Will My Child Age Out? The CSPA for Employment-Based Green Cards

The Problem CSPA Solves

When a parent receives an employment-based green card, their spouse and unmarried children under 21 can receive green cards too, as derivatives. But green card cases can take years, and a child who turns 21 along the way can "age out" and lose that eligibility.

The Child Status Protection Act (CSPA) reduces that risk. For derivative children in employment-based cases, it calculates a "CSPA age" that can be lower than the child's actual age (INA 203(h)). If the CSPA age is under 21, the child can still immigrate as a child.

The Formula

For employment-based derivative children, USCIS calculates CSPA age by taking the child's age on the date an immigrant visa becomes available, and subtracting the number of days the petition was pending (7 USCIS-PM A.7):

CSPA age = age when a visa becomes available − time the I-140 was pending

Pending time runs from the date the I-140 was filed to the date it was approved, and includes administrative review such as motions and appeals.
The child must remain unmarried. CSPA protects only unmarried children.

When a Visa "Becomes Available"

Two conditions must both be met: the petition must be approved, and the visa must be available for the parent's category, priority date, and country of chargeability. So the visa-availability date is the later of (7 USCIS-PM A.7(F)(4)):

The date the I-140 was approved; or
The first day of the month of the Visa Bulletin in which the Final Action Dates chart shows the priority date as current.

Dates for Filing does not lock the age

USCIS sometimes lets applicants file the green card application (Form I-485) using the earlier Dates for Filing chart. For example, USCIS designated the Dates for Filing chart for employment-based cases in October 2026. But for CSPA, USCIS uses the Final Action Dates chart. A child who files early under Dates for Filing has not yet locked in a CSPA age. The age is calculated, and locked in, when the Final Action Dates chart shows the priority date as current. A child who files early may turn out not to qualify if their CSPA age is 21 or older at that point.

For adjustment applications filed before August 15, 2025, USCIS used its earlier policy, based on when USCIS considered a visa available for filing. The Final Action Dates rule applies to applications filed on or after that date.

See our guide to the Visa Bulletin and priority dates.

Retrogression

The Visa Bulletin can move backward. CSPA treats that differently depending on timing (7 USCIS-PM A.7(F)(5)):

Filed while Final Action Dates was current, with a CSPA age under 21: the age is locked in through final decision. If the visa later becomes unavailable, USCIS holds the application until it is available again.
Filed under Dates for Filing: the age is locked in on the first day the Final Action Dates chart shows the date as current, even if it retrogresses later.
The visa became available, then retrogressed before anything was filed: the age is not locked in. It is recalculated when the visa next becomes available, and the child may have aged out by then.

The One-Year "Sought to Acquire" Deadline

To benefit from the CSPA calculation, the child must seek to acquire permanent residence within 1 year of the visa becoming available (INA 203(h)(1)(A); 7 USCIS-PM A.7(G)). Ways to meet this include:

Properly filing Form I-485, Application to Adjust Status
Submitting Part I of the immigrant visa application (Form DS-260) to the Department of State
Paying the immigrant visa fee to the Department of State
Paying the Affidavit of Support review fee, if the child is listed on it
Having a Form I-824 properly filed on the child's behalf

Preliminary steps, such as contacting an attorney, generally do not count. Missing the one-year window is excused only for extraordinary circumstances beyond the family's control. USCIS states that commonplace circumstances, such as financial difficulty, minor medical conditions, or decisions about when to seek counsel or prepare the application, are not extraordinary (7 USCIS-PM A.7(H)).

Birthday Deadlines and Weekends

USCIS has announced that, for paper filings received on or after October 23, 2026, it will not extend deadlines defined by a birthday, such as filing before a child turns 21, when the birthday falls on a weekend or federal holiday. Only deadlines expressed in a number of days roll over to the next business day (USCIS Policy Alert PA-2026-15). If any filing must be made before a 21st birthday, plan to file before the birthday itself.

An Example

A parent's I-140 was pending for 8 months before it was approved. Later, the parent's priority date becomes current on the Final Action Dates chart on March 1, when the child is 21 years and 5 months old. Because March 1 is later than the approval date, March 1 is the visa-availability date.

Age on the visa-availability date: 21 years, 5 months
Minus I-140 pending time: 8 months
CSPA age: 20 years, 9 months, so the child can still qualify, provided they remain unmarried and seek to acquire permanent residence within one year of March 1.

Note that because the formula subtracts the I-140 pending time, a petition approved faster leaves less time to subtract.

If a Child Will Age Out

If the CSPA age will be 21 or over, the child generally needs a separate path, such as their own student or work status, or their own immigrant petition. Planning that early, while the child is still a derivative, often gives the most options. For the parent's side, see our guides to EB-1A or NIW, adjustment of status vs. consular processing, and dependent work authorization.

Key Takeaways

CSPA age for an employment-based derivative child is the child's age when a visa becomes available, minus the time the I-140 was pending.
A visa becomes available on the later of I-140 approval or the first day of the month the Final Action Dates chart shows the priority date as current.
Filing early under the Dates for Filing chart does not lock in a CSPA age.
The child must remain unmarried and seek to acquire permanent residence within one year of visa availability.
From October 23, 2026, birthday-based deadlines do not roll over when the birthday falls on a weekend or holiday.
