fees and documents from approved petitioners before a case is scheduled at a consulate.See it in the glossary for Consular processingApplying for an immigrant visa at a U.S. embassy or consulate abroad, as an alternative to adjustment of status inside the United States.See it in the glossary, within that one-year window.
Why meeting one requirement doesn't excuse missing the other
A beneficiary whose CSPA age calculates to 19, comfortably under 21, still loses CSPA protection if they fail to file the required paperwork or pay the required fee within one year of visa availability. The favorable age number alone does not protect anyone who misses this second, entirely separate deadline.
What can excuse a missed sought-to-acquire deadline
USCIS guidance allows for extraordinary circumstances to excuse a missed sought-to-acquire deadline in some cases, but this is a discretionary exception evaluated on the specific facts, not something a beneficiary should assume will apply.
Why this deadline is easy to miss in practice
Because families are often focused on tracking the Visa BulletinA monthly State Department publication showing which family and employment visa categories currently have visas available.See it in the glossary and the underlying age math, the separate one-year action deadline can be overlooked, particularly when a visa becomes available during a period of confusion about exactly which chart triggered availability in the first place.
Tracking both requirements as genuinely separate deadlines
Anyone monitoring a child's CSPA eligibility should track the age calculation and the one-year sought-to-acquire deadline as two entirely independent items, since success on one provides no protection at all against failure on the other.
