Aging Out: How the Child Status Protection Act Can Protect Your Child

Immigration » Immigration resources » Age-out and CSPA

A child must be under 21 to be treated as a child for most green card categories. Backlogs are long, and children sometimes turn 21 while a case is pending. The Child Status Protection Act, or CSPA, can protect some of them.

How the CSPA age is calculated

In general, CSPA lets the government subtract the time a petition was pending from the child’s age on the date a visa number became available. If the result is under 21, the child may still be treated as a child. The exact rule depends on the category.

• Immediate relatives: the child’s age is usually locked on the date the petition was filed.
• F2A (children of permanent residents): the age locked at the date a visa number became available, with extra rules that can help.
• Other family and employment derivatives: age at the time a visa became available, minus the time the petition was pending, but the child must act in time.

The one-year rule

A child who needs CSPA protection must generally apply for a green card within one year of a visa becoming available. Missing the window can lose the protection unless there are extraordinary circumstances, so track the monthly Visa Bulletin.

Other things that affect age

• Marriage ends child status in most categories.
• The category of the parent can change if the parent becomes a citizen. Our team reviews how a naturalization changes the child’s category.
• A person who turns 21 and cannot be protected may still have other options, such as a new petition, a different category, or a status such as student.

Dependents on work visas

Children on H-4 and similar dependent statuses age out of the status at 21 even if the green card case is still open. Plan the status change early. See H-4 extensions and age-out.

What to do now

• Calculate the child’s age on key dates: petition filing, approval and the date the category became current.
• Keep copies of all notices.
• Ask us before any change in marital status or in the parent’s status.
