How CSPA Protects Derivative Beneficiaries from Aging Out

The Child Status Protection Act lets a derivative child stay eligible for a green card even when they turn 21 during the wait, and CSPA protection for derivative beneficiaries works by subtracting the time the underlying petition sat pending from the child’s biological age on the date a visa number becomes available. If that adjusted age is under 21, and the child takes a qualifying step toward a green card within one year of that visa availability, they keep their place in the case. If they still age out, they hold onto the original priority date and the petition converts to a new category rather than starting over.

Which Derivatives CSPA Covers

A derivative beneficiary is the unmarried child (under 21 at the time the petition is filed) of the person a petition names as the principal. CSPA reaches derivatives across nearly every immigrant category:

Derivative children on family preference petitions, including F2A children of permanent residents.¹
Derivative children on employment-based petitions from EB-1 through EB-5.
Children of diversity visa lottery winners.
Derivative children on VAWA self-petitions.²
Derivative children of refugees and asylees, under a separate freeze rule.

Children of U.S. citizens are immediate relatives, not derivatives, and the file notes their age is simply locked when the I-130 is filed. The rest of this article addresses derivatives, where the formula and the deadlines actually matter.

How the CSPA Age Formula Works

For family preference, employment-based, and diversity cases, CSPA does not freeze age on the filing date. It runs a two-step calculation:¹

Take the child’s biological age on the date a visa number becomes available.
Subtract the number of days the petition was pending (from the filing date to the approval date).

The result is the CSPA age. Under 21, the child is still a child for immigration purposes. At 21 or older, the child has aged out for eligibility, though the priority date still counts.²

A worked example. A child is 21 years and 60 days old on the date a visa number becomes available. The petition took 200 days from filing to approval. Subtract 200 days from 21 years and 60 days and the CSPA age comes to roughly 20 years and 225 days. Under 21. Still eligible.

Which Visa Bulletin Chart Sets the Availability Date

The visa availability date comes from the monthly Visa Bulletin published by the Department of State.³ A visa is available on the first day of the month in which the applicant’s priority date is current.

As of August 15, 2025, USCIS uses only the Final Action Dates chart for CSPA age calculations. A 2023 policy had allowed the Dates for Filing chart, which sometimes produced a younger CSPA age; that policy was revoked to align adjustment applicants with those going through consular processing.⁴ Adjustment applications filed before August 15, 2025 are still calculated under the older policy.⁵

Do not confuse this with USCIS’s monthly guidance on which chart to use when filing Form I-485.⁶ Even months when USCIS tells applicants to file under Dates for Filing, the CSPA age itself is now measured against Final Action Dates.

The One-Year Sought-to-Acquire Deadline

A CSPA age under 21 is not enough on its own. The derivative must also take a concrete step toward the green card within one year of the visa becoming available.¹ Missing that window can end CSPA protection outright, even when the arithmetic would have kept the child under 21. Families most often lose eligibility here, not on the formula, because visa numbers can become current for a brief window before the Bulletin retrogresses again.

USCIS accepts several actions as meeting the requirement:²

Filing Form I-485 if the child is inside the United States.
Submitting a completed Part 1 of Form DS-260 if the child is abroad.
Paying the immigrant visa fee to the Department of State.
Paying the Affidavit of Support (I-864) review fee, provided the child is listed on the affidavit.
Having Form I-824 properly filed on the child’s behalf.
Sending a written request to transfer the basis of a pending adjustment application to a new preference category.

Any one action is enough. The green card process does not need to finish within the year; it just needs to have started.⁷ Filing before a visa becomes available also counts. The sought-to-acquire requirement does not apply to immediate relatives, derivative asylees, or derivative refugees.

Missing the Deadline: Extraordinary Circumstances

USCIS can excuse a missed one-year deadline if the applicant shows extraordinary circumstances. Three elements have to line up: the circumstances were beyond the applicant’s control, they directly caused the delay, and the length of the delay was reasonable in context.⁸

Situations USCIS has treated as potentially extraordinary include:

Serious illness or physical or mental disability during the one-year window.
Death or serious illness of a close family member or of the applicant’s attorney.
Ineffective assistance of counsel, with specific documentation.
A timely adjustment application that USCIS rejected for a procedural error, then corrected and refiled promptly.

Ordinary financial stress, minor health problems, and simply not getting around to hiring an attorney do not qualify. Being young at the time is not itself an extraordinary circumstance, even though CSPA applicants are by definition young.⁸

One targeted exception exists for the 2023 policy change. If a visa became available under the earlier Dates for Filing approach before August 15, 2025 and the applicant relied on it but did not file in time, USCIS may still calculate the CSPA age under the more favorable earlier policy, so long as the delay itself was reasonable.⁴

If the Child Ages Out Anyway

Even when the formula produces an age of 21 or older, the case does not vanish. Under INA 203(h)(3), the petition automatically converts to the appropriate new category and the beneficiary keeps the original priority date.¹ Years of waiting are preserved.

The most common example: a derivative in F2A (child of a permanent resident) who ages out becomes a principal beneficiary in F2B (unmarried adult child of a permanent resident). No new petition is required, and the original priority date carries over.⁹ The F2B backlog is often longer than F2A, so the practical wait usually stretches out, but the applicant is not sent back to the start of the line.

Priority date retention also applies to derivatives on employment-based petitions who age out. They convert to the appropriate family preference category based on their relationship to the petitioner and bring the employment-based priority date with them.

Marriage Ends the Protection

A child must be unmarried to benefit from CSPA. Marriage before the green card is granted destroys eligibility because immigration law defines a “child” as unmarried.⁸ This applies to every category above, including VAWA and diversity visa cases.

Derivative refugees are the narrow exception. They must be unmarried when they receive derivative refugee status, meaning when the I-730 is approved or when they enter the United States, but they do not have to stay unmarried to later adjust status under INA 209.

Refugee and Asylee Derivatives: A Different Freeze

Derivative children of asylees and refugees get CSPA protection, but the mechanic is a simple age freeze rather than a formula.

Derivative asylees: age is frozen on the date the principal filed Form I-589. A child under 21 and unmarried on that date will not age out.⁸
Derivative refugees: age is frozen on the date of the principal’s interview with a USCIS officer, which is treated as the filing date for the I-590.

Neither group is subject to the one-year sought-to-acquire deadline, which is a meaningful advantage over the family and employment preference categories. To qualify, the child must have had a qualifying petition (I-730, I-589, or I-485) pending on or after August 6, 2002, the date CSPA took effect.

When a Permanent Resident Parent Naturalizes

Naturalization of the petitioning parent changes the category, and that change interacts with CSPA in ways worth planning for.

If the derivative is in F2A (under 21 and unmarried), the petition converts automatically to an immediate relative petition when the parent becomes a citizen. Immediate relatives have no annual cap and no visa backlog, so this normally means immediate visa availability.⁹ One catch: when the petition converts to immediate relative, any derivative beneficiaries on that petition, such as the primary beneficiary’s own children, lose derivative eligibility. Each such person now needs a separate I-130.

For an adult unmarried child in F2B, the naturalization converts the petition to F1 (unmarried adult child of a citizen). The F1 line often runs longer than F2B, so the conversion can lengthen the wait. The law allows F2B beneficiaries to opt out of the automatic conversion and stay in F2B.² To do so, the beneficiary (not the parent) sends a signed letter to the USCIS office that approved the I-130, stating the wish to remain in F2B and including both parties’ names, dates of birth, and the I-130 receipt number. Compare current Visa Bulletin waits for both categories before deciding, because the choice sets the length of the remaining wait.
