During that wait, a beneficiary’s child can turn 21 and — under the ordinary definition in the Immigration and Nationality Act — stop qualifying as a “child.” When that happens, the child “ages out” and generally loses the ability to immigrate as a derivative on the parent’s petition. Congress enacted the Child Status Protection Act (CSPA) in 2002 to protect certain children from losing eligibility purely because of processing delays. CSPA does this with a special age calculation that can leave a child legally “under 21” even after their actual birthday has passed.
Why children “age out”
For a family-sponsored, employment-based, or diversity immigrant case, an unmarried child generally must be under 21 to get lawful permanent resident status as a derivative of an approved petition. The catch is timing: a visa number has to be “available” before the child reaches that age. With long priority-date backlogs for countries such as India and China, and even for family categories like F2A/F2B/F3/F4, it is common for a child to turn 21 while waiting. CSPA was designed for exactly this problem.
The CSPA age formula
The core calculation is straightforward:
- Petition-pending time runs from the date the immigrant petition (for example, Form I-130 or I-140) was filed to the date it was approved.
- The date a visa becomes available is the later of (a) the date the immigrant petition is approved, or (b) the date the priority date becomes current.
- If the resulting CSPA age is still under 21, the child is treated as a “child” for that green-card case.
Which Visa Bulletin chart decides “available” (2025 update)
The Visa Bulletin publishes two charts — Final Action Dates and Dates for Filing. On August 15, 2025, USCIS updated its policy so that both USCIS (for adjustment of status) and the Department of State (for consular processing) use the Final Action Dates chart to determine when a visa becomes available for CSPA purposes. The goal was consistency: before this change, USCIS had used a different “visa available” trigger (its Feb. 14, 2023 policy), which could produce different CSPA ages for people adjusting in the U.S. versus people processing at a consulate abroad.
The update applies to requests filed on or after August 15, 2025. For adjustment applications already pending with USCIS before that date, USCIS applies the earlier Feb. 14, 2023 policy, recognizing that those applicants may have relied on it when they filed.
The “sought to acquire” 1-year rule
CSPA protection is not automatic just because the math works. The child must seek to acquire lawful permanent residence within one year of a visa becoming available. In practice this means taking a concrete step — for someone in the U.S., filing Form I-485 (Adjustment of Status); for someone abroad, moving the case forward through the National Visa Center (for example, paying the required fees and/or submitting the online DS-260 immigrant visa application).
If the one-year window was missed, the child is not necessarily out of options. In Matter of O. Vasquez (BIA 2012), the Board of Immigration Appeals held that an applicant can still satisfy “sought to acquire” by showing extraordinary circumstances — particularly where the failure to file on time was due to circumstances beyond the applicant’s control. USCIS codified this in its Policy Manual.
Worked example
| Event | Child’s actual age | What it means for CSPA |
|---|---|---|
| I-130 filed | 19 years, 0 months | Start of petition-pending clock |
| I-130 approved | 20 years, 0 months | Petition pending = 12 months |
| Priority date current (Final Action Dates) | 21 years, 3 months | “Visa available” = later of approval / current = this date |
| CSPA age | 20 years, 3 months | 21y3m − 12m = 20y3m → still under 21, child protected |
The child must still file (or take the consular step) within one year of the priority date becoming current. The example shows the age side; the one-year “sought to acquire” clock is a separate, required step.
Where CSPA matters most
- Employment-based derivatives (EB-1/EB-2/EB-3): long backlogs for India and China make CSPA critical for beneficiaries’ children. If an applicant has multiple approved petitions, USCIS calculates the CSPA age using the petition that forms the underlying basis of the pending adjustment.
- Family-sponsored preferences (F1–F4): the per-country cap drives multi-year waits, especially for Mexico, India, and the Philippines.
- Diversity (DV) immigrants: CSPA applies to derivative children of DV principals as well.
- Immediate relatives: spouses, minor children, and parents of U.S. citizens are not subject to numerical limits, so there is generally no visa-number wait for the child to age out against — but the child still must be under 21 by actual age for the immediate-relative relationship itself.

Frequently Asked Questions
What is the CSPA age formula?
CSPA age = the child's age on the date an immigrant visa number 'becomes available,' minus the number of days the underlying immigrant petition was pending (from filing to approval). If the result is still under 21, the child is protected as a 'child' for immigration purposes.
When does a visa 'become available' for CSPA?
As of the Aug. 15, 2025 USCIS update, both USCIS and the Department of State use the Final Action Dates chart of the Visa Bulletin to determine when a visa becomes available. That date is the later of the date the immigrant petition is approved or the date the priority date becomes current on the Final Action Dates chart.
What is the 'sought to acquire' 1-year rule?
To benefit from CSPA, the child must seek to acquire lawful permanent residence within one year of a visa becoming available — for example, by filing Form I-485 (adjustment) or taking the steps to start consular processing (such as paying NVC fees / submitting the DS-260). Extraordinary circumstances that prevented timely filing can satisfy this requirement (Matter of O. Vasquez).
Does CSPA apply to immediate relatives of U.S. citizens?
Immediate relatives (spouses, minor children, and parents of U.S. citizens) are not subject to numerical visa limits, so there is generally no priority-date wait for the child to 'age out' against. CSPA is most important for family-sponsored, employment-based, and diversity preference cases, where a visa number must become available before the child turns 21 (as calculated under CSPA).
