What changed
The Child Status Protection Act of 2002 (Pub. L. 107-208) was signed into law on August 6, 2002. It added INA § 203(h), which protects certain children from “aging out” of derivative or beneficiary status because of immigration-system delay. The most operationally important provision is § 203(h)(1) — the age-calculation formula.
The Act has not been amended since 2002, but USCIS’s reading of “visa availability” has. On February 14, 2023, USCIS updated the Policy Manual, Volume 7, Part A, Chapter 7, to clarify that “visa availability” for CSPA § 203(h)(1)(A) purposes is based on the Dates for Filing chart in the Visa Bulletin, not the Final Action Dates chart, when USCIS is honoring Dates for Filing for I-485 acceptance that month. The change locked in CSPA ages for a large cohort of beneficiaries who had been at risk of aging out.
Why it matters
A “child” for immigration purposes is unmarried and under 21. Without CSPA, a derivative child whose I-130 or I-140 wait crossed her 21st birthday lost derivative status entirely — she had to be re-petitioned, usually in a slower line, often by a parent who had become a U.S. citizen and was now stuck filing F1 (a slower line than her former derivative path). CSPA addresses this by freezing the child’s CSPA age at a specific point in the process.
For employment-based cases (EB-1, EB-2, EB-3, and certain EB-4 / EB-5 derivatives), the freeze runs through INA § 203(h)(2). For family-preference cases (F1, F2A, F2B, F3, F4) the freeze also runs through § 203(h). For immediate-relative children of U.S. citizens, INA § 201(f) provides separate, more generous protection.
Way forward
Memorize the § 203(h)(1) formula. CSPA age =
age of the child on the date a visa number becomes available to the principal
minus
the number of days the petition (I-130 or I-140) was pending (filing date to approval date).
If the resulting CSPA age is under 21, the child is a “child” for derivative purposes.
Identify “visa number becomes available.” Under USCIS Policy Manual Volume 7, Part A, Chapter 7, as updated February 14, 2023, “visa availability” is the LATER of (a) the date the petition was approved and (b) the first day of the month in which the priority date is current on the chart USCIS honors that month — Dates for Filing if USCIS is accepting I-485 on DFF, Final Action Dates otherwise. The 2023 update was significant because Dates for Filing is more generous, so children whose CSPA age would have been frozen above 21 on Final Action Dates may now be frozen below 21 on Dates for Filing.
Calculate the “pending” period correctly. “Pending” means from the Form I-130 or Form I-140 filing receipt date to the approval-notice date. A petition that was rejected and re-filed does not get to count the rejection period. Premium processing makes the petition pending for fewer days, which is generally good for the child (less subtraction means a higher CSPA age — but in CSPA the goal is a LOWER CSPA age, so a longer pending period helps). This counterintuitive result — that delay HELPS the child — is the central CSPA insight.
Worked example — F2B. I-130 filed January 15, 2018, approved March 1, 2021 (1,141 days pending). Child’s biological age on January 1, 2026 (when the F2B priority date becomes current on the chart USCIS honors that month): 21 years, 8 months. CSPA age = 21 years 8 months − 1,141 days ≈ 18 years 7 months. The child is under 21 for CSPA purposes and qualifies as a derivative on the parent’s F2B visa.
Apply the “sought to acquire” requirement. INA § 203(h)(1)(A) requires the alien to “have sought to acquire” lawful permanent residence within one year of visa availability. The BIA in Matter of O. Vazquez, 25 I&N Dec. 817 (BIA 2012) construed this. See our companion article on “sought to acquire” for the operational definition.
File the I-485 or DS-260 inside the one-year window. The most common CSPA failure is not the math — it is missing the one-year “sought to acquire” deadline. The clock starts the day the priority date becomes current on the controlling chart and runs for 365 days. File the I-485 (in the U.S.) or the DS-260 (abroad) inside that window even if you have to file before all documents are gathered — supplementing later is easier than restarting.
Document the calculation in the filing. USCIS adjudicators do the CSPA math at I-485 adjudication. Include in the cover letter a CSPA-age computation showing (a) the priority date, (b) the date the priority date became current on the relevant chart, (c) the I-130 or I-140 filing and approval dates, (d) the pending-petition day count, and (e) the resulting CSPA age. Attaching the math saves the case from a Request for Evidence.
Beware retrogression. If a priority date becomes current, then retrogresses before the I-485 is filed, the “visa availability” date for CSPA does NOT reset — see the USCIS Policy Manual update at Volume 7, Part A, Chapter 7. The first time the priority date became current on the controlling chart is the date used.

Fola is a software company, not a law firm, and nothing in this article is legal advice. The CSPA age calculation is fact-sensitive and turns on USCIS’s current Policy Manual reading and the controlling Visa Bulletin chart that month. Verify against INA § 203(h), USCIS Policy Manual Volume 7, Part A, Chapter 7, and Matter of O. Vazquez, and consult a qualified U.S. immigration attorney before relying on a CSPA calculation in a real case.
