What happens if your child turns 21 during immigration?

On Behalf of | Oct 15, 2026 | Family Immigration

Your child’s 21st birthday is approaching, but your family’s application for a green card is still pending. Could turning 21 affect your child’s chance to immigrate with you? The Child Status Protection Act (CSPA) may help prevent this, but eligibility depends on your immigration category and when you filed your petition.

How does the CSPA protect children turning 21?

Immigration law generally considers an unmarried person under 21 a child. However, the CSPA may allow some children to still qualify for a green card after reaching that age.

How the law applies depends on your circumstances:

  • Children of U.S. citizens: When you properly file Form I-130 for your unmarried child before they turn 21, their age generally becomes fixed on the filing date.
  • Children in other immigration cases: Some children may qualify through a parent’s family or work-based visa case. The government uses the age of the child when a visa becomes available or when USCIS approves the petition, whichever comes later. It then subtracts the number of days between filing and approval.

Your child must also stay unmarried until they receive a green card. In certain visa cases, they must seek a green card within a year after a visa becomes available. This may involve filing Form I-485, submitting Form DS-260 or paying the required immigrant visa fee. Missing the deadline can mean losing CSPA protection, although exceptions may apply.

What happens if your child no longer qualifies?

Without CSPA protection, your child may move to another visa category with longer waiting periods. In some cases, your child may lose eligibility under your application and need a separate petition.

The USCIS CSPA guidelines explain how filing dates, visa availability and other requirements affect eligibility.

Understanding your child’s immigration options

Your child’s eligibility depends on more than their 21st birthday. Filing dates, immigration categories and applicable deadlines can determine whether CSPA protection applies. An immigration attorney can review these details, assess whether your child qualifies and explain what options may remain if they no longer qualify under your petition.
